When you have a hard limit, write to the slow column. Running short is recoverable; being cut off mid-point is not.

Writing for the ear

Spoken sentences need to be shorter than written ones, because a listener cannot re-read. A 40-word sentence that works on the page is very hard to follow aloud — and hard to deliver, because you run out of breath before the end.

The readability checker lists the sentences long enough to cause trouble aloud, with their word counts, so you can find them without reading the whole script again.

Frequently asked questions

What speaking speed should I use?
Plan with 150 words per minute. Slow, deliberate delivery is nearer 130 and quick delivery nearer 170, and all three are shown so you can see the range your script has to survive.
How many words is a 5 minute speech?
About 750 words at 150 words per minute. See how many words is a 5 minute speech for the detail.
Should I add time for pauses?
Yes, if the talk depends on them. Three deliberate five-second pauses cost 15 seconds — around 35 words of script. Question and answer time is separate and should never be counted inside your speaking time.
How do I find my own speaking rate?
Read 150 words of your script aloud at the pace you would actually use, and time it. If it takes 60 seconds you are at 150 words per minute; 70 seconds puts you at about 129. Set that figure with the slider and your estimates become genuinely accurate.
