Thesis outline: a proven structure with page counts

A good outline is half the thesis: it determines the logic of the text, the size of each chapter, and whether your supervisor lets you write or sends the plan back. Here is how to build an outline that passes on the first try.

Why the outline is not skippable

The outline is not a formality for your supervisor, it is a tool for you: it exposes holes in the logic before you pay for them with weeks of rewriting. Reviewing an outline takes minutes; rewriting a finished chapter takes days. If nothing else, the outline breaks 40 pages into manageable blocks of 3 to 6 pages.

The standard structure with page estimates

For a bachelor thesis of around 40 pages, this split works:

  • Introduction: 2 to 3 pages (goal, research questions, thesis structure)
  • Theory chapter 1: 8 to 10 pages (definitions, theoretical background)
  • Theory chapter 2: 8 to 10 pages (the narrower context, prior findings)
  • Methodology: 3 to 5 pages (goal, hypotheses, sample, collection and analysis methods)
  • Results and discussion: 10 to 12 pages (results with tables and charts, interpretation)
  • Conclusion: 2 to 3 pages (answers to the questions, limitations, recommendations)

Theory and the empirical part should be roughly balanced. If theory runs 25 pages and the empirical part 8, the examiner will note it in the review.

A concrete worked example

Topic: The influence of social media on Gen Z purchase decisions.

  1. Introduction
  2. Consumer behaviour and purchase decision-making (concepts, decision-process models, factors)
  3. Social media in marketing (platforms, influencer marketing, Gen Z specifics)
  4. Research methodology (goal and hypotheses, questionnaire, sample n = 150, evaluation approach)
  5. Results and discussion (descriptive statistics, hypothesis testing, comparison with the literature)
  6. Conclusion

Note the logic: broad to narrow in the theory, and the empirical part mirrors exactly what the theory prepared. Chapter 2 supplies the concepts for the questionnaire, chapter 3 the context for interpretation.

The most common outline mistakes

  • Theory with no link to the empirical part: a chapter the research never uses does not belong in the thesis
  • Too many top-level chapters: 5 or 6 main chapters are enough, the rest are subsections
  • Half-page subsections: if a heading has less than a page of content, merge it
  • Missing discussion: tables alone, without interpretation and comparison with the literature, are not enough
  • No page estimates: without them the length cannot be controlled

An outline that matches your university

Faculties have their own guidelines: some require a separate Aims and Methodology chapter, others prescribe exact chapter names. Open your department template before finalizing. AIPráce generates an outline adapted to a specific university’s standards and distributes the page budget automatically; you edit the generated outline first, and the text is written only after you approve it.

FAQ

How many chapters should a bachelor thesis have?

Typically 5 or 6 main chapters including the introduction and conclusion: two theory chapters, methodology, and results with discussion. Finer structure belongs in subsections.

Does the supervisor have to approve the outline?

Formally not always, practically yes. An outline your supervisor signed off on protects you: it is hard to criticize a structure at the defence that the supervisor saw and approved.

How deep should the subsection numbering go?

Two levels (2.1, 2.2) are almost always enough; a third level (2.1.1) only in longer chapters. A fourth level in a bachelor thesis is almost always a mistake.
