Words to minutes formula
Speaking minutes equal script words divided by words per minute. Add planned pauses, slide transitions, and a buffer when the talk must fit a strict time limit.
How to choose words per minute
Use slower values for live presentations, emotional speeches, rooms with echo, or audiences that need time to process. Use faster values only when the material is familiar and rehearsed.
Why a rehearsal can differ from the calculator
Live delivery includes breaths, emphasis, laughter, demos, missed lines, slide friction, and room timing. The estimate is a planning tool, not a stopwatch result.
How to shorten a script
Cut repeated setup, long qualifiers, and examples that do not change the point. Then rerun the timing and keep a buffer for the actual delivery.
