How Long Is a Dissertation? Full Word Count Breakdown

If you ever see a 400-page dissertation sample on your school’s website, you’ll feel like you don’t need a degree that much. Luckily, it’s an extreme case of a doctoral dissertation, and your project will likely be much more manageable.

So, how many words is a dissertation? How long is each part of the dissertation supposed to be? And which parts of the manuscript do not count toward the final length? In this post, we’ll share all the answers to give you a clear idea of how much more you need to write to finish your dissertation.

How Long Is a Dissertation by Type?

Naturally, undergrad and postgrad requirements can’t be the same. So, let’s look at the average dissertation length for every academic level.

Disclaimer: We share estimated average dissertation length, but you should always check your program’s requirements first. For example, here are the dissertation length requirements for Columbia University and Harvard Graduate School of Arts and Sciences.

Undergraduate Dissertation Length

Undergraduate dissertations are between 8,000 and 15,000 words. That’s 30 to 60 pages. In this case, the overall page count includes the title page, abstract, acknowledgements, table of contents, references, and other elements.

Master’s Dissertation Length

A master’s dissertation is 18,000 to 30,000 words. In some fields, they can reach 50,000 words. That’s 72 to 120 pages (200 pages in extreme cases). Considering postgraduate programs always involve independent research, this length should be sufficient to cover methodology, results, and discussion.

PhD Dissertation Length

How long is a doctoral dissertation? It’s 50,000 to 100,000 words or 200 to 400 pages. Although study results and discussion will be the largest part of the manuscript, the literature review and methodology will also be extended to cover the dissertation’s broad scope.

Dissertation Parts: Estimated Length

We won’t go into detail about the dissertation structure. Instead, we’ll share rough word count estimates for each section to help you plan your writing and avoid unnecessary bloating.

Abstract

Average length – 1 page, 150 to 250 words.

Most universities have strict abstract requirements. Check them before writing the abstract, and don’t confuse it with an executive summary. It should summarize all sections of your paper in one paragraph and provide a list of keywords.

Introduction

Average length – 1 to 5 pages.

Briefly introduce the context of your study and present your research question and objectives. The final length will depend on your academic level. Undergraduate dissertations may sometimes combine the introduction with the literature review. Doctoral dissertation introductions can span several pages and require a specific layout.

Literature Review

Average length – 15% to 20% of the dissertation’s word count.

That’s from 6 to 80 pages, depending on your academic level and research scope. The more sources you collect and analyze, the longer this section will be. You can order this section chronologically, thematically, or methodologically to keep it cohesive and understandable.

Methodology

Average length – 15% to 20% of the dissertation’s word count.

If you’re working on new or unique research methods for your Master’s or PhD dissertation, this section may be even longer, taking up to 100 pages of your manuscript. You can keep its length manageable by summarizing standard procedures without going into detail and providing relevant links to credible sources.

Results

Average length – 20% to 25% of the dissertation’s word count.

The core of your study should take the largest part of your dissertation. However, you don’t need to include every raw data point in this section to keep the length under control. It’s best to present the results of statistical data analysis and visualize your data using tables or diagrams. To keep this section readable, you can move the largest data sets, tables, and figures to the appendices.

Discussion

Average length – 15% to 25% of the dissertation’s word count.

Interpreting research results is equally important, and should be as thorough as their presentation. Remember that this section should also cover the theoretical and practical implications of your study, as well as implementation recommendations. You should also analyze the limitations of your research and suggest avenues of future study. This will all take a significant portion of your paper (at least 30 pages in a PhD manuscript).

Conclusion

Average length – 1 to 5 pages.

Like a reverse introduction, the conclusion is relatively short. It summarizes the paper's main sections, focusing on the research results and their discussion without repeating them verbatim. Reading the conclusion should be sufficient for anyone unfamiliar with your work to understand your primary achievements.

References

Average length – 1 to 10+ pages.

It’s impossible to estimate the exact length of your reference list without knowing how many sources you use. On average, one page fits around 15 properly formatted sources. So, if you only cite 10 articles, your references should fit on one page. For a doctoral dissertation with 200 sources, the reference list will exceed 10 pages.

Important: Learn whether the reference list counts toward your overall manuscript length. Some programs exclude references and appendices from the word count, so you may need to extend the body of your dissertation.

Acknowledgments

Average length – 1 page.

It’s an optional section, but skipping it is considered in poor taste. One page is the accepted limit, which is more than enough to thank everyone in your social and professional circles who helped you complete your dissertation. Similar to the reference list, acknowledgements are usually excluded from the overall word count.

Appendices

Appendices are optional, so there are no word count requirements. Since they usually don’t count toward your overall page count, you can include as many or as few as you want. Just make sure they're relevant to your study.

Final Thoughts

So, how long does a dissertation have to be? As you see, there’s no easy answer. The ultimate page and word count depends on your academic level, field of study, and (most importantly) your school requirements.
