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.
Word count, not page count
In English-speaking universities the length of a dissertation is set in words, and the number is not a rule of thumb but a limit in your department handbook. Trinity College Dublin gives history undergraduates 8,000 to 10,000 words and says outright that the limit is exactly that, with no ten percent tolerance. At the University of Edinburgh an MSc research dissertation runs to around 10,000 words with an absolute maximum of 12,000, after which the marker stops reading. The page count follows from the word count and from your line spacing, never the other way round.
| Type of thesis | Word limit, Trinity and Edinburgh handbooks | Roughly, at 1.5 line spacing |
|---|---|---|
| Bachelor dissertation | 8,000 to 10,000 words | about 25 to 30 pages |
| Master dissertation | 10,000 to 12,000 words | about 30 to 40 pages |
Count it in Word rather than by eye: click the word count in the status bar and read the figure from the window that opens. Then check what your own handbook leaves out, because that is where two departments diverge: Trinity excludes footnotes, appendices and the bibliography, while Edinburgh counts everything except figure legends, tables, appendices and references. A page of A4 at 12 point and 1.5 spacing holds roughly 2,000 characters, which is why the page count is an estimate and the word count is not.
Treat the table as a default and your handbook as binding, because the limit is enforced mechanically and a master dissertation is often barely longer than a bachelor one in words. If your handbook gives a page count instead, ask which font size and line spacing it assumes, otherwise the instruction cannot be checked at all.
A concrete worked example
Topic: The influence of social media on Gen Z purchase decisions.
- Introduction
- Consumer behaviour and purchase decision-making (concepts, decision-process models, factors)
- Social media in marketing (platforms, influencer marketing, Gen Z specifics)
- Research methodology (goal and hypotheses, questionnaire, sample n = 150, evaluation approach)
- Results and discussion (descriptive statistics, hypothesis testing, comparison with the literature)
- 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.
