• How Long Is a PhD Thesis?
• Doing a PhD

It’s no secret that one of the most challenging aspects of a PhD degree is the volume of work that goes into writing your thesis . So this raises the question, exactly how long is a thesis?

Unfortunately, there’s no one size fits all answer to this question. However, from the analysis of over 100 PhD theses, the average thesis length is between 80,000 and 100,000 words. A further analysis of 1000 PhD thesis shows the average number of pages to be 204 . In reality, the actual word count for each PhD thesis will depend on the specific subject and the university it is being hosted by. This is because universities set their own word length requirements, with most found to be opting for around 100,000.

To find out more about how these word limits differ between universities, how the average word count from STEM thesis differ from non-STEM thesis and a more detailed breakdown from the analysis of over 1000 PhDs, carry on reading the below.

Word Count Differences Between Universities

For any PhD student writing a thesis, they will find that their document will be subject to a word limit set by their university. In nearly all cases, the limit only concerns the maximum number of words and doesn’t place any restrictions on the minimum word limit. The reason for this is that the student will be expected to write their thesis with the aim of clearly explaining their research, and so it is up to the student to determine what he deems appropriate.

Saying this, it is well accepted amongst PhD students and supervisors that the absence of a lower limit doesn’t suggest that a thesis can be ‘light’. Your thesis will focus on several years worth of original research and explore new ideas, theories or concepts. Besides this, your thesis will need to cover a wide range of topics such as your literature review, research methodology, results and conclusion. Therefore, your examiners will expect the length of your thesis to be proportional to convey all this information to a sufficient level.

Selecting a handful of universities at random, they state the following thesis word limits on their website:

• University of Edinburgh: 100,000
• University of Exeter: 100,000
• University of Leister: 80,000
• University of Bath: 80,000
• University of Warwick: 70,000

The above universities set upper word limits that apply across the board, however, some universities, such as the University of Birmingham and the University of Sheffield, set different word limits for different departments. For example, the University of Sheffield adopts these limits:

• Arts & Humanities: 75,000
• Medicine, Dentistry & Health: 75,000
• Science: 80,000
• Social Sciences: 75,000-100,000

Although there’s a range of limit, it’s safe to say that the majority fall within the 80,000 to 100,000 bracket.

Word Count Based on Data from past Theses

A poll of 149 postdocs.

In mid-2019, Dr Eva Lantsoght, a published author, academic blogger and Structural Engineering Professor, conducted a poll which asked postgraduate doctoral students to share the length of their final thesis. 149 PostDoc students responded to the survey, with the majority reporting a length falling within the ‘80,000 – 120,000 words’ bracket as seen below.

Analysis of 1000 PhD Theses

Over a three-year time period, Dr Ian Brailsford, a then Postgraduate Learning Adviser at the University of Auckland, analysed 1000 doctoral thesis submitted to his university’s library. The PhD theses which formed the basis of his analysis were produced between 2008 to 2017 and showed:

• Average number of pages = 204
• Median number of pages = 198
• Average number of chapters = 7.6

We should note that the above metrics only cover the content falling within the main body of the thesis. This includes the introduction, literature review, methods section, results chapter, discussions and conclusions. All other sections, such as the title page, abstract, table of contents, acknowledgements, bibliography and appendices were omitted from the count.

Although it’s impossible to draw the exact word count from the number of pages alone, by using the universities recommended format of 12pt Times New Roman and 1.5 lines spacing, and assuming 10% of the main body are figures and footnotes, this equates to an average main body of 52,000 words.

STEM vs Non-STEM

As part of Dr Ian Brailsford’s analysis, he also compared the length of STEM doctorate theses to non-STEM theses. He found that STEM theses tended to be shorter. In fact, he found STEM theses to have a medium page length of 159 whilst non-STEM theses had a medium of around 223 pages. This is a 40% increase in average length!

Can You Exceed the Word Count?

Whilst most universities will allow you to go over the word count if you need to, it comes with the caveat that you must have a very strong reason for needing to do so. Besides this, your supervisor will also need to support your request. This is to acknowledge that they have reviewed your situation and agree that exceeding the word limit will be absolutely necessary to avoid detriment unnecessary detriment to your work.

This means that whilst it is possible to submit a thesis over 100,000 words or more, it’s unlikely that your research project will need to.

How Does This Compare to a Masters Dissertation?

The average Masters dissertation length is approximately 20,000 words whilst a thesis is 4 to 5 times this length at approximately 80,000 – 100,000.

The key reason for this difference is because of the level of knowledge they convey. A Master’s dissertation focuses on concluding from existing knowledge whilst a PhD thesis focuses on drawing a conclusion from new knowledge. As a result, the thesis is significantly longer as the new knowledge needs to be well documented so it can be verified, disseminated and used to shape future research.

Finding a PhD has never been this easy – search for a PhD by keyword, location or academic area of interest.

Embarking on a PhD is “probably the most challenging task that a young scholar attempts to do”, write Mark Stephan Felix and Ian Smith in their practical guide to dissertation and thesis writing. After years of reading and research to answer a specific question or proposition, the candidate will submit about 80,000 words that explain their methods and results and demonstrate their unique contribution to knowledge. Here are the answers to frequently asked questions about writing a doctoral thesis or dissertation.

What’s the difference between a dissertation and a thesis?

Whatever the genre of the doctorate, a PhD must offer an original contribution to knowledge. The terms “dissertation” and “thesis” both refer to the long-form piece of work produced at the end of a research project and are often used interchangeably. Which one is used might depend on the country, discipline or university. In the UK, “thesis” is generally used for the work done for a PhD, while a “dissertation” is written for a master’s degree. The US did the same until the 1960s, says Oxbridge Essays, when the convention switched, and references appeared to a “master’s thesis” and “doctoral dissertation”. To complicate matters further, undergraduate long essays are also sometimes referred to as a thesis or dissertation.

The Oxford English Dictionary defines “thesis” as “a dissertation, especially by a candidate for a degree” and “dissertation” as “a detailed discourse on a subject, especially one submitted in partial fulfilment of the requirements of a degree or diploma”.

The title “doctor of philosophy”, incidentally, comes from the degree’s origins, write Dr Felix, an associate professor at Mahidol University in Thailand, and Dr Smith, retired associate professor of education at the University of Sydney , whose co-authored guide focuses on the social sciences. The PhD was first awarded in the 19th century by the philosophy departments of German universities, which at that time taught science, social science and liberal arts.

How long should a PhD thesis be?

A PhD thesis (or dissertation) is typically 60,000 to 120,000 words ( 100 to 300 pages in length ) organised into chapters, divisions and subdivisions (with roughly 10,000 words per chapter) – from introduction (with clear aims and objectives) to conclusion.

The structure of a dissertation will vary depending on discipline (humanities, social sciences and STEM all have their own conventions), location and institution. Examples and guides to structure proliferate online. The University of Salford , for example, lists: title page, declaration, acknowledgements, abstract, table of contents, lists of figures, tables and abbreviations (where needed), chapters, appendices and references.

A scientific-style thesis will likely need: introduction, literature review, materials and methods, results, discussion, bibliography and references.

As well as checking the overall criteria and expectations of your institution for your research, consult your school handbook for the required length and format (font, layout conventions and so on) for your dissertation.

A PhD takes three to four years to complete; this might extend to six to eight years for a part-time doctorate.

What are the steps for completing a PhD?

Before you get started in earnest , you’ll likely have found a potential supervisor, who will guide your PhD journey, and done a research proposal (which outlines what you plan to research and how) as part of your application, as well as a literature review of existing scholarship in the field, which may form part of your final submission.

In the UK, PhD candidates undertake original research and write the results in a thesis or dissertation, says author and vlogger Simon Clark , who posted videos to YouTube throughout his own PhD journey . Then they submit the thesis in hard copy and attend the viva voce (which is Latin for “living voice” and is also called an oral defence or doctoral defence) to convince the examiners that their work is original, understood and all their own. Afterwards, if necessary, they make changes and resubmit. If the changes are approved, the degree is awarded.

The steps are similar in Australia , although candidates are mostly assessed on their thesis only; some universities may include taught courses, and some use a viva voce. A PhD in Australia usually takes three years full time.

In the US, the PhD process begins with taught classes (similar to a taught master’s) and a comprehensive exam (called a “field exam” or “dissertation qualifying exam”) before the candidate embarks on their original research. The whole journey takes four to six years.

A PhD candidate will need three skills and attitudes to get through their doctoral studies, says Tara Brabazon , professor of cultural studies at Flinders University in Australia who has written extensively about the PhD journey :

• master the academic foundational skills (research, writing, ability to navigate different modalities)
• time-management skills and the ability to focus on reading and writing
• determined motivation to do a PhD.

How do I choose the topic for my PhD dissertation or thesis?

It’s important to find a topic that will sustain your interest for the years it will take to complete a PhD. “Finding a sustainable topic is the most important thing you [as a PhD student] would do,” says Dr Brabazon in a video for Times Higher Education . “Write down on a big piece of paper all the topics, all the ideas, all the questions that really interest you, and start to cross out all the ones that might just be a passing interest.” Also, she says, impose the “Who cares? Who gives a damn?” question to decide if the topic will be useful in a future academic career.

The availability of funding and scholarships is also often an important factor in this decision, says veteran PhD supervisor Richard Godwin, from Harper Adams University .

Define a gap in knowledge – and one that can be questioned, explored, researched and written about in the time available to you, says Gina Wisker, head of the Centre for Learning and Teaching at the University of Brighton. “Set some boundaries,” she advises. “Don’t try to ask everything related to your topic in every way.”

James Hartley, research professor in psychology at Keele University, says it can also be useful to think about topics that spark general interest. If you do pick something that taps into the zeitgeist, your findings are more likely to be noticed.

You also need to find someone else who is interested in it, too. For STEM candidates , this will probably be a case of joining a team of people working in a similar area where, ideally, scholarship funding is available. A centre for doctoral training (CDT) or doctoral training partnership (DTP) will advertise research projects. For those in the liberal arts and social sciences, it will be a matter of identifying a suitable supervisor .

Avoid topics that are too broad (hunger across a whole country, for example) or too narrow (hunger in a single street) to yield useful solutions of academic significance, write Mark Stephan Felix and Ian Smith. And ensure that you’re not repeating previous research or trying to solve a problem that has already been answered. A PhD thesis must be original.

What is a thesis proposal?

After you have read widely to refine your topic and ensure that it and your research methods are original, and discussed your project with a (potential) supervisor, you’re ready to write a thesis proposal , a document of 1,500 to 3,000 words that sets out the proposed direction of your research. In the UK, a research proposal is usually part of the application process for admission to a research degree. As with the final dissertation itself, format varies among disciplines, institutions and countries but will usually contain title page, aims, literature review, methodology, timetable and bibliography. Examples of research proposals are available online.

How to write an abstract for a dissertation or thesis

The abstract presents your thesis to the wider world – and as such may be its most important element , says the NUI Galway writing guide. It outlines the why, how, what and so what of the thesis . Unlike the introduction, which provides background but not research findings, the abstract summarises all sections of the dissertation in a concise, thorough, focused way and demonstrates how well the writer understands their material. Check word-length limits with your university – and stick to them. About 300 to 500 words is a rough guide ­– but it can be up to 1,000 words.

The abstract is also important for selection and indexing of your thesis, according to the University of Melbourne guide , so be sure to include searchable keywords.

It is the first thing to be read but the last element you should write. However, Pat Thomson , professor of education at the University of Nottingham , advises that it is not something to be tackled at the last minute.

How to write a stellar conclusion

As well as chapter conclusions, a thesis often has an overall conclusion to draw together the key points covered and to reflect on the unique contribution to knowledge. It can comment on future implications of the research and open up new ideas emanating from the work. It is shorter and more general than the discussion chapter , says online editing site Scribbr, and reiterates how the work answers the main question posed at the beginning of the thesis. The conclusion chapter also often discusses the limitations of the research (time, scope, word limit, access) in a constructive manner.

It can be useful to keep a collection of ideas as you go – in the online forum DoctoralWriting SIG , academic developer Claire Aitchison, of the University of South Australia , suggests using a “conclusions bank” for themes and inspirations, and using free-writing to keep this final section fresh. (Just when you feel you’ve run out of steam.) Avoid aggrandising or exaggerating the impact of your work. It should remind the reader what has been done, and why it matters.

How to format a bibliography (or where to find a reliable model)

Most universities use a preferred style of references , writes THE associate editor Ingrid Curl. Make sure you know what this is and follow it. “One of the most common errors in academic writing is to cite papers in the text that do not then appear in the bibliography. All references in your thesis need to be cross-checked with the bibliography before submission. Using a database during your research can save a great deal of time in the writing-up process.”

A bibliography contains not only works cited explicitly but also those that have informed or contributed to the research – and as such illustrates its scope; works are not limited to written publications but include sources such as film or visual art.

Examiners can start marking from the back of the script, writes Dr Brabazon. “Just as cooks are judged by their ingredients and implements, we judge doctoral students by the calibre of their sources,” she advises. She also says that candidates should be prepared to speak in an oral examination of the PhD about any texts included in their bibliography, especially if there is a disconnect between the thesis and the texts listed.

Can I use informal language in my PhD?

Don’t write like a stereotypical academic , say Kevin Haggerty, professor of sociology at the University of Alberta , and Aaron Doyle, associate professor in sociology at Carleton University , in their tongue-in-cheek guide to the PhD journey. “If you cannot write clearly and persuasively, everything about PhD study becomes harder.” Avoid jargon, exotic words, passive voice and long, convoluted sentences – and work on it consistently. “Writing is like playing guitar; it can improve only through consistent, concerted effort.”

Be deliberate and take care with your writing . “Write your first draft, leave it and then come back to it with a critical eye. Look objectively at the writing and read it closely for style and sense,” advises THE ’s Ms Curl. “Look out for common errors such as dangling modifiers, subject-verb disagreement and inconsistency. If you are too involved with the text to be able to take a step back and do this, then ask a friend or colleague to read it with a critical eye. Remember Hemingway’s advice: ‘Prose is architecture, not interior decoration.’ Clarity is key.”

How often should a PhD candidate meet with their supervisor?

Since the PhD supervisor provides a range of support and advice – including on research techniques, planning and submission – regular formal supervisions are essential, as is establishing a line of contact such as email if the candidate needs help or advice outside arranged times. The frequency varies according to university, discipline and individual scholars.

Once a week is ideal, says Dr Brabazon. She also advocates a two-hour initial meeting to establish the foundations of the candidate-supervisor relationship .

The University of Edinburgh guide to writing a thesis suggests that creating a timetable of supervisor meetings right at the beginning of the research process will allow candidates to ensure that their work stays on track throughout. The meetings are also the place to get regular feedback on draft chapters.

“A clear structure and a solid framework are vital for research,” writes Dr Godwin on THE Campus . Use your supervisor to establish this and provide a realistic view of what can be achieved. “It is vital to help students identify the true scientific merit, the practical significance of their work and its value to society.”

How to proofread your dissertation (what to look for)

Proofreading is the final step before printing and submission. Give yourself time to ensure that your work is the best it can be . Don’t leave proofreading to the last minute; ideally, break it up into a few close-reading sessions. Find a quiet place without distractions. A checklist can help ensure that all aspects are covered.

Proofing is often helped by a change of format – so it can be easier to read a printout rather than working off the screen – or by reading sections out of order. Fresh eyes are better at spotting typographical errors and inconsistencies, so leave time between writing and proofreading. Check with your university’s policies before asking another person to proofread your thesis for you.

As well as close details such as spelling and grammar, check that all sections are complete, all required elements are included , and nothing is repeated or redundant. Don’t forget to check headings and subheadings. Does the text flow from one section to another? Is the structure clear? Is the work a coherent whole with a clear line throughout?

Ensure consistency in, for example, UK v US spellings, capitalisation, format, numbers (digits or words, commas, units of measurement), contractions, italics and hyphenation. Spellchecks and online plagiarism checkers are also your friend.

How do you manage your time to complete a PhD dissertation?

Treat your PhD like a full-time job, that is, with an eight-hour working day. Within that, you’ll need to plan your time in a way that gives a sense of progress . Setbacks and periods where it feels as if you are treading water are all but inevitable, so keeping track of small wins is important, writes A Happy PhD blogger Luis P. Prieto.

Be specific with your goals – use the SMART acronym (specific, measurable, attainable, relevant and timely).

And it’s never too soon to start writing – even if early drafts are overwritten and discarded.

“ Write little and write often . Many of us make the mistake of taking to writing as one would take to a sprint, in other words, with relatively short bursts of intense activity. Whilst this can prove productive, generally speaking it is not sustainable…In addition to sustaining your activity, writing little bits on a frequent basis ensures that you progress with your thinking. The comfort of remaining in abstract thought is common; writing forces us to concretise our thinking,” says Christian Gilliam, AHSS researcher developer at the University of Cambridge ’s Centre for Teaching and Learning.

Make time to write. “If you are more alert early in the day, find times that suit you in the morning; if you are a ‘night person’, block out some writing sessions in the evenings,” advises NUI Galway’s Dermot Burns, a lecturer in English and creative arts. Set targets, keep daily notes of experiment details that you will need in your thesis, don’t confuse writing with editing or revising – and always back up your work.

What work-life balance tips should I follow to complete my dissertation?

During your PhD programme, you may have opportunities to take part in professional development activities, such as teaching, attending academic conferences and publishing your work. Your research may include residencies, field trips or archive visits. This will require time-management skills as well as prioritising where you devote your energy and factoring in rest and relaxation. Organise your routine to suit your needs , and plan for steady and regular progress.

How to deal with setbacks while writing a thesis or dissertation

Have a contingency plan for delays or roadblocks such as unexpected results.

Accept that writing is messy, first drafts are imperfect, and writer’s block is inevitable, says Dr Burns. His tips for breaking it include relaxation to free your mind from clutter, writing a plan and drawing a mind map of key points for clarity. He also advises feedback, reflection and revision: “Progressing from a rough version of your thoughts to a superior and workable text takes time, effort, different perspectives and some expertise.”

“Academia can be a relentlessly brutal merry-go-round of rejection, rebuttal and failure,” writes Lorraine Hope , professor of applied cognitive psychology at the University of Portsmouth, on THE Campus. Resilience is important. Ensure that you and your supervisor have a relationship that supports open, frank, judgement-free communication.

How long is a dissertation, published by steve tippins on april 9, 2019 april 9, 2019.

Last Updated on: 2nd February 2024, 05:03 am

How long is a dissertation? This is a question that almost every doctoral student asks at some point. It is not a new question–in fact, it’s been asked every time a paper of some sort is assigned in any class.

The simple answer (for any paper) is, “long enough to answer the question.” Not a really helpful answer, but satisfying from a professor’s perspective.

The truth is, there is no one answer to how long a dissertation is. I can’t say 146 pages is what’s needed, as you may write to page 146 and stop without fully exploring your topic. 90 pages could adequately address your research question, or you could write 200 pages and still not fully answer what you set out to. Every topic is unique, as is each person’s writing style.

Some websites even give specific answers that are simply inaccurate. In my experience, dissertations vary too much to be pinned down like that.

However, there are some practical suggestions I can make about how long your dissertation should be, how to adequately address the requirements of each section, as well as how to expand or reduce the length of specific chapters according to your needs. I’ll explore these below.

But first, let’s try and at least give the beginning of an answer to the question “how long is a dissertation?”

Marcus Beck Sets Out to Answer “How Long Is A Dissertation?”

Any discussion of dissertation length must include the work done by Marcus Beck . As a way to distract himself from his own dissertation writing, Beck calculated the average length of dissertations in the University of Minnesota database.

You can see from looking at his data that average length varies by discipline. So the first answer to how long a dissertation is, is that it depends upon what area you are writing your dissertation. It appears that a dissertation in History will be much longer, on average, than one in Chemistry. He also calculated the average across all disciplines.

Don’t be intimidated by how long the average dissertation is.

Many people look at the average length of a dissertation and get intimidated by the high page count. But, as Marcus Beck says in his blog post, “The actual written portion may only account for less than 50% of the page length.”

I’ve found this to be true. References, appendixes, tables and figures, page breaks, and white space all contribute to the high page count. The actual number of words you need to write is likely considerably less than the page count initially implies.

How Long Should My Dissertation Be?

Even though there’s no single answer about how long a dissertation should be, there probably is an ideal range which your dissertation falls into. This depends on your topic of research, but also on other factors. I’ll discuss some of these below.

Institutional Guidelines

I know of schools that have policies such as “Chapter 2 must be at least 40 pages long and no more than 60 pages.” Why this type of requirement? In my mind, there are two reasons.

First, they want to give some sort of guideline for students that is helpful but does not overburden faculty (a 230-page lit review is daunting to read).

Second, credibility is important. An 8-page lit review does not reflect well upon the student or the institution.

Most schools now have a dissertation template with the headings that are needed for most sections. If you take the time to completely fill in the headings with all of the relevant information, you should come up with an adequate number of pages. Remember, in academic writing, we don’t leave much to chance, we tell the reader everything.

Committee Preferences

It is likely that you will get a committee member who will give you priceless advice such as, “more is needed here.” When you get this type of comment it can be frustrating as specific feedback can be much more helpful.

Usually, what a committee member means by comments like this is that you haven’t really convinced the reader that you have fully explored the area or demonstrated a strong understanding of the material. So, expand what you are saying. Don’t imply anything, state it directly. This lets your committee know that you really do get it.

Sometimes you will get committee members giving contradictory advice. One member may want more information and another may want less. My first piece of advice is to negotiate these types of requests through your Chairperson.

This is where your Chair’s experience and guidance can be very helpful. Second, if a member really wants material included but others do not think it is very helpful, then adding the material in an appendix may make everyone happy.

Practical Suggestions For Dissertation Length, Chapter-By-Chapter

If you adequately and succinctly address each required section, you should end up with the right length for each chapter (and therefore, a dissertation of the right length). I’ll also give some rough guidelines on average page length where appropriate.

This is the introduction to your study. It is important to lay out the agenda for your research. Be sure that your problem statement, title, and research questions are in alignment (all referring to the same idea).

Chapter 1 tends to average in the 15-25 page range. If you get beyond 25 pages, you are usually including material that is better presented elsewhere in the dissertation.

Chapter 2 should thoroughly explore the existing research on your topic. However, it shouldn’t go on and on.

• If you are looking to beef up Chapter 2, it is always helpful to add research that supports the methodology that you are planning to use.
• If the chapter is too long, try to reduce the references you cite to those that are the most relevant and recent.

Make sure that you tell the reader what you did and how you did it. What type of analysis did you use and why? How many respondents were involved and how did you find them? The idea is to make sure that readers understand what you did and could replicate it if they want to.

As this is a plan for your research, it seems to naturally fall in the 15 to 20 page range.

The results of your study are presented here. Include all material that will help the reader understand what you found. There is a tendency to inundate the reader with tables, charts, and graphs. If they don’t directly relate to what you found or are redundant they can be included in an appendix. You don’t want to lose your reader in an avalanche of tables and numbers.

In most dissertations, it is Chapter 5 where you get to explain what the results of your research mean and the implications. This is the only chapter where you have some freedom to really express your opinions. Go ahead and do so.

I am always surprised when someone has spent 15 months of their life working on a research topic and they submit a Chapter 5 that is 8 pages long. Spread your wings and really explore what your results mean.

How Long is a Dissertation? Summary

The is no doubt about it, a dissertation is a long document. It is, however, not written in one sitting. You work on it for many months, crafting paragraphs and coming to conclusions. Many people find that because the document can be written in pieces that when it’s all put together, it is longer than expected. Keep writing and adding your thoughts and you will make it.

Many students find it helps to have a supportive guide who’s both been through the dissertation writing process before and is experienced in helping students. If that would be useful to you, feel free to reach out to me about my dissertation coaching or dissertation editing services.

Front and Back Matter

Supplemental material, dissertations comprising previously published works, top ten formatting errors, further questions.

• Related Contacts and Forms

When preparing the dissertation for submission, students must follow strict formatting requirements. Any deviation from these requirements may lead to rejection of the dissertation and delay in the conferral of the degree.

The language of the dissertation is ordinarily English, although some departments whose subject matter involves foreign languages may accept a dissertation written in a language other than English.

Most dissertations are 100 to 300 pages in length. All dissertations should be divided into appropriate sections, and long dissertations may need chapters, main divisions, and subdivisions.

• 8½ x 11 inches, unless a musical score is included
• At least 1 inch for all margins
• Body of text: double spacing
• Block quotations, footnotes, and bibliographies: single spacing within each entry but double spacing between each entry
• Table of contents, list of tables, list of figures or illustrations, and lengthy tables: single spacing may be used

Fonts and Point Size

Use 10-12 point size. Fonts must be embedded in the PDF file to ensure all characters display correctly. 

Recommended Fonts

If you are unsure whether your chosen font will display correctly, use one of the following fonts: 

If fonts are not embedded, non-English characters may not appear as intended. Fonts embedded improperly will be published to DASH as-is. It is the student’s responsibility to make sure that fonts are embedded properly prior to submission. 

Instructions for Embedding Fonts

To embed your fonts in recent versions of Word, follow these instructions from Microsoft:

• Click the File tab and then click Options .
• In the left column, select the Save tab.
• Clear the Do not embed common system fonts check box.

For reference, below are some instructions from ProQuest UMI for embedding fonts in older file formats:

To embed your fonts in Microsoft Word 2010:

• In the File pull-down menu click on Options .
• Choose Save on the left sidebar.
• Check the box next to Embed fonts in the file.
• Click the OK button.
• Save the document.

Note that when saving as a PDF, make sure to go to “more options” and save as “PDF/A compliant”

To embed your fonts in Microsoft Word 2007:

• Click the circular Office button in the upper left corner of Microsoft Word.
• A new window will display. In the bottom right corner select Word Options . 
• Choose Save from the left sidebar.

Using Microsoft Word on a Mac:

Microsoft Word 2008 on a Mac OS X computer will automatically embed your fonts while converting your document to a PDF file.

If you are converting to PDF using Acrobat Professional (instructions courtesy of the Graduate Thesis Office at Iowa State University):  

• Open your document in Microsoft Word. 
• Click on the Adobe PDF tab at the top. Select "Change Conversion Settings." 
• Click on Advanced Settings. 
• Click on the Fonts folder on the left side of the new window. In the lower box on the right, delete any fonts that appear in the "Never Embed" box. Then click "OK." 
• If prompted to save these new settings, save them as "Embed all fonts." 
• Now the Change Conversion Settings window should show "embed all fonts" in the Conversion Settings drop-down list and it should be selected. Click "OK" again. 
• Click on the Adobe PDF link at the top again. This time select Convert to Adobe PDF. Depending on the size of your document and the speed of your computer, this process can take 1-15 minutes. 
• After your document is converted, select the "File" tab at the top of the page. Then select "Document Properties." 
• Click on the "Fonts" tab. Carefully check all of your fonts. They should all show "(Embedded Subset)" after the font name. 
•  If you see "(Embedded Subset)" after all fonts, you have succeeded.

The font used in the body of the text must also be used in headers, page numbers, and footnotes. Exceptions are made only for tables and figures created with different software and inserted into the document.

Tables and figures must be placed as close as possible to their first mention in the text. They may be placed on a page with no text above or below, or they may be placed directly into the text. If a table or a figure is alone on a page (with no narrative), it should be centered within the margins on the page. Tables may take up more than one page as long as they obey all rules about margins. Tables and figures referred to in the text may not be placed at the end of the chapter or at the end of the dissertation.

• Given the standards of the discipline, dissertations in the Department of History of Art and Architecture and the Department of Architecture, Landscape Architecture, and Urban Planning often place illustrations at the end of the dissertation.

Figure and table numbering must be continuous throughout the dissertation or by chapter (e.g., 1.1, 1.2, 2.1, 2.2, etc.). Two figures or tables cannot be designated with the same number. If you have repeating images that you need to cite more than once, label them with their number and A, B, etc. 

Headings should be placed at the top of tables. While no specific rules for the format of table headings and figure captions are required, a consistent format must be used throughout the dissertation (contact your department for style manuals appropriate to the field).

Captions should appear at the bottom of any figures. If the figure takes up the entire page, the caption should be placed alone on the preceding page, centered vertically and horizontally within the margins.

Each page receives a separate page number. When a figure or table title is on a preceding page, the second and subsequent pages of the figure or table should say, for example, “Figure 5 (Continued).” In such an instance, the list of figures or tables will list the page number containing the title. The word “figure” should be written in full (not abbreviated), and the “F” should be capitalized (e.g., Figure 5). In instances where the caption continues on a second page, the “(Continued)” notation should appear on the second and any subsequent page. The figure/table and the caption are viewed as one entity and the numbering should show correlation between all pages. Each page must include a header.

Landscape orientation figures and tables must be positioned correctly and bound at the top so that the top of the figure or table will be at the left margin. Figure and table headings/captions are placed with the same orientation as the figure or table when on the same page. When on a separate page, headings/captions are always placed in portrait orientation, regardless of the orientation of the figure or table. Page numbers are always placed as if the figure were vertical on the page.

If a graphic artist does the figures, Harvard Griffin GSAS will accept lettering done by the artist only within the figure. Figures done with software are acceptable if the figures are clear and legible. Legends and titles done by the same process as the figures will be accepted if they too are clear, legible, and run at least 10 or 12 characters per inch. Otherwise, legends and captions should be printed with the same font used in the text.

Original illustrations, photographs, and fine arts prints may be scanned and included, centered between the margins on a page with no text above or below.

Use of Third-Party Content

In addition to the student's own writing, dissertations often contain third-party content or in-copyright content owned by parties other than you, the student who authored the dissertation. The Office for Scholarly Communication recommends consulting the information below about fair use, which allows individuals to use in-copyright content, on a limited basis and for specific purposes, without seeking permission from copyright holders.

Because your dissertation will be made available for online distribution through DASH , Harvard's open-access repository, it is important that any third-party content in it may be made available in this way.

Fair Use and Copyright 

What is fair use?

Fair use is a provision in copyright law that allows the use of a certain amount of copyrighted material without seeking permission. Fair use is format- and media-agnostic. This means fair use may apply to images (including photographs, illustrations, and paintings), quoting at length from literature, videos, and music regardless of the format. 

How do I determine whether my use of an image or other third-party content in my dissertation is fair use?  

There are four factors you will need to consider when making a fair use claim.

1) For what purpose is your work going to be used?

• Nonprofit, educational, scholarly, or research use favors fair use. Commercial, non-educational uses, often do not favor fair use.
• A transformative use (repurposing or recontextualizing the in-copyright material) favors fair use. Examining, analyzing, and explicating the material in a meaningful way, so as to enhance a reader's understanding, strengthens your fair use argument. In other words, can you make the point in the thesis without using, for instance, an in-copyright image? Is that image necessary to your dissertation? If not, perhaps, for copyright reasons, you should not include the image.  

2) What is the nature of the work to be used?

• Published, fact-based content favors fair use and includes scholarly analysis in published academic venues. 
• Creative works, including artistic images, are afforded more protection under copyright, and depending on your use in light of the other factors, may be less likely to favor fair use; however, this does not preclude considerations of fair use for creative content altogether.

3) How much of the work is going to be used?  

• Small, or less significant, amounts favor fair use. A good rule of thumb is to use only as much of the in-copyright content as necessary to serve your purpose. Can you use a thumbnail rather than a full-resolution image? Can you use a black-and-white photo instead of color? Can you quote select passages instead of including several pages of the content? These simple changes bolster your fair use of the material.

4) What potential effect on the market for that work may your use have?

• If there is a market for licensing this exact use or type of educational material, then this weighs against fair use. If however, there would likely be no effect on the potential commercial market, or if it is not possible to obtain permission to use the work, then this favors fair use. 

For further assistance with fair use, consult the Office for Scholarly Communication's guide, Fair Use: Made for the Harvard Community and the Office of the General Counsel's Copyright and Fair Use: A Guide for the Harvard Community .

What are my options if I don’t have a strong fair use claim? 

Consider the following options if you find you cannot reasonably make a fair use claim for the content you wish to incorporate:

• Seek permission from the copyright holder. 
• Use openly licensed content as an alternative to the original third-party content you intended to use. Openly-licensed content grants permission up-front for reuse of in-copyright content, provided your use meets the terms of the open license.
• Use content in the public domain, as this content is not in-copyright and is therefore free of all copyright restrictions. Whereas third-party content is owned by parties other than you, no one owns content in the public domain; everyone, therefore, has the right to use it.

For use of images in your dissertation, please consult this guide to Finding Public Domain & Creative Commons Media , which is a great resource for finding images without copyright restrictions. 

Who can help me with questions about copyright and fair use?

Contact your Copyright First Responder . Please note, Copyright First Responders assist with questions concerning copyright and fair use, but do not assist with the process of obtaining permission from copyright holders.

Pages should be assigned a number except for the Dissertation Acceptance Certificate . Preliminary pages (abstract, table of contents, list of tables, graphs, illustrations, and preface) should use small Roman numerals (i, ii, iii, iv, v, etc.). All pages must contain text or images.  

Count the title page as page i and the copyright page as page ii, but do not print page numbers on either page .

For the body of text, use Arabic numbers (1, 2, 3, 4, 5, etc.) starting with page 1 on the first page of text. Page numbers must be centered throughout the manuscript at the top or bottom. Every numbered page must be consecutively ordered, including tables, graphs, illustrations, and bibliography/index (if included); letter suffixes (such as 10a, 10b, etc.) are not allowed. It is customary not to have a page number on the page containing a chapter heading.

• Check pagination carefully. Account for all pages.

A copy of the Dissertation Acceptance Certificate (DAC) should appear as the first page. This page should not be counted or numbered. The DAC will appear in the online version of the published dissertation. The author name and date on the DAC and title page should be the same. 

The dissertation begins with the title page; the title should be as concise as possible and should provide an accurate description of the dissertation. The author name and date on the DAC and title page should be the same. 

• Do not print a page number on the title page. It is understood to be page  i  for counting purposes only.

A copyright notice should appear on a separate page immediately following the title page and include the copyright symbol ©, the year of first publication of the work, and the name of the author:

© [ year ] [ Author’s Name ] All rights reserved.

Alternatively, students may choose to license their work openly under a  Creative Commons  license. The author remains the copyright holder while at the same time granting up-front permission to others to read, share, and (depending on the license) adapt the work, so long as proper attribution is given. (By default, under copyright law, the author reserves all rights; under a Creative Commons license, the author reserves some rights.)

• Do  not  print a page number on the copyright page. It is understood to be page  ii  for counting purposes only.

An abstract, numbered as page  iii , should immediately follow the copyright page and should state the problem, describe the methods and procedures used, and give the main results or conclusions of the research. The abstract will appear in the online and bound versions of the dissertation and will be published by ProQuest. There is no maximum word count for the abstract. 

• double-spaced
• left-justified
• indented on the first line of each paragraph
• The author’s name, right justified
• The words “Dissertation Advisor:” followed by the advisor’s name, left-justified (a maximum of two advisors is allowed)
• Title of the dissertation, centered, several lines below author and advisor

Dissertations divided into sections must contain a table of contents that lists, at minimum, the major headings in the following order:

• Front Matter
• Body of Text
• Back Matter

Front matter includes (if applicable):

• acknowledgements of help or encouragement from individuals or institutions
• a dedication
• a list of illustrations or tables
• a glossary of terms
• one or more epigraphs.

Back matter includes (if applicable):

• bibliography
• supplemental materials, including figures and tables
• an index (in rare instances).

Supplemental figures and tables must be placed at the end of the dissertation in an appendix, not within or at the end of a chapter. If additional digital information (including audio, video, image, or datasets) will accompany the main body of the dissertation, it should be uploaded as a supplemental file through ProQuest ETD . Supplemental material will be available in DASH and ProQuest and preserved digitally in the Harvard University Archives.

As a matter of copyright, dissertations comprising the student's previously published works must be authorized for distribution from DASH. The guidelines in this section pertain to any previously published material that requires permission from publishers or other rightsholders before it may be distributed from DASH. Please note:

• Authors whose publishing agreements grant the publisher exclusive rights to display, distribute, and create derivative works will need to seek the publisher's permission for nonexclusive use of the underlying works before the dissertation may be distributed from DASH.
• Authors whose publishing agreements indicate the authors have retained the relevant nonexclusive rights to the original materials for display, distribution, and the creation of derivative works may distribute the dissertation as a whole from DASH without need for further permissions.

It is recommended that authors consult their publishing agreements directly to determine whether and to what extent they may have transferred exclusive rights under copyright. The Office for Scholarly Communication (OSC) is available to help the author determine whether she has retained the necessary rights or requires permission. Please note, however, the Office of Scholarly Communication is not able to assist with the permissions process itself.

• Missing Dissertation Acceptance Certificate.  The first page of the PDF dissertation file should be a scanned copy of the Dissertation Acceptance Certificate (DAC). This page should not be counted or numbered as a part of the dissertation pagination.
• Conflicts Between the DAC and the Title Page.  The DAC and the dissertation title page must match exactly, meaning that the author name and the title on the title page must match that on the DAC. If you use your full middle name or just an initial on one document, it must be the same on the other document.  
• Abstract Formatting Errors. The advisor name should be left-justified, and the author's name should be right-justified. Up to two advisor names are allowed. The Abstract should be double spaced and include the page title “Abstract,” as well as the page number “iii.” There is no maximum word count for the abstract. 
•  The front matter should be numbered using Roman numerals (iii, iv, v, …). The title page and the copyright page should be counted but not numbered. The first printed page number should appear on the Abstract page (iii). 
• The body of the dissertation should be numbered using Arabic numbers (1, 2, 3, …). The first page of the body of the text should begin with page 1. Pagination may not continue from the front matter. 
• All page numbers should be centered either at the top or the bottom of the page.
• Figures and tables Figures and tables must be placed within the text, as close to their first mention as possible. Figures and tables that span more than one page must be labeled on each page. Any second and subsequent page of the figure/table must include the “(Continued)” notation. This applies to figure captions as well as images. Each page of a figure/table must be accounted for and appropriately labeled. All figures/tables must have a unique number. They may not repeat within the dissertation.
• Any figures/tables placed in a horizontal orientation must be placed with the top of the figure/ table on the left-hand side. The top of the figure/table should be aligned with the spine of the dissertation when it is bound. 
• Page numbers must be placed in the same location on all pages of the dissertation, centered, at the bottom or top of the page. Page numbers may not appear under the table/ figure.
• Supplemental Figures and Tables. Supplemental figures and tables must be placed at the back of the dissertation in an appendix. They should not be placed at the back of the chapter. 
• Permission Letters Copyright. permission letters must be uploaded as a supplemental file, titled ‘do_not_publish_permission_letters,” within the dissertation submission tool.
•  DAC Attachment. The signed Dissertation Acceptance Certificate must additionally be uploaded as a document in the "Administrative Documents" section when submitting in Proquest ETD . Dissertation submission is not complete until all documents have been received and accepted.
• Overall Formatting. The entire document should be checked after all revisions, and before submitting online, to spot any inconsistencies or PDF conversion glitches.
• You can view dissertations successfully published from your department in DASH . This is a great place to check for specific formatting and area-specific conventions.
• Contact the  Office of Student Affairs  with further questions.

Know How to Structure Your PhD Thesis

• 4 minute read
• 33.7K views

Table of Contents

In your academic career, few projects are more important than your PhD thesis. Unfortunately, many university professors and advisors assume that their students know how to structure a PhD. Books have literally been written on the subject, but there’s no need to read a book in order to know about PhD thesis paper format and structure. With that said, however, it’s important to understand that your PhD thesis format requirement may not be the same as another student’s. The bottom line is that how to structure a PhD thesis often depends on your university and department guidelines.

But, let’s take a look at a general PhD thesis format. We’ll look at the main sections, and how to connect them to each other. We’ll also examine different hints and tips for each of the sections. As you read through this toolkit, compare it to published PhD theses in your area of study to see how a real-life example looks.

Main Sections of a PhD Thesis

In almost every PhD thesis or dissertation, there are standard sections. Of course, some of these may differ, depending on your university or department requirements, as well as your topic of study, but this will give you a good idea of the basic components of a PhD thesis format.

• Abstract : The abstract is a brief summary that quickly outlines your research, touches on each of the main sections of your thesis, and clearly outlines your contribution to the field by way of your PhD thesis. Even though the abstract is very short, similar to what you’ve seen in published research articles, its impact shouldn’t be underestimated. The abstract is there to answer the most important question to the reviewer. “Why is this important?”
• Introduction : In this section, you help the reviewer understand your entire dissertation, including what your paper is about, why it’s important to the field, a brief description of your methodology, and how your research and the thesis are laid out. Think of your introduction as an expansion of your abstract.
• Literature Review : Within the literature review, you are making a case for your new research by telling the story of the work that’s already been done. You’ll cover a bit about the history of the topic at hand, and how your study fits into the present and future.
• Theory Framework : Here, you explain assumptions related to your study. Here you’re explaining to the review what theoretical concepts you might have used in your research, how it relates to existing knowledge and ideas.
• Methods : This section of a PhD thesis is typically the most detailed and descriptive, depending of course on your research design. Here you’ll discuss the specific techniques you used to get the information you were looking for, in addition to how those methods are relevant and appropriate, as well as how you specifically used each method described.
• Results : Here you present your empirical findings. This section is sometimes also called the “empiracles” chapter. This section is usually pretty straightforward and technical, and full of details. Don’t shortcut this chapter.
• Discussion : This can be a tricky chapter, because it’s where you want to show the reviewer that you know what you’re talking about. You need to speak as a PhD versus a student. The discussion chapter is similar to the empirical/results chapter, but you’re building on those results to push the new information that you learned, prior to making your conclusion.
• Conclusion : Here, you take a step back and reflect on what your original goals and intentions for the research were. You’ll outline them in context of your new findings and expertise.

Tips for your PhD Thesis Format

As you put together your PhD thesis, it’s easy to get a little overwhelmed. Here are some tips that might keep you on track.

• Don’t try to write your PhD as a first-draft. Every great masterwork has typically been edited, and edited, and…edited.
• Work with your thesis supervisor to plan the structure and format of your PhD thesis. Be prepared to rewrite each section, as you work out rough drafts. Don’t get discouraged by this process. It’s typical.
• Make your writing interesting. Academic writing has a reputation of being very dry.
• You don’t have to necessarily work on the chapters and sections outlined above in chronological order. Work on each section as things come up, and while your work on that section is relevant to what you’re doing.
• Don’t rush things. Write a first draft, and leave it for a few days, so you can come back to it with a more critical take. Look at it objectively and carefully grammatical errors, clarity, logic and flow.
• Know what style your references need to be in, and utilize tools out there to organize them in the required format.
• It’s easier to accidentally plagiarize than you think. Make sure you’re referencing appropriately, and check your document for inadvertent plagiarism throughout your writing process.

Thesis Submission Checklist

INTRODUCTION All DrPH degree candidates at the Harvard Chan School are required to successfully complete and submit a thesis to qualify for degree conferral. This website provides information on the requirements for how to format your thesis, how to submit your thesis, and how your thesis will be distributed.  Please follow the submission and formatting guidelines provided here. Back to top

PREPARING TO SUBMIT THE THESIS The electronic submission of your thesis and the original Signature Page are due on the dates specified on the Harvard Chan School’s Academic Calendar Summary for each degree awarding period (November, March, and May). These items must be submitted using the ETDs @ ProQuest tool in order for the degree to be voted. No exceptions will be made to this rule. Back to top

Application for the Degree There are three degree granting periods: November, March, and May. To apply for graduation, students must complete the Application for Degree on the my.Harvard portal by the deadline posted on the Harvard Chan School’s Academic Calendar .

Deadline extensions are not possible. Students who miss the deadline must apply for the subsequent degree conferral date (November, March, or May). The student is responsible for meeting submission deadlines. Back to top

Oral Final Examination — Signature Page All Doctoral Committee members are required to sign the Signature Page at the time of the Doctoral Final Oral Examination indicating their final approval of the thesis.

A scanned copy of the Signature Page should appear before the title page of the PDF online submission of the thesis; no page number should be assigned to the Signature Page. The title on the Signature Page must read exactly as it does on the title page of the thesis. The Signature Page will be included in all copies of the thesis.

Click here for instructions on how to merge the Signature Page into the thesis PDF.

The Signature Page for DrPH students must be formatted as follows:

This Doctoral Thesis, [ Title of Doctoral Project ], presented by [ Student’s Name ], and Submitted to the Faculty of The Harvard T.H. Chan School of Public Health in Partial Fulfillment of the Requirements for the Degree of Doctor of Public Health , has been read and approved by:

______________________________________ (typed name below line – signature above)

________________________________________ (typed name below the line – signature above)

Date : [ Doctoral Project Official Approval Date (month day, year) ]

Back to top

ONLINE SUBMISSION OF THE THESIS  

ETDs @ ProQuest All DrPH candidates are required to submit a digital copy of the thesis to the Registrar’s Office as a PDF file via ETDs @ ProQuest by the deadline established for each degree conferral date. Theses must be submitted in their final format, as described in the section Formatting Guidelines . Students must check their formatting carefully before submitting. Formatting errors will prevent the students’ theses from being accepted and approved.

The online-submission tool can be found at:  http://www.etdadmin.com/hsph.harvard

A how-to video for submitting a thesis via ETDs is available on the Countway Library website .

ORCID ETDs @ ProQuest supports ORCIDs.  ORCIDs are persistent digital identifiers that link you to your professional activity.  You may register for an ORCID either before or during submission if you do not yet have one.  To do so, you may go here .

The Harvard Library ORCID page provides information about the value of having an ORCID iD and how Harvard plans to use ORCID data. Additionally, please visit the Harvard ORCID Connect site to connect your existing ORCID iD to Harvard University.

Harvard Author Agreement When submitting work through ETDs @ ProQuest, you will be consenting to the Harvard Author Agreement , which grants the University a non-exclusive license to preserve, reproduce, and display the work. This license, which is the same the Harvard Chan School faculty use under the School’s Open Access Policy, does not constrain your rights to publish your work subsequently. Back to top

Redaction Very few theses require redaction, which is the process of obscuring or removing sensitive information for distribution. ETDs @ ProQuest does support redacted versioning for these very rare cases where there is sensitive or potentially harmful material in the thesis (e.g., commercially sensitive information, sensitive personal data, risk of harmful retribution, etc.).

If your work is one such rare instance, then you may select the “I think I need to submit a redacted version of my thesis” on the file upload screen. You will then be prompted to contact the Office for Scholarly Communication, which will help you with your request. Back to top

Embargoes To forestall any potential challenges that a student may face in the publication process (e.g., if the candidate has a publication pending with a publisher or has previously published some of the content in the thesis and there is a publisher’s embargo that must be honored), the Harvard Chan School has instituted a default one-year embargo for submissions through ETDs @ ProQuest.   The embargo starts on the date of the thesis submission deadline. With an embargo, the full text of the thesis will be unavailable for view or download for a limited period of time.  The citation and abstract for the work, however, will be publicly available.

If a student would like to make her/his work available immediately by opting out of the embargo process, she/he may do so by selecting the No Embargo option during the submission process.

If, due to extenuating circumstances, a student is required to embargo part or all of their work beyond one year, she/he must request an extension during the submission process. An extension can be requested for up to two years. This request is subject to the approval of the student’s department chair(s) and the University Librarian.

Any embargo applied to the DASH version of the thesis will be applied to the Countway Library and Harvard Chan School department versions of the work.

Students do not need to take any action to remove an embargo.  The embargo will automatically be lifted in DASH at the end of the selected and approved period.  If a student would like to change the duration of his/her embargo request, then please contact the Registrar’s Office at [email protected] or 617-432-1032. Back to top

Surveys The School of Public Health is asked to participate in the Survey of Earned Doctorates. This is an annual census of research doctorate recipients in the United States.  Data collected from these surveys are used to make federal policy decisions regarding graduate education.

Students are required to complete the Survey of Earned Doctorates upon submission of their thesis. A Certificate of Completion will be sent to you, as well as to the Registrar’s Office.

Please click here to complete your survey.

DISTRIBUTION OF THE THESIS

Open Access For information on open access, we recommend the Office of Scholarly Communication’s (OSC) Director Peter Suber’s brief introduction . He has also written about providing open access to theses . The OSC has produced several videos of Harvard faculty and students discussing open access. Two may be of particular interest: the first features Professors Gary King and Stuart Shieber , and the second features a recent Harvard graduate, Ben Finio . Back to top

After Submission Once you have applied for your degree and submitted your thesis online, it is checked for compliance by the Registrar’s Office and, if accepted, is piped to the following downstream systems:

• DASH : Your work will be sent to DASH (Digital Access to Scholarship at Harvard), Harvard’s open access repository. Search engines index DASH, which means your work will be more discoverable and more frequently cited. You will be making DASH access decisions for your work at the point of submission. This will be the access copy of the thesis.
• HOLLIS : The metadata about your work will be sent to HOLLIS . This will make your work discoverable through the Harvard Library catalog.
• DRS2 : Your work will be stored in Harvard Library’s digital preservation repository, DRS2 . This will be the preservation copy of the thesis.

By default, theses will be made available through DASH one year after students submit their theses via ETDs @ Harvard for degree completion (see Embargoes ). DASH is operated by Harvard Library’s Office for Scholarly Communication and is the University’s central service for openly distributing Harvard’s scholarly output.

Note that any embargo applied to the DASH version of the thesis will be applied to the Countway Library and department versions of the work. Back to top

Bound Thesis Fee Currently we are not receiving bound thesis copies.  Doctoral students will not be charged bound thesis fees. Back to top

Additional Bound Copies Students may secure extra copies of their work for their own purposes.  These additional copies may be purchased through  Acme Bookbinding . or through ETDs @ ProQuest . Back to top

COPYRIGHT AND PUBLISHING CONSIDERATIONS

Understanding Your Copyright and Fair Use The Office for Scholarly Communication has created copyright-related resources for your reference.

The first addresses your copyrights and identifies some considerations when publishing (see “ Planning to publish? ”). It is important that you envision any future use you may like to make of your work. Any publishing contract you sign can affect your potential future uses, such as use in teaching, posting your work online on either a personal or departmental website, or any potential future publication. Before you sign a publication agreement, you can negotiate with a publisher to secure licensing terms that best suit your needs. It is important that you read any contract you sign and keep a copy for your own records.

The second resource discusses fair use (see “ Fair use ”), what it is, the laws that have determined its shape over time, and tips for ensuring that use of third-party material (including quotes, images, music, film, etc.) in your thesis is fair. Back to top

Copyright Registration Your work is copyrighted as soon as it is fixed in a tangible form. You are not required to register your copyright with the U.S. Copyright Office to enjoy protection of your work. However, if you choose to do so, you may register your work with the Copyright Office online . Back to top

Acknowledging the Work of Others Students are responsible for acknowledging any facts, ideas, or materials of others used in their own work. Students should refer to the statement on Academic Dishonesty and Plagiarism in the Harvard Chan School’s Student Handbook . Back to top

Use of Copyrighted Material A thesis is a scholarly work, and as such use of third party material is often essential. Fair use applies to the reproduction of any third party material, including your own previously published work, that you may use in your thesis.

If you have questions about copyright and fair use, please contact the Office for Scholarly Communication . Back to top

Steps for Using Published and To-Be Published Work When submitting an article for publication that you intend to use in your thesis, you should secure permission to do so (along with permission to reuse your own work as you would like) from your publisher in your publishing agreement. If the default contract does not let you retain these rights already, then you should use an author addendum to secure these rights (see “ Planning to publish? ”).

You may use your own previously published material as part of your thesis with the permission of the publisher. Again, refer to your publication agreement for details. If your contract does not specify these rights, then contact the publisher to negotiate this use. Back to top

FORMATTING GUIDELINES The following are instructions on how to format your thesis. If, after reading the instructions here, you have additional questions about the requirements, please contact the Registrar’s Office at (617) 432-1032; [email protected]. Back to top

Text   All text should be double-spaced on one side of the page with footnotes single-spaced. The font size should be at least 10 point, but no larger than 12 point.  The font and font size should be consistent throughout.  All text should be black. Back to top  |  Back to Formatting Guidelines

Margins The margins of the thesis must be 1 inch on all sides. Back to top  |  Back to Formatting Guidelines

Pagination Students’ theses must follow the pagination guidelines as illustrated below. It is customary not to have a page number on the page containing a chapter/paper heading. Drawings, charts, graphs, and photographs should be referred to as figures and should be numbered consecutively within the text of the thesis with Arabic numerals. Each figure should carry a suitable caption; e.g., Fig. 42. Arrangement of Experimental Equipment. Check pagination carefully and account for all pages.

All page numbers should be consecutive and centered at either the bottom or top of the page.

Abstract The abstract should not exceed 350 words. It should immediately follow the Title Page, and should state the problem, describe the methods and procedures used, and give the main results or conclusions of the research. The abstract should be double-spaced. The author’s name and the title of the thesis, as well as the name of the thesis advisor, should be included on the abstract page. The author’s name should be right justified, the title of the thesis centered, and “Thesis Advisor: Dr. ____________” should be left-justified at the top of the abstract page.

Thesis Advisor: Dr. [Advisor’s name]                                                    [Author’s name]

[Title of thesis]

           The text of the abstract, not to exceed 350 words, should be double-spaced.  The first line of each paragraph is indented.  Full justification of the text is not recommended.

Students will also be required to submit a text version of the abstract via the online-submission tool. Back to top  |  Back to Formatting Guidelines

Body of Thesis The thesis should consist of manuscripts suitable for publication in a scientific medium appropriate to the candidate’s field and/or approved reprints of the published work(s) (see Steps for Using Published and To-Be Published Work and Use of Copyrighted Material ).

Technical appendices should be added where necessary to demonstrate full development of the thesis material. Papers published under joint authorship are acceptable provided the candidate has contributed a major part to the investigation. The degree candidate is expected to be senior author on at least one of the papers. In the case of manuscripts published under joint authorship, the co-authors or the advisor may be consulted by the readers or the CAD to clarify the nature and extent of the candidate’s contribution. In addition to evaluating the quality and significance of the work, those responsible for accepting the thesis [the Department(s) and Doctoral Project Committee] may determine whether the format is suitable for publication in a scientific medium appropriate to the degree candidate’s field(s). Back to top  |  Back to Formatting Guidelines

Figures and Tables Figures and tables must be placed as close as possible to their first mention in the text. They may be placed on a page with no text above or below, or they may be placed directly in the text. If a figure or table is alone on a page with no narrative, it should be centered within the margins of the page.

Figures and tables referred to in the text may not be placed at the end of the chapter or at the end of the thesis. Figure and table numbering must be either continuous throughout the thesis or by paper (e.g., 1.1, 1.2, 2.1, 2.2). For example, there cannot be two figures designated in a thesis as “Figure 5.”

Headings of tables should be placed at the top of the table. While there are no specific rules for the format of table headings and figure captions, a consistent format must be used throughout the thesis. (See Citation and Style Guides )

Captions of figures should be placed at the bottom of the figure. If the figure takes up the entire page, the figure caption should be placed alone on the preceding page and centered vertically and horizontally within the margins. Each page receives a separate page number. When a figure or table title is on a preceding page, the second and subsequent pages of the figure or table should say, for example, “Figure 5 (Continued).” In such an instance, the list of figures or tables will list the page number containing the title. The word “Figure” should be written in full (not abbreviated), and the “F” should be capitalized (e.g., Figure 5). In instances where the caption continues on a second page, the “(Continued)” notation should appear on the second and any subsequent page. The figure/table and the caption are viewed as one entity and the numbering should show correlation between all pages. Each page must include a header.

Horizontal figures and tables must be positioned correctly and bound at the top, so that the top of the figure or table will be at the left margin (leave a 1 inch margin on the long edge of the paper above the top of the table).

Figure and table headings/captions are placed with the same orientation as the figure or table when on the same page. When on a separate page, headings/captions are always placed in vertical orientation, regardless of the orientation of the figure or table. Page numbers are always placed as if the figure were vertical on the page.

Figures created with software are acceptable if the figures are clear and legible. Legends and titles created by the same process as the figures will be accepted if they too are clear, legible, and run at least 10 or 12 characters per inch. Otherwise, legends and captions should be printed with the same font used in the text. Back to top  |  Back to Formatting Guidelines

Footnotes Footnotes are reserved for substantive additions to the text and should be indicated by an asterisk in the text. Extensive use of footnotes is not encouraged. The footnote should be placed at the bottom of the page. A horizontal line of at least two inches should be typed above the first footnote on any page. Footnotes should be placed so that at least one inch is left at the bottom of the page. Use single-spacing within footnotes. Back to top  |  Back to Formatting Guidelines

Bibliography To document the sources of information, a bibliography must be included at the end of the papers or thesis. References may be numbered or listed alphabetically. If references in the bibliography are numbered, then corresponding in-text references should be indicated by listing the number in parentheses after the name of the author.

Bibliographic Example:

23. Gibbs, C.S.: Filterable virus carriers. J. Bact., 23, 1932, 113.

In-Text Example:

“. . . as Gibbs (23) has stated.”

The initial number should be omitted if references are listed alphabetically.

Within any bibliographic section there should be consistency and adherence to an acceptable journal style for a bibliography. Each reference in the bibliography must contain the name of the author, title of the paper, name of publication, volume, date, and first page.

More than one publication by the same author in the same year should be indicated both in the bibliography and in the text by the use of underlined letters, etc., after the date of publication. The standard system of abbreviation used by the Quarterly Cumulative Index should be followed for the abbreviations of journal titles.

If students’ individual papers have different bibliographic styles, then it is not necessary to change the bibliographic style of one to match the other. Consistency within each bibliographic section is the most important element. Back to top  |  Back to Formatting Guidelines

Supplemental Material Supplemental figures and tables must be placed at the end of each chapter/paper in an appendix. If additional digital information (including text, audio, video, image, or datasets) will accompany the main body of the thesis, then it should be uploaded as supplemental material via the ETDs @ Harvard online submission tool.

Structuring your thesis

Time spent thinking about and planning how you will structure your thesis is time well spent. Start to organise the material that you have already written into folders relating to each chapter. The following techniques may help you to decide upon a structure.

• Discuss the structure with a colleague, explaining it as a continuous story you're trying to write 
• Use visual techniques like mind-mapping
• Create a storyboard for your thesis. This tells the ‘story' of the thesis in a small number of panels that mix text and pictures
• Sort index cards with key ideas into a coherent structure
• Use post-it notes with key ideas on a whiteboard to make connections with lines and colours.

Analysing existing theses is a good starting point to get an idea of typical structures in your field. Theses will usually contain most or all of the following sections:

• Acknowledgements
• Contents page(s)
• Introduction
• Literature review (sometimes within the introduction)
• Materials/sources and methods (can be part of every chapter if these are different per chapter)
• Themed topic chapters
• Discussion or Findings
• Conclusions
• Your publications

Once a rough structure is sketched out, it is a good idea to assign each chapter a likely word length and, if possible, a deadline for a first draft.

Writing preferences

People have different preferences in terms of writing. Think about the approach that will work best for you. For example here are two examples of writing preferences. 

Planning writers tend to have a highly structured approach to writing and if this is your approach you may find the following tips helpful.

• Under each chapter heading define a series of sections
• Break these into sub-sections and keep breaking these down until you are almost at the paragraph level
• You can now work methodically through this set of short sections
• Check completed sections or chapters agree with your plan

Generative writers prefer to g et ideas down on paper and then organise them afterwards. If this approach suits you try the following approach.

• Choose a chapter and just start typing
• Then you need to do some work to impose a structure
• Summarise each paragraph as a bullet point
• Use this summary to gain an overview of the structure
• Re-order the writing and strengthen the structure by adding sub-headings and revising what you have written to make the argument clearer

Reviewing your structure

As your research and writing develop you will want to revise and rework your structure. Try to review do this on a regular basis and amend plans for future chapters as you become more aware of what the thesis must contain.

How long is a PhD dissertation? [Data by field]

The final piece of the PhD journey is the PhD dissertation. It takes many years to accumulate enough original and new data to fill out a dissertation to the satisfaction of experts in your field. Interestingly, the PhD dissertation length and content vary significantly based on the field you are studying and the publishing conventions.

A PhD can be anywhere from 50 pages to over 450 pages long. This equates to between about 20,000 words to 100,000 words. Most PhD theses are between 60,000 and 80,000 words long excluding contents, citations and references.

A PhD thesis contains different sections including an introduction, methods, results and discussion, conclusions, further work, and references. Each one of these different sections will vary in length depending on the field of study and your particular topic.

Ultimately, a PhD dissertation should contain as many pages and words as it takes to communicate the results of your multi-year investigation.

It is very rewarding to see your thesis come together as you are writing day after day. When I was writing my PhD dissertation I wrote the sections separately and my heart filled with joy when I finally put them all together and compile them into a single PDF document.

Counting the pages should not be the way to determine a PhD dissertation’s value but it certainly helps when your thesis is starting to look substantial in thickness.

How many pages should a PhD dissertation be?

A PhD dissertation should contain as many pages and words as it takes to outline the current state of your field and provide adequate background information, present your results, and provide confidence in your conclusions. A PhD dissertation will also contain figures, graphs, schematics, and other large pictorial items that can easily inflate the page count.

Here is a boxplot summary of many different fields of study and the number of pages of a typical PhD dissertation in the field. It has been created by Marcus Beck from all of the dissertations at the University of Minnesota.

Typically, the mathematical sciences, economics, and biostatistics theses and dissertations tend to be shorter because they rely on mathematical formulas to provide proof of their results rather than diagrams and long explanations.

On the other end of the scale, English, communication studies, political science, history and anthropology are often the largest theses in terms of pages and word count because of the number of words it takes to provide proof and depth of their results.

At the end of the day, it is important that your thesis gets signed off by your review committee and other experts in the field. Your supervisor will be the main judge of whether or not your dissertation is capable of satisfying the requirements of a PhD in your field.

If you want to know more about how long a Masters’s thesis and PhD dissertation is you can check out my other articles:

Can a PhD dissertation be too long?

A PhD thesis should contain enough evidence and discussion to report on the most significant findings of your PhD research.

A PhD dissertation should not contain everything that you have done during your PhD. It should only include the data and information required to convince your PhD examining body that wraps up and tells the full story of particular lines of investigation.

Including random results, thoughts, or superfluous explanation can result in a dissertation that is unfocused. I have heard of music PhD is being described as too verbose and physical sciences PhD dissertations as being unfocused.

Therefore, a PhD thesis can be too long if the information it contains does not form a full and cohesive story.

One of my colleagues during their PhD removed an entire chapter from the thesis after writing it as the supervisor said that it needed more experiments to be a full story. They did not want to spend the next six months gathering the data and simply removed the chapter altogether.

How short can PhD dissertation be?

The shortest PhD dissertations are typically found in mathematics.

George Bernard Danzig was an American mathematical scientist who made contributions to industrial engineering and many other mathematical-related fields. An interesting miscommunication led to 1 of the shortest PhD theses ever.

In 1939 his professor wrote two problems on the blackboard and Danzig thought they were homeless assignments. He stated that they were harder than usual but handed in solutions to the surprise of the professor.

They were, in fact, open mathematical problems in statistics.

His professor said to bind the solution to the two problems together and submit them as his thesis – the total thesis length = 14 pages.

Obviously, most PhD theses and dissertations will be so much longer than that!

My PhD dissertation was 256 pages long. It was full of schematics, diagrams, and tables to demonstrate and communicate my findings.

I would say that most people’s PhD thesis experience will be closer to mine than Prof George Bernard Danzig’s.

Why PhD dissertations are typically so long

PhD dissertations are often over 200 pages long.

One of the primary reasons they are so long is that it is a single document that summarises many years of hard work. Also, summarising the research field to date and making sure that all of your references and citations are included so you avoid plagiarism will bolster the word count of the thesis dramatically.

Here are all of the reasons PhD dissertations tend to be so long.

Many years of work

PhD theses or dissertations contain many years of research and analysis.

In many of my YouTube videos I recommend that a PhD student work towards their PhD thesis by doing at least three hours of focused work every work day.

This amount of work quickly adds up.

Of course, not every bit of work makes it into the PhD dissertation but a lot of it does. It can be difficult to work out what to include or leave out of your thesis.

As a PhD student, I perfected the art of turning one experiment into many different types of grafts and schematics to fully explore the limits of my data. The graphs can take up a lot of space in your PhD thesis and, therefore, bolster the page count significantly.

In depth literature review

One of the most substantial parts of a PhD dissertation is the literature review.

The literature review can take up a huge portion of the early part of your PhD dissertation depending on the amount of data and publications in your field.

Writing an in-depth literature review requires just as much meticulous data analysis and searching as the central part of your dissertation.

Figures and schematics

Some fields end up producing a lot of figures and schematics.

My thesis had many full-page figures of atomic force microscopy experiments with much more explanation on subsequent pages.

As they say, a picture paints a thousand words and a dissertation can really benefit from having many schematics to highlight the important aspects of your findings.

References and citations

The recommended PhD dissertation word count from an institution or university does not include citations, references, or other thesis parts such as summary of abbreviations, table of figures, et cetera.

However, these components of your dissertation can take up many pages and add to the overall thickness of your PhD dissertation.

University formatting rules

University formatting rules will also dictate how you many pages your words take up.

I often get roasted on my YouTube channel for having doublespaced lines and wide margins. Unfortunately, this layout was dictated by my university before printing.

PhD dissertations often end up going into long-term storage and therefore, need to adhere to archival and standardised formatting rules.

Deep in the depths of the University of Newcastle, there is a copy of my thesis on a shelf. The formatting and binding rules mean that my thesis looks like everyone else’s.

Universities will often have their own requirements for PhD dissertation cover colour, quality, and type of paper. Even the quality of the paper can change the thickness of the PhD dissertation significantly.

PhD by publication

It is becoming increasingly common to submit a number of peer-reviewed papers bound together with supplementary information in between instead of a PhD dissertation.

The benefits of this to the researcher and university are:

• More early career peer-reviewed journals for career advancement
• an easier review process – they have already been peer-reviewed
• an early focus on publishing means better research outcomes for the researcher, supervisor, and Department.
• No mad rush at the end to finish a thesis
• continually writing peer-reviewed papers throughout your PhD helps with timely analysis and communication of results

Even though this option has been available to PhD students for a number of years, I have only known a handful of students actually submit their PhD via publication.

Nonetheless, having this option will suit some research fields better than others and lead to a more productive PhD.

Wrapping up

This article has been through everything you need to know about the length of a PhD dissertation and the common lengths of PhD dissertations for various fields.

Ultimately, there is no predefined length of a PhD.

A PhD thesis is as long as it needs to be to convince your examiners that you have contributed significantly enough to an academic field to be awarded the title of Dr of philosophy.

Mathematical and analytical theses tend to be shorter and can be as short as 50 pages (with one of the shortest being only 14 pages long). At the other end of the spectrum, PhD students in anthropology and history tend to produce the longest dissertations.

Rule of Three: advice on writing a PhD thesis

PhD students sometimes get the same bad advice on writing their thesis. I call this advice the Rule of Three . Typically, they get told that their thesis:

• Will take 3 months to write
• Should have 3 results chapters
• Should be 300 pages

These bits of advice have one thing in common: they are all wrong.

• If you have been organised (see below), it should not take 3 months to write a PhD thesis. It certainly shouldn’t involve leaving the lab 3 months before your hand-in date to write up.
• Theses can have one results chapter or they can have more. How many chapters depends on your project, and your results. Trying to make three results chapters out of one chapter ends up in a weak or overlong thesis.
• A thesis is like a piece of string and it will be as long as it needs to be. Aim for brevity and not producing a magnus opus (see below).

Disclaimer: what follows is some different advice. As with all “advice”, your mileage will vary. It is written for the people in my lab but likely applies to UK PhD students doing biomedical research.

Rule 1: aim for a thesis that is good enough

Who will read your thesis? Two people. Your examiners. OK, some parts – such as the Methods section – will be useful to future lab members (although with electronic lab notebooks this function is becoming redundant). Maybe your thesis will be downloaded by someone from the repository, but essentially, it will only be read by your examiners.

How long does an examiner spend reading your thesis? A few hours. One day maximum. They simply have no more time. Do you really want to spend three months of your life writing something that will be read for just a few hours by two people?

It’s for these reasons that spending too much effort writing a perfect thesis is a waste of time. It just needs to be good enough.

As well as being just good enough, it only needs to be long enough . A big mistake students make is to produce a really long thesis because they think that that is what theses should be (rule of 3). What happens is the examiner will receive the thesis, look at how many pages there are, subtract the bibliography, and their heart will sink if it is too long.

You might now be wondering: is writing a thesis a waste of time?

No, because you have to do it to get your PhD.

No, because you learn important writing skills. You also learn how to assemble a large document (it’s often how students learn to use Word properly or up their LaTeX game). It’s good training for writing papers and other technical documents down the line. Employers know this when they hire you.

But that is about it. So you just need to write something that is good enough to pass.

Rule 2: prioritise papers and the thesis will follow

Papers are the priority. They are more useful to you and to your PI. But this advice isn’t motivated by self-interest. If you go into the viva and the work in your thesis is already peer reviewed and published, it’s harder for the examiners to criticise it. At least, they will not approach your thesis with the question: is this work publishable? This is one criteria for passing your PhD, so demonstrating that it is publishable means you are (almost) there.

This was the one bit of advice I received when doing my PhD and it is still true today. OK, it is harder these days to get a first author paper published before you submit your thesis. However a preprint on bioRxiv before you begin writing will help you to prepare your thesis and will still tick the publishable box.

How long should it take to write your thesis?

There is tension here because you are at your most useful in the lab as you near the end of your PhD. One week of labwork now is worth one month (or more) earlier in your PhD. You are most valuable to your lab/PI/science/career at this point and keeping working in the lab will yield more rewards. But it won’t get your thesis written.

The first bit of writing is busywork and can be done around lab work. “Deep writing” and reading does need time away for most students.

If you have only collected data in the lab and not analysed it, if you’ve not presented your work very often, if you are disorganised… yes, it will take you a full three months to write your thesis.

All the folks in my lab are encouraged to get figures ready, analyse as they go and they also give regular talks. It should not take anyone in this position three months away from the lab to write their thesis.

Agreeing a timeline with your PI for when you begin writing is really important. Regular deadlines and a commitment to timely feedback from your supervisor make thesis writing easier. The discussion needs to be based on facts though. Often students want to budget a lot of time to writing, because of the rule of 3 or because they believe they are “bad at writing”. It helps to see some evidence. Writing draft chapters earlier in the PhD – which is a requirement at some universities – can reveal difficulties and weaknesses.

Reality check

If you hear the rule of 3 from everyone and your supervisor is giving you different advice. It might be time for a reality check. Have a look at past theses from the lab. How long were they? How many chapters? Information is good.

You can see that all theses are fewer than 300 pages in length, many substantially so. Four have three chapters and two have two. Although looking closer, two of the theses with three chapters use a results chapter as an expanded methods chapter.

Ultimately, the thesis is your work but you will get input from your supervisor. Regardless of what is written here or how many people tell you about the rule of 3, your supervisor will have their own ideas about how your thesis should be. Agreeing a sensible plan with them is the way to get started productively.

Getting started

This is not a comprehensive guide but in order to write a good enough thesis, you first need a plan.

• Make a figure list. This should be every single figure you can think of. You can cross off ones you don’t need later if they don’t fit or are insignificant.
• Plan the narrative. There is usually more than one way to put together the figures to make a thesis. Be prepared for this to change after you start writing! Sometimes the writing process reveals ways in which the narrative should be rearranged.
• How many results chapters? Start with the idea that you will have one. Does it need dividing? If yes, then what are the titles of the two chapters? If you have difficulty titling them you may need to split to a 3rd.

Now you have a plan. It’s time to get going.

Set some goals – but make them small. Having a goal of “I am going to complete my thesis” is too demoralising. You need to feel like you are making progress constantly to stay motivated. Break it down into smaller chunks. “I will finish this chapter by next Friday”. “I will write the cloning section this morning and then go for a walk”.

Write the materials and methods first . It’s the easiest bit to write because it is all technical writing with little wordcraft required. You can fit it around labwork. In fact, it is easier to write whilst in the lab because you can look up all the stuff you need. Importantly, it gets over the “blank page syndrome”.

Next get your figures together . This should already be done if you have been organised.

Then write the figure legends . You already have the title for each figure from your plan. All you need to do is describe each panel. Again, quite low energy writing required for this task.

Now write the results sections ! This is the same way that we put papers together. The results parts of the thesis are more extended but in principle you will guide the reader though the figures that you’ve made. Remember, you already have the legends written. So you are already partly on your way.

Time to regroup . At this point you can refine your plan for the introduction and check the rest of your plan still makes sense. Now is the time for some deep writing and reading.

The post title comes from “Rule of Three” by The Lemonheads.

How long does it take to write a PhD thesis?

My short answer is 68 days, but please read the detail below…

Bold resolutions: “Piled Higher and Deeper” by Jorge Cham www.phdcomics.com

As a PhD supervisor I have often been asked ‘How long do you think it will take me to write up my thesis?’ My answer always begins ‘It depends…’ We then continue the conversation with an audit of material already drafted that may contribute (in edited format) to the final thesis. These include the initial literature review from the first year transfer report, and posters, conference papers and journal articles presented and/or published from the on-going work.

For example third year PhD student John Mowbray , who is currently based within the Centre for Social Informatics (CSI) at Edinburgh Napier University , has a strong basis for his literature review chapter in the form of a conference paper delivered at CoLIS 2016 , which is due to be published in full in Information Research later this year. Similarly John’s fellow student Frances Ryan has already published an account of research design for her study. This paper will underpin the writing of her methods chapter.

Then we consider less formal sources, such as any discussions or debates that the student has documented publicly elsewhere, for example in blog posts. See, for instance Lyndsey Jenkins ‘ recent thoughts about the importance of research domain at http://lyndseyjenkins.org. These may well contribute to a section of Lyndsey’s methods chapter when she comes to write up her work in 2018.

The students also have ‘non-public’ material about their work that will be adapted for their theses. These include interim reports for their supervisors and/or other stakeholders. For example, last semester CSI PhD student Iris Buunk wrote a report on some of the empirical work that she has conducted for the body that gave her access to survey respondents. Handwritten ideas and remarks kept in notebooks over the course of PhD registration are also very valuable ‘private’ resources.

Once we have completed this audit, the challenge of transforming all the work completed to date into an 80,000 word thesis appears not to be so great – but of course, it still all needs to be done!

Records from writing up my own PhD have also recently served as another source for answering questions about preparing the main output of the doctoral study. I undertook my PhD part-time over a period of just over four years while working full-time. Throughout this period there were weeks when I could not progress my work at all. This was largely due to other commitments in intensive periods related to teaching such as the marking season towards the end of each semester. There were other times when it was much easier to devote myself to my PhD. For example, I took annual leave in University vacation time for this purpose (rather than went away on holiday). To guard against losing track of my PhD at times when I was too busy to devote any time to it I kept detailed notes of my progress. As a result of this, I know exactly how much time I spent writing up each chapter for the final version of the thesis. Although all PhD theses are different, the proportion of time on each type of chapter may be helpful to those who have resolved to submit their theses in 2017.

In total it took me 68 days to write up my thesis (NB 68 to write up the work, not 68 days to complete the PhD!) This is the equivalent of approximately 14 working weeks, assuming a five day week. It needs to be borne in mind, however, that I was a part-time student. In practice the writing up was done over the last seven months of the four and half years in which I worked on the entire doctoral study.

The largest portion of the writing-up time – around three quarters – was spent on the two chapters that related the findings of my research, and about a fifth on the discussion chapter. My literature review took very little time to write up (just 5 days) because I had already presented much of it in published form. The methods and conclusions chapters did not take very long either (3.5 and 2.5 days respectively) largely because their content was straightforward. My introductory chapter was very short at a page and a half and was thus drafted in just a couple of hours.

As might be deduced from the time allocations given above, I found the results and discussion chapters most heavy-going. The former was due to the quantity of empirical data to convert into a fluent account of the findings, and the latter because of the intellectual challenge of expressing the meaning of the findings and how the outcomes of my study represented an original contribution to the domain. However, once these two elements were ‘cracked’ it was a relatively easy task to pull all the other chapters together.

If you are reading this blog post as a PhD student in the later stages of your work, I would advise you to be prepared for the long haul of writing up your results and the discussion chapters, and ensure that you allocate a high proportion of your write-up time to these accordingly. It is also worth noting that I found that the closer I came to the target of completing my write-up, the more important it was for me to avoid other distractions. You cannot control for all of them (for example, illness), but I would caution against getting actively involved in anything that will take you away from your PhD at this intensive stage, such as planning a big event (for example, a major holiday, a house move, or a family wedding) or starting a new job.

If you are still in the early stages of your doctoral study, my first piece of advice is to plan your conference participation and journal paper publishing activity with the final thesis in mind. Be selective and strategic so that you prioritise engagement in external events that are valuable to the completion of your thesis and/or your future career. Each piece of work that you present externally should progress your study by encouraging you to write-up as you go along (for example in the form of a poster, a set of slides, a full paper), defend your ideas in person within your academic community, seek feedback on work completed to date, and solicit advice on the later stages. You should also be documenting any thoughts or ideas that may be valuable to writing up in a format that make sense to you, whether this be in a set of handwritten notes or in a more public format such as a series of structured blog posts.

Good luck to all those who will submit their theses in 2017!

Word limits and requirements of your Degree Committee

Candidates should write as concisely as is possible, with clear and adequate exposition. Each Degree Committee has prescribed the limits of length and stylistic requirements as given below. On submission of the thesis you must include a statement of length confirming that it does not exceed the word limit for your Degree Committee.

These limits and requirements are strictly observed by the Postgraduate Committee and the Degree Committees and, unless approval to exceed the prescribed limit has been obtained beforehand (see: Extending the Word Limit below), a thesis that exceeds the limit may not be examined until its length complies with the prescribed limit.

Extending the Word Limit

Thesis word limits are set by Degree Committees. If candidates need to increase their word limits they will need to apply for permission.

Information on how to apply (via self-service account) is available on the ‘ Applying for a change in your student status’  page. If following your viva, you are required to make corrections to your thesis which will mean you need to increase your word-limit, you need to apply for permission in the same way.

Requirements of the Degree Committees

Archaeology and anthropology, architecture and history of art, asian and middle eastern studies, business and management, clinical medicine and clinical veterinary medicine, computer laboratory, earth sciences and geography, scott polar institute, engineering, history and philosophy of science, land economy, mathematics, modern and medieval languages and linguistics, physics and chemistry, politics and international studies, archaeology and social anthropology.

The thesis is not to exceed 80,000 words (approx. 350 pages) for the PhD degree and 60,000 words for the MSc or MLitt degree. These limits include all text, figures, tables and photographs, but exclude the bibliography, cited references and appendices. More detailed specifications should be obtained from the Division concerned. Permission to exceed these limits will be granted only after a special application to the Degree Committee. The application must explain in detail the reasons why an extension is being sought and the nature of the additional material, and must be supported by a reasoned case from the supervisor containing a recommendation that a candidate should be allowed to exceed the word limit by a specified number of words. Such permission will be granted only under exceptional circumstances. If candidates need to apply for permission to exceed the word limit, they should do so in good time before the date on which a candidate proposes to submit the thesis, by application made to the Graduate Committee.

Biological Anthropology:

Students may choose between two alternative thesis formats for their work:

either in the form of a thesis of not more than 80,000 words in length for the PhD degree and 60,000 words for the MSc or MLitt degree. The limits include all text, in-text citations, figures, tables, captions and footnotes but exclude bibliography and appendices; or

in the form of a collection of at least three research articles for the PhD degree and two research articles for the MSc or MLitt degree, formatted as an integrated piece of research, with a table of contents, one or more chapters that outline the scope and provide an in-depth review of the subject of study, a concluding chapter discussing the findings and contribution to the field, and a consolidated bibliography. The articles may be in preparation, submitted for publication or already published, and the combined work should not exceed 80,000 words in length for the PhD degree and 60,000 words for the MSc or MLitt degree. The word limits include all text, in-text citations, figures, tables, captions, and footnotes but exclude bibliography and appendices containing supplementary information associated with the articles. More information on the inclusion of material published, in press or in preparation in a PhD thesis may be found in the Department’s PhD submission guidelines.

Architecture:

The thesis is not to exceed 80,000 words for the PhD and 60,000 words for the MSc or MLitt degree. Footnotes, references and text within tables are to be counted within the word-limit, but captions, appendices and bibliographies are excluded. Appendices should be confined to such items as catalogues, original texts, translations of texts, transcriptions of interview, or tables.

History of Art:

The thesis is not to exceed 80,000 words for the PhD and 60,000 words for the MLitt degree. To include: footnotes, table of contents and list of illustrations, but excluding acknowledgements and the bibliography. Appendices (of no determined word length) may be permitted subject to the approval of the candidate's Supervisor (in consultation with the Degree Committee); for example, where a catalogue of works or the transcription of extensive primary source material is germane to the work. Permission to include such appendices must be requested from the candidate's Supervisor well in advance of the submission of the final thesis. NB: Permission for extensions to the word limit for most other purposes is likely to be refused.

The thesis is for the PhD degree not to exceed 80,000 words exclusive of footnotes, appendices and bibliography but subject to an overall word limit of 100,000 words exclusive of bibliography. For the MLitt degree not to exceed 60,000 words inclusive of footnotes but exclusive of bibliography and appendices.

The thesis for the PhD is not to exceed 60,000 words in length (80,000 by special permission), exclusive of tables, footnotes, bibliography, and appendices. Double-spaced or one-and-a-half spaced. Single or double-sided printing.

The thesis for the MPhil in Biological Science is not to exceed 20,000 words in length, exclusive of tables, footnotes, bibliography, and appendices. Double-spaced or one-and-a-half spaced. Single or double-sided printing.

For the PhD Degree the thesis is not to exceed 80,000 words, EXCLUDING bibliography, but including tables, tables of contents, footnotes and appendices. It is normally expected to exceed 40,000 words unless prior permission is obtained from the Degree Committee. Each page of statistical tables, charts or diagrams shall be regarded as equivalent to a page of text of the same size. The Degree Committee do not consider applications to extend this word limit.

For the Doctor of Business (BusD) the thesis will be approximately 200 pages (a maximum length of 80,000 words, EXCLUDING bibliography, but including tables, tables of contents, footnotes and appendices).

For the MSc Degree the thesis is not to exceed 40,000 words, EXCLUDING bibliography, but including tables, tables of contents, footnotes and appendices.

The thesis is not to exceed 80,000 words including footnotes, references, and appendices but excluding bibliography; a page of statistics shall be regarded as the equivalent of 150 words. Only under exceptional circumstances will permission be granted to exceed this limit. Candidates must submit with the thesis a signed statement giving the length of the thesis.

For the PhD degree, not to exceed 60,000 words (or 80,000 by special permission of the Degree Committee), and for the MSc degree, not to exceed 40,000 words. These limits exclude figures, photographs, tables, appendices and bibliography. Lines to be double or one-and-a-half spaced; pages to be double or single sided.

The thesis is not to exceed, without the prior permission of the Degree Committee, 60,000 words including tables, footnotes and equations, but excluding appendices, bibliography, photographs and diagrams. Any thesis which without prior permission of the Degree Committee exceeds the permitted limit will be referred back to the candidate before being forwarded to the examiners.

The thesis is not to exceed 80,000 words for the PhD degree and the MLitt degree, including footnotes, references and appendices but excluding bibliography. Candidates must submit with the thesis a signed statement giving the length of the thesis. Only under exceptional circumstances will permission be granted to exceed this limit for the inclusion of an appendix of a substantial quantity of text which is necessary for the understanding of the thesis (e.g. texts in translation, transcription of extensive primary source material). Permission must be sought at least three months before submission of the thesis and be supported by a letter from the supervisor certifying that such exemption from the prescribed limit of length is absolutely necessary.

The thesis is not to exceed, without the prior permission of the Degree Committee, 80,000 words for the PhD degree and 60,000 words for the MSc or MLitt degree, including the summary/abstract.  The table of contents, photographs, diagrams, figure captions, appendices, bibliography and acknowledgements to not count towards the word limit. Footnotes are not included in the word limit where they are a necessary part of the referencing system used.

Earth Sciences:

The thesis is not to exceed, without the prior permission of the Degree Committee, 275 numbered pages of which not more than 225 pages are text, appendices, illustrations and bibliography. A page of text is A4 one-and-a-half-spaced normal size type. The additional 50 pages may comprise tables of data and/or computer programmes reduced in size.

If a candidate's work falls within the social sciences, candidates are expected to observe the limit described in the Department of Geography above; if, however, a candidate's work falls within the natural sciences, a candidate should observe the limit described in the Department of Earth Sciences.

Applications for the limit of length of the thesis to be exceeded must be early — certainly no later than the time when the application for the appointment of examiners and the approval of the title of the thesis is made. Any thesis which, without the prior permission of the Degree Committee, exceeds the permitted limit of length will be referred back to the candidate before being forwarded to the examiners.

The thesis is not to exceed, without the prior permission of the Degree Committee, 60,000 words including tables, footnotes, bibliography and appendices. The Degree Committee points out that some of the best thesis extend to only half this length. Each page of statistical tables, charts or diagrams shall be regarded as equivalent to a page of text of the same size.

The thesis is not to exceed 80,000 words for the PhD and EdD degrees and 60,000 words for the MSc and MLitt degrees, in all cases excluding appendices, footnotes, reference list or bibliography. Only in the most exceptional circumstances will permission be given to exceed the stated limits. In such cases, you must make an application to the Degree Committee as early as possible -and no later than three months before it is proposed to submit the thesis, having regard to the dates of the Degree Committee meetings. Your application should (a) explain in detail the reasons why you are seeking the extension and (b) be accompanied by a full supporting statement from your supervisor showing that the extension is absolutely necessary in the interests of the total presentation of the subject.

For the PhD degree, not to exceed, without prior permission of the Degree Committee, 65,000 words, including appendices, footnotes, tables and equations not to contain more than 150 figures, but excluding the bibliography. A candidate must submit with their thesis a statement signed by the candidate themself giving the length of the thesis and the number of figures. Any thesis which, without the prior permission of the Degree Committee, exceeds the permitted limit will be referred back to the candidate before being forwarded to the examiners.

The thesis is not to exceed 80,000 words or go below 60,000 words for the PhD degree and not to exceed 60,000 words or go below 45,000 words for the MLitt degree, both including all notes and appendices but excluding the bibliography. A candidate must add to the preface of the thesis the following signed statement: 'The thesis does not exceed the regulation length, including footnotes, references and appendices but excluding the bibliography.'

In exceptional cases (when, for example, a candidate's thesis largely consists of an edition of a text) the Degree Committee may grant permission to exceed these limits but in such instances (a) a candidate must apply to exceed the length at least three months before the date on which a candidate proposes to submit their thesis and (b) the application must be supported by a letter from a candidate's supervisor certifying that such exemption from the prescribed limit of length is absolutely necessary.

It is a requirement of the Degree Committee for the Faculty of English that thesis must conform to either the MHRA Style Book or the MLA Handbook for the Writers of Research papers, available from major bookshops. There is one proviso, however, to the use of these manuals: the Faculty does not normally recommend that students use the author/date form of citation and recommends that footnotes rather than endnotes be used. Bibliographies and references in thesis presented by candidates in ASNaC should conform with either of the above or to the practice specified in Cambridge Studies in Anglo-Saxon England.

Thesis presented by candidates in the Research Centre for English and Applied Linguistics must follow as closely as possible the printed style of the journal Applied Linguistics and referencing and spelling conventions should be consistent.

A signed declaration of the style-sheet used (and the edition, if relevant) must be made in the preliminary pages of the thesis.

PhD theses MUST NOT exceed 80,000 words, and will normally be near that length.

A minimum word length exists for PhD theses: 70,000 words (50,000 for MLitt theses)

The word limit includes appendices and the contents page but excludes the abstract, acknowledgments, footnotes, references, notes on transliteration, bibliography, abbreviations and glossary.  The Contents Page should be included in the word limit. Statistical tables should be counted as 150 words per table. Maps, illustrations and other pictorial images count as 0 words. Graphs, if they are the only representation of the data being presented, are to be counted as 150 words. However, if graphs are used as an illustration of statistical data that is also presented elsewhere within the thesis (as a table for instance), then the graphs count as 0 words.

Only under exceptional circumstances will permission be granted to exceed this limit. Applications for permission are made via CamSIS self-service pages. Applications must be made at least four months before the thesis is bound. Exceptions are granted when a compelling intellectual case is made.

The thesis is not to exceed 80,000 words for the PhD degree and 60,000 words for the MLitt degree, in all cases including footnotes and appendices but excluding bibliography. Permission to submit a thesis falling outside these limits, or to submit an appendix which does not count towards the word limit, must be obtained in advance from the Degree Committee.

The thesis is not to exceed 80,000 for the PhD degree and 60,000 words for the MSc or MLitt degree, both including footnotes, references and appendices but excluding bibliographies. One A4 page consisting largely of statistics, symbols or figures shall be regarded as the equivalent of 250 words. A candidate must add to the preface of their thesis the following signed statement: 'This thesis does not exceed the regulation length, including footnotes, references and appendices.'

For the PhD degree the thesis is not to exceed 80,000 words (exclusive of footnotes, appendices and bibliography) but subject to an overall word limit of 100,000 words (exclusive of bibliography, table of contents and any other preliminary matter). Figures, tables, images etc should be counted as the equivalent of 200 words for each A4 page, or part of an A4 page, that they occupy. For the MLitt degree the thesis is not to exceed 60,000 words inclusive of footnotes but exclusive of bibliography, appendices, table of contents and any other preliminary matter. Figures, tables, images etc should be counted as the equivalent of 200 words for each A4 page, or part of an A4 page, that they occupy.

Criminology:

For the PhD degree submission of a thesis between 55,000 and 80,000 words (exclusive of footnotes, appendices and bibliography) but subject to an overall word limit of 100,000 words (exclusive of bibliography, table of contents and any other preliminary matter). Figures, tables, images etc should be counted as the equivalent of 200 words for each A4 page, or part of an A4 page, that they occupy. For the MLitt degree the thesis is not to exceed 60,000 words inclusive of footnotes but exclusive of bibliography, appendices, table of contents and any other preliminary matter. Figures, tables, images etc should be counted as the equivalent of 200 words for each A4 page, or part of an A4 page, that they occupy.

There is no standard format for the thesis in Mathematics.  Candidates should discuss the format appropriate to their topic with their supervisor.

The thesis is not to exceed 80,000 words for the PhD degree and 60,000 words for the MLitt degree, including footnotes and appendices but excluding the abstract, any acknowledgements, contents page(s), abbreviations, notes on transliteration, figures, tables and bibliography. Brief labels accompanying illustrations, figures and tables are also excluded from the word count. The Degree Committee point out that some very successful doctoral theses have been submitted which extend to no more than three-quarters of the maximum permitted length.

In linguistics, where examples are cited in a language other than Modern English, only the examples themselves will be taken into account for the purposes of the word limit. Any English translations and associated linguistic glosses will be excluded from the word count.

In theses written under the aegis of any of the language sections, all sources in the language(s) of the primary area(s) of research of the thesis will normally be in the original language. An English translation should be provided only where reading the original language is likely to fall outside the expertise of the examiners. Where such an English translation is given it will not be included in the word count. In fields where the normal practice is to quote in English in the main text, candidates should follow that practice. If the original text needs to be supplied, it should be placed in a footnote. These fields include, but are not limited to, general linguistics and film and screen studies.

Since appendices are included in the word limit, in some fields it may be necessary to apply to exceed the limit in order to include primary data or other materials which should be available to the examiners. Only under the most exceptional circumstances will permission be granted to exceed the limit in other cases. In all cases (a) a candidate must apply to exceed the prescribed maximum length at least three months before the date on which a candidate proposes to submit their thesis and (b) the application must be accompanied by a full supporting statement from the candidate's supervisor showing that such exemption from the prescribed limit of length is absolutely necessary.

It is a requirement within all language sections of MMLL, and also for Film, that dissertations must conform with the advice concerning abbreviations, quotations, footnotes, references etc published in the Style Book of the Modern Humanities Research Association (Notes for Authors and Editors). For linguistics, dissertations must conform with one of the widely accepted style formats in their field of research, for example the style format of the Journal of Linguistics (Linguistic Association of Great Britain), or of Language Linguistic Society of America) or the APA format (American Psychology Association). If in doubt, linguistics students should discuss this with their supervisor and the PhD Coordinator.

The thesis is not to exceed 80,000 words for the PhD degree and 60,000 words for the MLitt degree, both excluding notes, appendices, and bibliographies, musical transcriptions and examples, unless a candidate make a special case for greater length to the satisfaction of the Degree Committee. Candidates whose work is practice-based may include as part of the doctoral submission either a portfolio of substantial musical compositions, or one or more recordings of their own musical performance(s).

PhD (MLitt) theses in Philosophy must not be more than 80,000 (60,000) words, including appendices and footnotes but excluding bibliography.

Institute of Astronomy, Department of Materials Science & Metallurgy, Department of Physics:

The thesis is not to exceed, without prior permission of the Degree Committee, 60,000 words, including summary/abstract, tables, footnotes and appendices, but excluding table of contents, photographs, diagrams, figure captions, list of figures/diagrams, list of abbreviations/acronyms, bibliography and acknowledgements.

Department of Chemistry:

The thesis is not to exceed, without prior permission of the Degree Committee, 60,000 words, including summary/abstract, tables, and footnotes, but excluding table of contents, photographs, diagrams, figure captions, list of figures/diagrams, list of abbreviations/acronyms, bibliography, appendices and acknowledgements. Appendices are relevant to the material contained within the thesis but do not form part of the connected argument. Specifically, they may include derivations, code and spectra, as well as experimental information (compound name, structure, method of formation and data) for non-key molecules made during the PhD studies.

Applicable to the PhDs in Politics & International Studies, Latin American Studies, Multi-disciplinary Studies and Development Studies for all submissions from candidates admitted prior to and including October 2017.

A PhD thesis must not exceed 80,000 words, and will normally be near that length. The word limit includes appendices but excludes footnotes, references and bibliography. Footnotes should not exceed 20% of the thesis. Discursive footnotes are generally discouraged, and under no circumstances should footnotes be used to include material that would normally be in the main text, and thus to circumvent the word limits. Statistical tables should be counted as 150 words per table. Only under exceptional circumstances, and after prior application, will the Degree Committee allow a student to exceed these limits. A candidate must submit, with the thesis, a statement signed by her or himself attesting to the length of the thesis. Any thesis that exceeds the limit will be referred back to candidate for revision before being forwarded to the examiners.

Applicable to the PhDs in Politics & International Studies, Latin American Studies, Multi-disciplinary Studies and Development Studies for all submissions from candidates admitted after October 2017.

Footnotes should not exceed 20% of the thesis. Discursive footnotes are generally discouraged, and under no circumstances should footnotes be used to include material that would normally be in the main text, and thus to circumvent the word limits. Statistical tables should be counted as 150 words per table. Only under exceptional circumstances, and after prior application, will the Degree Committee allow a student to exceed these limits. Applications should be made in good time before the date on which a candidate proposes to submit the thesis, made to the Graduate Committee. A candidate must submit, with the thesis, a statement signed by her or himself attesting to the length of the thesis. Any thesis that exceeds the limit will be referred back to candidate for revision before being forwarded to the examiners.

A PhD thesis must not exceed 80,000 words, and will normally be over 60,000 words. This word limit includes footnotes and endnotes, but excludes appendices and reference list / bibliography. Figures, tables, images etc should be counted as the equivalent of 150 words for each page, or part of a page, that they occupy. Other media may form part of the thesis by prior arrangement with the Degree Committee. Students may apply to the Degree Committee for permission to exceed the word limit, but such applications are granted only rarely. Candidates must submit, with the thesis, a signed statement attesting to the length of the thesis.

Thesis length.

Research theses have a word limit that you must comply with.

A PhD thesis should not exceed a total of 100,000 words in length (or 70,000 for most professional doctorates), including scholarly apparatus such as footnotes or endnotes, essential appendices and bibliography. A doctoral thesis should however, be concise. Examiners often criticise excessive length, which frequently indicates poor judgement.

When you submit, you will be asked to certify that your thesis falls within the relevant word limit.

In exceptional circumstances, the Dean—Wellington Faculty of Graduate Research may grant permission for you to submit a longer thesis. You will need to apply for permission to exceed the word limit well in advance of submission.

Word limits

• Doctor of Philosophy—100,000 words
• Doctor of Government—70,000 words
• Doctor of Health—70,000 words
• Doctor of Nursing—70,000 words
• Doctor of Midwifery—70,000 words
• Doctor of Education—70,000 words
• Doctor of Musical Arts—40,000 words

Writing the dreaded findings chapters of my PhD thesis

Researchers and Their Stories

Lyndsey Middleton

When I  returned from my internship at the Scottish government , my main task was to complete the three findings chapters of my thesis. The purpose of the chapters was to explain the findings of the interviews, focus groups, and the quantitative survey separately for each case study (i.e. one chapter for Scotland, one chapter for Finland, and one chapter for England). I drafted these in a decent time but then left them a little to focus on other elements of my PhD (i.e.  my conference presentation ,  and other things). I finally gave my supervisors a draft of my first case study—the largest of the three, in the hope that I would get some good feedback and then I would be able to edit down and that would be it. Oh how wrong I was!

The feedback from my supervisors was not the best, in terms of both content and the structure of the chapter itself. Whilst writing my chapter I had thought that it did not flow, but I was completely unprepared for what my supervisors said next. All three supervisors agreed that I needed to completely restructure the chapter so that the thematic analysis was at the forefront rather than the research questions directing what I wrote. By guiding the structure with the themes that emerged from participant interviews and focus groups, I would then be able to: (1) highlight the themes that emerged from participant discussions more clearly and (2) be able to discuss the findings in relation to the research questions in the discussion chapter that would follow. The statistics I had completed also did not quite work and I ended up having to re-analyse some of this with some help. The process of re-analysing a part of the survey responses meant that I learned a new statistical technique in the process (one which I have avoided for at least the last seven years!), and I am pleased to say that this was a small outcome of my work.

Initially, I was quite shocked by the comments as I did not think my chapter was that bad. However, after having gone through the process of redrafting the chapter it appears that all of my supervisors were on point with their comments and I finally saw the need to redraft from my supervisors’ perspective (they have done this before—a lot with other students—you know). So, after this supervision meeting, and a quick recap of the edits needed for my chapter (there were 2 A4 pages of comments!), I got down to work on the chapter. At first I struggled as I could not see the relationships between the comments from my participants nor could I see how the emerging themes linked. I therefore took a stand (sitting at my desk of course!) and figured that I could not do this alone. I used the help of my trusty pens (which I bought at the start of my PhD!), pencils, coloured paper, and highlighters to help me plan out (visually) what I hoped to see from my data.

The process of visually representing the relationships on paper started to help my findings finally sink in. I was able to write down the overarching theme (e.g. leadership or organisational culture) and then pinpoint (from my data) how this theme influences innovative work behaviour as well as how the themes interlink. You can see from the images in this blog post that I used many colours of my trusty pens to highlight the elements of the theme, the particular process of innovative work behaviour it related to (e.g. idea creation, championing, recognition), and then whether the quotations emphasise that individual employee or the collective nature of innovation. These were the most important things I needed to emphasise in my findings chapter to pull it all together and decipher what it means.

When it came to actually editing/rewriting the chapter (the debate still goes on…) this also took longer than I thought. I needed to edit my style of writing slightly and tackle my issues of writing as I speak. The  Mackem  in me tells me that my style of speaking (I found the phonology and grammar sections of this Wiki page rather amusing) is not the way to go in your thesis writing if you want to create something decent to submit. I therefore had to make sure I corrected my tenses, referred directly to my participant quotes, and made explicit references to innovative work behaviour in the quotations and writing of the work. By doing so, it is hoped that the readers of my chapter can easily draw conclusions from what I am saying and this will guide them through to my discussion chapter (I hope). And I can leave the lovely pronunciation of specific words from my accent to be discovered as part of my viva.

So, in my own opinion, it is quite hard to write a PhD thesis, and the process of writing/editing chapters is far more complex than I had ever imagined. Students do not really have a solid example of exactly how it should be structured and set. Instead, we can access resources to help us along the way. For example, I downloaded examples from trusted resources and tried to get an understanding of how findings chapters ‘should be’ structured. In doing so, I probably made things worse as I saw the variety of different structures and writing types out there. I also saw the vast amount of PhD theses that focus on some element of my work but I am yet to come across one which focuses on the specific behaviour of employees just like mine. I also asked some of our current PhD students (those nearer to the finish line than me) how they progressed with theirs, and I was given some great advice too. Not only did these students give me information and advice on how to structure different things, they also pointed me in the right direction as to where/who could help when I needed it. I often wonder why there are not more lectures/lessons on how to physically write a thesis and I suppose it is because of the potential impossibility of that challenge (the lectures, not the thesis writing). We can be taught about the formatting and what a thesis should look like, but the finer details I suppose are down to the individual student with the support of their supervisors in how they wish to academically speak.

I also once got asked what I (at that point in time) felt the hardest part of a PhD was and I have completely changed my mind on this now. The hardest part of a PhD thesis is this: writing your little heart out until you can physically write no more to find out that it needs a lot more work does suck but at the same time, I have been assured that this is all part of the process (by literally everyone—other students, supervisors and all).

Only two more findings chapters to edit…

How to Write a Perfect Discussion Chapter for a PhD Thesis

Discussion chapter of a PhD thesis focuses on explaining and analyzing what you have researched, presenting how it is associated with the existing literature. It is also a place for argument supporting your entire discussion. We often find that people seek thesis writing help from experienced editing and proofreading services to prepare a flawless PhD discussion chapter. However, following 9 essential tips can help you design a perfect PhD thesis with an excellent discussion chapter.

This article provides 9 effective tips for writing a flawless discussion chapter for a PhD thesis. To give you an opportunity to practice proofreading, we have left a few spelling, punctuation, or grammatical errors in the text. See if you can spot them! If you spot the errors correctly, you will be entitled to a 10% discount.

Writing a flawless PhD thesis requires much more than only subject matter expertise. It requires expertise, experience, and in-depth thinking, along with sharp intelligence. Though most students add a discussion chapter in their thesis or dissertation, many of them end up messing up the essay or missing out the central issues.

A discussion chapter in a PhD thesis is a place where you have the chance to delving into the analysis, importance, and relevance of your research. This section focuses on explaining and analyzing what you have researched, presenting how it is associated with the existing literature. It is also a place for argument supporting your entire discussion. We often find that people seek thesis writing help from experienced editing and proofreading services to prepare a flawless PhD discussion chapter. However, the following 9 essential tips can help you design a perfect PhD thesis with an excellent discussion chapter.

1. Understand the objective of your PhD thesis

Before setting out to conduct a PhD thesis, researchers design and plan a study with objective(s) in mind. Such objectives inform how the dissertation is conducted. For example, no researcher would just commence by administering questionnaires or setting up laboratory equipment without an objective. It also informs the questions and necessary procedures to undertake. To write a well-conveyed discussion section in PhD thesis, the author must review and ascertain whether the conducted study addressed these objectives. It takes the understanding of the objective to assess the achievement of the objective clearly. Based on the assessment, the author finds the direction of his discussion. The comprehension of this objective is critical to crafting a focused discussion section in scholarly writing.

2. Determine a clear structure

The first step in organizing a perfect discussion chapter for a PhD thesis is to divide them into separate sections that move from a particular result to implications. However, depending on your PhD thesis topics, you may utilize the followings:

Analyze and summarize your main findings.

Evaluate how the results reflect the literature review.

Show if the discussion impacts the original hypothesis and, if yes, how it affects your hypothesis.

3. Usage of grammar and tense

The proper usage of grammar and tense is a key to a seamless PhD thesis. The improper use of grammar and tense can have the worst impact on the entire dissertation, along with the discussion chapter . Depending on the context, the usage of past and present tense should be made. When you are referring to specific data, the present tense can be used. For instance, when the light increases, speed decreases. However, while summarizing the result or concluding something, past tense can be used. For example, between 2013 and 2016, the number of car accidents decreased visibly. However, depending on the context, you can combine two tenses. Also, bear in mind that different manuals might require different tenses.

The tense adopted by the study should be uniform. Try to write the discussion chapter of your PhD thesis in the required tense format of your guideline. For instance, The  APA Publication Manual  provides suggestions on which verb tense is appropriate for various sections of a thesis:

Past tense or present perfect tense for the literature review and "the description of the procedure if the discussion is of past events."

"Use past tense to describe the "

"Use the present tense to discuss the implications of the results and to present the conclusions. By reporting conclusions in the present tense, you allow all readers to join you in deliberating the matter at hand."

As much as possible, try to be consistent with your chosen verb tense within a section as doing so "can help ensure smooth expression."

It is always best to check with your manual to get their opinion on the best approach for your thesis.

4. Referring to hypotheses and literature review

The primary purpose of referring to the literature review is to contextualize your discussion chapter as a part of the debate. For instance, suppose you introduce a theory claiming that speed cameras have zero effect on a road’s fatalities. You need to describe how your findings relate to this assumption. The same applies while making a hypothesis. Never forget this fact while discussing your results.

5. Evaluate your results and compare them with existing studies

While writing the discussion chapter of your PhD thesis, you need to analyze your results rather than just simplifying it. Don’t forget to do complete research on if your results agree or conflict with the previous studies.  You need to evaluate if there are any differences and, if yes, what the differences are. Comparing the development with existing studies helps your research to connect any existing debate. It also offers a solid base of conclusions.

In a well-written discussion chapter of a PhD thesis, an author should compare his/her findings with those of other studies reported in the literature. This aspect is different from a literature review in the sense that the author has data at hand to compare, as against the general overview made about a thesis’s objectives prior to the investigation. In comparing, the author is able to pronounce the authenticity of the results, especially when similar procedures were used in other studies. Any differences in findings can be explained using the different peculiarities between the author’s study and others. If this consideration is carefully made and implemented, the author may likely find evidence-based explanations for his/her findings. Even for novel findings, an author may still find relevant literature that formed the rudiments of the present study to discuss the progress, contribution, and novel dimension of the study. 

6. Why should the findings of your PhD thesis matter?  

After discussing the study results, the author, as part of his goal, must propose the impact of the study’s findings on the problem that informed the idea of the thesis. The reader will be better served if the author describes a roadmap for solving the problem based on the findings. Depending on the nature of the problem, an author may propose solutions to affect policy, behavioral change, or conventional practice. Only after making this contribution will a discussion section expose readers to the specific and general impacts of a PhD thesis.

7. Understand the limitation of your research

It is one of the most important things to evaluate when writing a discussion chapter for your PhD thesis. The discussion chapter of your research paper should involve some acknowledgment of the study limitations. Suppose you have critically assessed similar studies in the literature review; you are free to compare your work against their weakness or strength.

8. Don’t be afraid to be unique

The focus on research may change and evolve with time if you are working on a long-term project. The key to adjusting the focus on the literature review is to reflect these changes. Suppose you may find that specific themes are more prominent than others; it is helpful if you review your literature review and tweak them to emphasize the themes. Never be afraid to be unique to bring the changes.

9. Don’t forget to avail a professional thesis editing and proofreading service

Last but not least, you can seek assistance from professional editing and proofreading services. Taking PhD thesis help from professional editing and proofreading services doesn’t only facilitate the writing process but also helps you execute a flawless PhD thesis with a well-formed and informative discussion chapter.

Therefore, as a student, especially for the ones getting higher education, it is needed for you to learn this way of writing and adopt it.

Some essays use logical and factual data to sustain their claims. They are known as argumentative essays and form a significant proportion of all essays written by scholars and students during their academic tenure.
