About the Reading & Presentation Time Calculator
People speak much more slowly than they read. A comfortable presentation pace is 120–150 words a minute, while silent reading runs at about 240. So a 1,300-word speech takes about 10 minutes to deliver but only 5–6 minutes to read.
Enter your word count (or pages). The calculator gives the speaking time, silent reading time and reading-aloud time, the time per slide, and — if you enter the minutes you have — how many words to write and how many slides to plan.
