演讲时间计算器

How speaking time is calculated

Speaking time is the word count divided by your pace: 110, 130 (the default) or 160 words per minute. Chinese characters are timed at 250 per minute at the average pace, scaled the same way, and added for mixed text. Examples at the average pace:

• 300 words → 2.3 min.
• 650 words → 5.0 min.
• 1,300 words → 10.0 min.

Writing to a time limit

Work the formula backward to get a word budget: multiply the minutes you have by 130. Then leave room for anything that is not your script.

• 1-minute pitch: about 130 words.
• 3-minute talk: about 390 words.
• 5-minute speech: about 650 words.
• 10-minute presentation: about 1,300 words, minus time for slides, demos or questions.

Adjusting for how you speak

Pick Slow (110), Average (130) or Fast (160) to match your delivery; Average is a fairly unhurried pace. Your own pace depends on nerves, the room, the language and how much you pause. To calibrate, time yourself reading one paragraph aloud and divide its word count by the minutes it took. For an exact personal rate, rescale the average figure: minutes at Average × 130 ÷ your rate. At 150 words per minute, for example, a 10.0-minute estimate becomes about 8.7 minutes.

Words to minutes at a glance

How long common word counts take to say aloud at each pace (slow / average / fast):

• 500 words: about 4.5 / 3.8 / 3.1 minutes.
• 1,000 words: about 9.1 / 7.7 / 6.3 minutes.
• 1,500 words: about 13.6 / 11.5 / 9.4 minutes.
• 2,000 words: about 18.2 / 15.4 / 12.5 minutes.

What the estimate does not include

Only words are timed. Rehearse with a clock before the real event, especially when the slot is strict.

• Pauses for emphasis, laughter, applause or audience questions.
• Time to change slides, run a demo or play a clip.
• Stage directions or speaker notes pasted with the script: remove them first, because every word counts.
• Numbers and dates: “2026” and “3.5” each count as one word but take longer to say.
