Speech Time Calculator — Free Online Tool
Got 1,500 words and 10 minutes on stage? This speech time calculator converts any word count into speaking time at your pace — so you never run long (or finish embarrassingly early).
What is the Speech Time Calculator?
Most people speak at 130–150 words per minute conversationally; formal presentations run slower, around 100–130 wpm, because of pauses and emphasis. That means a '10-minute talk' is roughly 1,000–1,300 words — far fewer than writers expect when drafting.
Pros build in a buffer: aim to fill about 90% of your slot, since nerves speed some speakers up while audience reactions slow others down. Rehearse out loud with a timer — silent reading is always faster than actual speaking, and no speech time calculator can account for your dramatic pauses.
How to use this calculator
- Enter your script's word count.
- Set your speaking rate (130 wpm is a good default).
