How many slides should a defense deck usually have?

It depends on the school and presentation time, but 10 to 20 slides is a common range. More important is whether each slide carries one clear point.

Should speaking notes be prepared together with the slides?

Yes. Slides only highlight the key points, while notes handle transitions, explanation, and emphasis, so they work best when prepared together.

Can I start the deck before the thesis is fully final?

You can sketch the structure early, but the final version is better built after the thesis structure and core findings are relatively stable.

How to Prepare a Thesis Defense PPT | Turn a Draft into Slides and Speaking Notes

This guide helps you extract the background, methods, results, and conclusion logic from your thesis and turn it into a sharper slide deck with speaking notes.

What this page helps you do first

Extract a presentation storyline instead of shrinking the paper onto slides
Prepare speaking notes, charts, and page rhythm together
Best used in the last one to two weeks before the defense

The biggest defense slide problem is rarely visual style

Most weak defense decks fail because the paper contains far more detail than the presentation can carry, so authors do not know what to cut and what to keep.

A stronger deck compresses the thesis around four lines: research problem, method, key result, and conclusion.

A common presentation order that works

Background and research problem
Methods, samples, or technical route
Key results and supporting charts
Conclusion, contribution, limits, and next steps

Do not optimize for slide count alone

Let each slide answer one question only
Keep charts and comparisons that directly support the conclusion
Rehearse the speaking notes with the page flow instead of polishing visuals only

Best workflow to connect next

If the thesis draft is already stable, move directly into the defense page. If the structure is still moving, return to the outline or sample pages first.
