Frequently Asked Questions

How many slides for a 10-minute presentation?

At normal pace (150 WPM), typically 8-12 slides. Use our reverse calculator for an exact number based on your content density and speaking style.

Does it count images and charts?

Yes. Each image adds ~10 seconds of viewing time and tables add ~15 seconds. These are factored into the total duration automatically.

Do I need to upload a file?

No — you can use the manual calculator with just a slide count. Upload is optional for more precise word-level analysis.
