How to Write a Thesis: Structure, Planning and Chapters

How to frame a research question, the standard thesis chapters and what each must do, a planning timeline, an example abstract and a final checklist.

Updated October 2026 · 5 min read

To write a thesis, start with one focused research question, find the gap in the literature, choose a fitting method, then report and discuss your findings in chapters that build on each other.

The same fundamentals apply to a master's thesis and an undergraduate dissertation. This page covers the research question, the standard structure, a planning timeline, how to work with your supervisor and the mistakes that cost most time.

The Thesis in One Paragraph

A thesis answers one guiding question with a defensible argument. The introduction sets out the question and why it matters; the literature review shows the gap; the methodology explains how you investigated; the results and discussion report and interpret what you found; and the conclusion answers the question and names the contribution and limits.

Start with a Focused Research Question

Everything hangs on the question. It must be narrow enough to answer in your timeframe and significant enough to matter to your field.

Too broad: "How does social media affect mental health?"

Narrower: "How does social media use affect anxiety in university students?"

Focused: "Is time spent on image-based platforms associated with social anxiety among first-year undergraduates at one UK university?"

The focused version names the variable, the population and the setting. You can see what data you would need and how you might collect it.

Standard Thesis Structure

Chapter names vary by discipline, and some fields combine results and discussion. This is the most common empirical structure.

ChapterWhat it doesRough share
AbstractSummarizes question, method, findings and contributionOne page or less
IntroductionQuestion, background, significance and a roadmapAbout 10 percent
Literature reviewMaps the debate and identifies the gapAbout 20 to 25 percent
MethodologyExplains and justifies how you investigatedAbout 15 percent
Results or analysisPresents what you foundAbout 20 percent
DiscussionInterprets findings against the literatureAbout 20 percent
ConclusionAnswers the question; contributions, limits, future workAbout 5 to 10 percent

Theoretical and humanities theses often replace methods and results with thematic chapters, each developing part of the argument. Check your department's handbook.

What Each Chapter Must Do

Literature Review

Organize the review by theme or debate, not as a list of summaries. Each section should show what is known, where scholars disagree and what remains unanswered, leading to the gap your question fills.

Methodology

Explain your design, sample, data collection and analysis, and justify each choice in relation to the question. Address ethics approval and the limits of your approach.

Results and Discussion

Report findings plainly in the results, using tables and figures where they help. Save interpretation for the discussion, where you compare findings with the literature and explain what they mean.

Plan the Project Backwards

StageTypical timing in a one-year master's
Question and proposalMonths 1 to 2
Literature review draftMonths 2 to 4
Ethics approval and data collectionMonths 3 to 6
Analysis and resultsMonths 6 to 8
Discussion and conclusionMonths 8 to 9
Revision, abstract and formattingFinal month or more

Work backwards from the deadline, set a milestone for each chapter and leave a generous block at the end for revision and formatting. Editing always takes longer than expected.

Working with Your Supervisor

Your supervisor is your most useful resource, but meetings are short. Arrive prepared so each one moves the project forward.

  • Agree a meeting schedule and deadlines early.
  • Send drafts ahead of meetings with specific questions.
  • Keep a record of the advice you receive and act on it.
  • Raise problems with data or timing as soon as they appear.

Example Abstract

This thesis examines whether time spent on image-based social media platforms is associated with social anxiety among first-year undergraduates. Using a cross-sectional survey of students at one UK university and a validated social anxiety scale, it tests the association while controlling for overall screen time. The findings are discussed in relation to social comparison theory, and the thesis concludes by identifying implications for student wellbeing services and directions for longitudinal research.

The abstract states the question, method, theory and contribution in under a hundred words. In your own abstract, add your main findings, which this illustrative version leaves out. Write it last, when you know what the thesis actually argues.

Common Mistakes and Checklist

  • A research question that is too broad.
  • A literature review written as a list of summaries.
  • A method that does not match the question.
  • Underestimating editing and formatting time.

Before You Submit

  • The question is stated clearly and answered in the conclusion.
  • The literature review leads to a clear gap.
  • Methods are justified and ethics approval is documented.
  • Results and interpretation are kept distinct.
  • Formatting and references follow the handbook.

How EssayDonkey Helps with Theses

Send your approved proposal, outline, handbook and the chapter you need. A writer at your level drafts a custom chapter, such as a literature review or methodology, written from scratch, plagiarism-checked and in your citation style.

Use it as a study reference for structure and argument. Your research, data and final thesis must be your own; we never invent data or results.

Frequently Asked Questions

What is the difference between a thesis and a dissertation?

Usage varies by country. In the UK, a dissertation is often the undergraduate or master's project and a thesis the doctoral one; in the US, it is often the reverse. The structure and standards are similar.

How long does a thesis take to write?

Plan in months, not weeks. Set chapter milestones backwards from the deadline and reserve a large block at the end for revision.

How long is a master's thesis?

It depends on the institution and field. Many fall between about 15,000 and 40,000 words. Check your handbook.

Which chapter should I write first?

Many students start with the literature review or methodology. Write the introduction and abstract last.

Can my research question change?

Yes, within limits. Discuss any change with your supervisor and update the introduction and literature review to match.

Can you help with one thesis chapter?

Yes. Send the outline, the approved proposal and the chapter brief for a custom chapter to use as a reference.

Should the thesis be written in the first person?

It depends on your discipline. Many social science and humanities theses accept "I" when describing your choices, while some science fields prefer an impersonal style. Follow your handbook.
