Presentation time calculator
Estimate your delivery time and the word budget left after pauses, demonstrations and questions.
How it works
A worked example
A five-minute slot with one minute reserved for pauses or Q&A leaves a 520-word budget at 130 words per minute.
Assumptions to check
Speaking pace is adjustable. A timed rehearsal is a better guide than a generic pace. Pasted text is counted on this device and never uploaded.

Does slide count determine speaking time?
No. A demonstration or complex chart can take longer than several simple slides. Estimate non-speaking time and rehearse.
How does the word count work?
Groups of Unicode letters or numbers count as words. Apostrophes within words stay together. Hyphenated words may be counted as separate words.
Planning estimates, not official academic results. Your course and institution set the rules.
From this result to your next step.
Budget for more than speaking
Include pauses, transitions and other non-speaking time. The word count is a pacing estimate; slides, audience questions and demonstrations can change the actual duration. Enter the speaking rate that matches your own rehearsal.
Use a timed rehearsal to refine the estimate
Read the script aloud with normal pauses, then compare it with the calculated estimate. If the talk runs long, remove or simplify material before increasing the assumed pace. A saved script is part of the plan backup, so avoid including private information unnecessarily.
