Work out speaking time from word count instantly with clear inputs, formula shown and shareable results.
At a measured 130 words a minute, an 1800 word script takes 13.85 minutes of pure delivery, or 15.92 minutes with a 15% allowance for pauses and interaction. The practical rule is about 1300 words for a ten minute slot - which is why conference talks are usually far shorter than speakers first draft.
Base speaking time
minutes = words / words per minute
With allowance
total = base x (1 + pause allowance)
About 1200-1400 at a measured pace, less if you take questions or pause for slides.
Because rehearsal is faster than live delivery, and unplanned interaction, technical hitches and audience questions are rarely budgeted.
