Frequently asked questions
How is the time per slide calculated?
It divides your actual presentation time (total time minus break time) by the number of slides.
How do I account for Q&A time?
Enter your expected Q&A time in the break time field — the calculator subtracts it before dividing the remaining time across your slides.
How many slides should I use for a 20-minute talk?
At roughly 1-2 minutes per slide, that's about 10-20 slides. Enter 20 minutes and try different slide counts to see what fits.
How can I use this calculator during rehearsal?
Use the calculated time-per-slide as your target and check a timer against it on each slide during rehearsal to avoid running over.
Can I use this for a strict conference time slot?
Yes — enter your allotted total time and slide count to instantly see how much time you can spend per slide without going over.
