Where the 238 wpm default comes from
Many calculators assume 200 or 250 words per minute without a source. We default to 238, from Marc Brysbaert’s 2019 paper “How many words do we read per minute? A review and meta-analysis of reading rate” in the Journal of Memory and Language, which pooled 190 studies of adult silent reading in English. Harder text is read more slowly, so for technical content pick a lower speed. Check difficulty with the readability checker.
Reading time FAQ
How is reading time calculated?
Word count divided by reading speed in words per minute. At the default 238 wpm, a 1,200-word article takes about 5 minutes.
What is the average reading speed?
Marc Brysbaert’s 2019 meta-analysis of 190 studies put average silent reading speed for adults at about 238 words per minute for non-fiction and 260 for fiction. Much higher figures quoted online usually come from speed-reading claims.
How many words is a 5-minute speech?
At a typical speaking pace of 130–150 words per minute, about 650–750 words.
Should I show reading time on my blog?
Many publishers do, because it sets expectations. Round to whole minutes and base it on a realistic speed like 238 wpm.
