How the math works
minutes = words 梅 wpm
words = minutes 脳 wpm
130 words per minute is a common average for spoken English. Read-aloud is often slower; auctioneers and debate rebuttals are faster. Time your first paragraph if you need a personal number.
FAQ
Does this count the way Word does?
It splits on whitespace. Hyphenated words count as one. It does not match every word processor, but it is close enough for timing a talk.
Should I write a 10-minute speech at 1,300 words?
At 130 wpm, yes. Leave a little slack for pauses, laughs, and slides. Many speakers write 10鈥?5% fewer words than the math suggests.
