How Many Slides for a 20-Minute Presentation?
A 20-minute presentation needs about 20 slides, at roughly one slide per minute. A fast, visual talk can use up to 40, and a talk that spends longer on each slide can use as few as 10.
Slide count by pace
| Pace | Time per slide | Total slides |
|---|---|---|
| Fast | 30 seconds | 40 slides |
| Standard | 1 minute | 20 slides |
| Relaxed | 2 minutes | 10 slides |
How to plan a talk this long
Twenty minutes is common for conference sessions and sales presentations.
Guy Kawasaki’s well-known 10/20/30 rule suggests just 10 slides for 20 minutes, which works when you speak to each slide at length.
Choose your pace by content. Pitches can run on 10 slides, while a walkthrough with screenshots may need 20 or more.

Frequently asked questions
How many words is a 20-minute presentation?
At an average speaking pace of about 130 words per minute, 20 minutes of speaking is about 2600 words. Everyone’s pace differs, so time yourself reading it aloud.
Do the title and closing slides count?
The counts above include them, so 20 slides leaves about 18 content slides. You spend little time on these two slides, so they barely change the total length.
Are fewer slides always better?
Not necessarily. How much you say sets the length, not the slide count. With one idea per slide, a deck with more slides can move faster and be easier to follow.
