Typical Thesis Lengths by Degree and Subject

First identify what your university calls the project

The same word can refer to different degrees. In the United States, a thesis is usually the research project completed for a master’s degree, while a dissertation is the larger project submitted for a doctorate.

The pattern is often reversed in the United Kingdom and much of Europe. A dissertation may be an undergraduate or master’s project, while a thesis is commonly submitted for a PhD. Australia generally follows the British use, although individual programs may use dissertation for some professional doctorates. Canadian universities use both systems.

This distinction matters. A search result saying that a thesis should be 80,000 words may be discussing a British PhD thesis, not a US master’s thesis.

Use the name and limit printed in your own department’s handbook. Check the regulations for your degree, department, and year of enrollment rather than relying on another university’s guidance. Rules can differ between departments at the same institution.

If the handbook is unclear, ask these questions before planning chapters.

• Is the stated figure a target or a maximum?
• Is there a permitted percentage above or below it?
• Which sections are included in the count?
• Are article-based and traditional theses governed by different rules?
• Does your supervisor expect a length inside the formal maximum?

Written confirmation from the graduate coordinator is useful when a handbook and supervisor appear to give different answers.

Typical word counts by level and country

Start with degree level. A 12,000-word undergraduate project and an 80,000-word doctoral project may both be called a thesis, depending on where you study.

The ranges below are planning bands, not universal limits. Your university’s published regulations take priority.

Degree or project	Typical word count
Undergraduate research thesis	8,000 to 20,000 words
Undergraduate honors thesis	12,000 to 25,000 words
Taught master’s dissertation	10,000 to 20,000 words
Research master’s thesis	20,000 to 50,000 words
Professional doctorate dissertation	40,000 to 80,000 words
Traditional PhD thesis	70,000 to 100,000 words
Article-based PhD thesis	40,000 to 80,000 words, plus or including published papers

Country changes both the terminology and the expected scale.

Country or system	Undergraduate level	Master’s level	Doctoral level
United States	10,000 to 20,000-word honors thesis	20,000 to 50,000-word thesis	70,000 to 100,000-word dissertation
Canada	10,000 to 20,000-word honors thesis	20,000 to 50,000-word thesis	70,000 to 100,000-word thesis or dissertation
United Kingdom	8,000 to 15,000-word dissertation	10,000 to 20,000-word dissertation	70,000 to 100,000-word thesis
Germany	8,000 to 15,000-word bachelor thesis	15,000 to 30,000-word master thesis	Varies widely by subject and thesis format
Netherlands	6,000 to 15,000-word bachelor thesis	12,000 to 25,000-word master thesis	Often article-based, with institutional rules
Australia	12,000 to 20,000-word honors thesis	20,000 to 40,000-word thesis	70,000 to 100,000-word thesis

Page counts are less reliable because margins, spacing, figures, and reference styles alter the result. At 250 to 300 words per page, a 20,000-word thesis contains roughly 67 to 80 pages of main text. An 80,000-word doctoral thesis contains about 267 to 320 pages before front matter, references, and appendices are added.

Treat a maximum as a ceiling. If the rule says no more than 20,000 words, submitting 22,000 words can create an examination or administrative problem even when the extra material is strong.

How to split the word count across chapters

A large total becomes easier to manage once each chapter has a working allowance. The allocation should reflect your research design rather than an automatic formula, but percentages help prevent the literature review from consuming half the available space.

Consider a 20,000-word master’s thesis based on interviews. One workable chapter plan looks like this.

Chapter	Share	Word allowance
Introduction	9 percent	1,800 words
Literature review	20 percent	4,000 words
Methodology	12 percent	2,400 words
Findings	22 percent	4,400 words
Discussion	28 percent	5,600 words
Conclusion	9 percent	1,800 words
Total	100 percent	20,000 words

The introduction establishes the research problem, scope, questions, and chapter structure. It does not need to present every source you have read. The literature review explains the scholarly debate and identifies the gap your project addresses.

A 2,400-word methodology chapter is enough to describe the sample, data collection, analytical procedure, ethical treatment, and limitations in a modest interview study. A more technical experiment might need additional space. A humanities thesis may replace the standalone methodology chapter with a shorter discussion in the introduction.

Findings and discussion can be separate or combined. Separate chapters work well when you need to report a substantial body of results before interpreting them. Combined analytical chapters often suit history, literature, law, and qualitative social research because evidence and interpretation need to remain close together.

Build some flexibility into the first draft. If your final limit is 20,000 words, aim for an initial complete draft of about 18,000 to 19,000 words rather than filling every available line. You will need room for transitions, clarification, and evidence requested by your supervisor.

What counts toward the word limit

Universities do not apply one shared counting method. Some count nearly everything between the introduction and conclusion. Others exclude tables, footnotes, or material placed in designated appendices.

Sections commonly included are listed below.

• Introduction and conclusion
• Literature review
• Methodology
• Findings and discussion
• Direct quotations
• In-text citations
• Chapter notes or footnotes in many programs
• Table and figure captions in some programs

Sections commonly excluded include the following.

• Title page
• Declaration and acknowledgments
• Table of contents
• Lists of tables and figures
• Bibliography or reference list
• Appendices

The abstract is sometimes counted and sometimes excluded. The same uncertainty applies to words inside tables, translated extracts, mathematical proofs, computer code, and footnotes. An appendix may also have its own page or word limit even when it is excluded from the main count.

Do not move essential analysis into an appendix simply to meet the limit. Examiners usually expect the main text to contain the evidence and reasoning needed to support the conclusion. Appendices are better suited to interview schedules, full data tables, survey instruments, archival lists, code, and supplementary calculations.

Check how your word processor counts footnotes, text boxes, captions, and tables. Microsoft Word’s displayed total may not match the method specified by your department, especially when the regulations exclude particular sections.

How thesis length differs by discipline

Subject conventions shape the size and structure of the final document. A mathematics thesis may devote several pages to one proof and use relatively few words. A history thesis may need thousands of words to establish context, evaluate archives, and compare interpretations.

These broad ranges show how discipline can affect planning.

Discipline	Master’s project	Doctoral project
History and related humanities	25,000 to 50,000 words	80,000 to 120,000 words
Literature and cultural studies	20,000 to 40,000 words	70,000 to 100,000 words
Social sciences	15,000 to 40,000 words	60,000 to 100,000 words
Law	15,000 to 40,000 words	70,000 to 100,000 words
Laboratory sciences	15,000 to 35,000 words	40,000 to 80,000 words
Engineering and computing	15,000 to 40,000 words	40,000 to 80,000 words
Mathematics	15,000 to 30,000 words	30,000 to 70,000 words
Creative practice	10,000 to 30,000-word commentary	20,000 to 50,000-word commentary plus creative work

Humanities projects tend to be longer because the prose itself carries much of the evidence and analysis. Historians may need extended archival context. Literature researchers often conduct sustained readings of several primary texts.

Science and engineering theses can be shorter in words while remaining substantial in content. Equations, diagrams, datasets, experimental results, and technical appendices may occupy many pages without adding much to the word count.

Article-based doctorates require another calculation. A candidate might submit three published or publishable papers with an introduction, literature synthesis, linking discussion, and conclusion. Some universities include the papers in the formal count, while others impose limits only on the connecting material.

Creative practice degrees pair a portfolio, performance, film, composition, or other work with a written commentary. The written component may be much shorter than a traditional thesis because the creative work carries part of the research contribution.

How long thesis writing takes

The time needed depends on what you mean by writing. Drafting chapters is only one part of the process. Topic approval, ethics review, data collection, archival work, analysis, supervisor feedback, formatting, and revision can take longer than the first draft.

Project	Common working period
Undergraduate thesis	8 to 16 weeks
Honors thesis	4 to 9 months
Taught master’s dissertation	3 to 6 months
Research master’s thesis	6 to 18 months
PhD thesis drafting and revision	12 to 24 months
Full PhD research and submission	3 to 7 years

A 20,000-word master’s thesis completed over 16 weeks requires an average of 1,250 finished words per week. That does not mean writing exactly 1,250 words every week. Early weeks may be spent reading and collecting data, while later weeks produce several thousand words of draft material.

A practical 16-week schedule might reserve four weeks for refining the question and literature, four for data collection or primary-source analysis, five for drafting, and three for revision and formatting. Ethics approval must begin earlier if your research involves participants.

Plan backward from the submission date. Leave at least two weeks for references, captions, cross-checking, file conversion, and proofreading. If your supervisor needs two weeks to comment on a chapter, do not schedule that feedback three days before submission.

Revision deserves its own block. Cutting 3,000 words from an overlong draft can take longer than producing those words because you must preserve the argument while removing repetition, background, and weak examples.
