Presentation Length Guide
Word count targets for presentations at normal speaking pace (120–130 WPM). Presentations are spoken slower than casual speech to allow the audience to follow your slides.
| Presentation Length | Slow (120 WPM) | Normal (130 WPM) | Slides (@ 90 sec/slide) |
|---|---|---|---|
| 5 minutes | 600 words | 650 words | ~3–4 slides |
| 10 minutes | 1,200 words | 1,300 words | ~6–8 slides |
| 15 minutes | 1,800 words | 1,950 words | ~9–12 slides |
| 20 minutes | 2,400 words | 2,600 words | ~12–15 slides |
| 30 minutes | 3,600 words | 3,900 words | ~18–22 slides |
| 45 minutes | 5,400 words | 5,850 words | ~27–33 slides |
| 60 minutes | 7,200 words | 7,800 words | ~36–45 slides |
How Many Slides for Each Presentation Length?
| Presentation Length | Min slides (2 min/slide) | Ideal (90 sec/slide) | Max slides (60 sec/slide) |

| 10 minutes | 5 slides | 6–8 slides | 10 slides |
| 15 minutes | 7–8 slides | 9–12 slides | 15 slides |
| 20 minutes | 10 slides | 12–15 slides | 20 slides |
| 30 minutes | 15 slides | 18–22 slides | 30 slides |

Presentation Timer Tips
Practice with the countdown every time
Never present without timing yourself in practice. Set the countdown to your allotted time, press start when you begin, and practice until you can finish your content with 1–2 minutes to spare — not exactly on time. Cushion prevents rushing.
Use the slide calculator to plan first
Before building your slides, use the Slide Calculator tab above. Enter your total time and planned slide count to see seconds per slide. If it shows under 45 seconds per slide, you have too many slides. Over 3 minutes per slide means too few.
What to do when you are running over time
If you notice you are running behind during a live presentation: skip your least important slide entirely (not rush through it), cut your second example and deliver only the strongest one, and move your conclusion forward. Never rush your ending — a clean close is more important than covering every point.
Presentation Timing by Context
Investor pitch (5–10 minutes)
The Sequoia Capital pitch format and most accelerator demo days allow 5–8 minutes per company. At 130 WPM that is 650–1,040 words. Most successful pitches use 10–12 slides covering: problem, solution, market size, traction, team, and ask.
Conference and keynote talks (18–45 minutes)
Conference presentations typically run 18–30 minutes with 10–15 minutes for Q&A. TED's 18-minute format has become the de facto standard for keynote-style talks worldwide. At 130 WPM, 18 minutes = approximately 2,340 words.
Classroom and academic presentations (5–20 minutes)
Classroom presentations are usually timed strictly by the instructor. Going over time is penalised in most graded settings. Use the countdown timer above during every practice session to build an internal sense of pace before the real presentation.
Sales and business presentations (20–45 minutes)
Business sales presentations typically run 20–30 minutes with significant time for questions and discussion. Leave 30–40% of your total slot for Q&A — a presentation that generates questions is a presentation that is working.
