Slides slow a talk down in ways a plain word count cannot capture, so a deck that looks short on paper can overrun in the room.
Presentation Time Calculator takes your speaker notes, a presenting pace and the number of slides, and estimates the total time and the time per slide, so you can pace a deck before you rehearse it.
How to use Presentation Time Calculator
- Paste your speaker notes into the editor.
- Set a presenting pace and enter how many slides you have.
- Read the total speaking time and the time per slide.
Use cases
- Pacing a conference talk against its slot.
- Balancing time across the slides in a deck.
- Rehearsing a pitch so it lands on time.
Good to know
Total time is your word count divided by the presenting pace, and time per slide divides that across the slide count, so both depend on the pace you set. Presenting is often slower than conversation, around 130 words per minute, and questions and transitions add time, so add a buffer.
Frequently asked questions
How is presentation time estimated?
It divides your word count by the presenting pace for total time, then spreads that across the number of slides for time per slide.
What presenting pace is realistic?
Presenting is often around 130 words per minute, a little slower than conversation, but set the pace that matches your style.
Should I add time for questions?
Yes. Transitions, pauses and questions are not in the estimate, so add a buffer when planning the slot.
