How this calculation works
The word count is divided by 238 words per minute, the measured average for adult silent reading of prose, to estimate the time.
What the results mean
- 238 wpm
- The average silent reading rate for adults. Skimming is faster; dense or technical text is slower.
- Words counted
- The figure the estimate is built from — runs of non-space characters. If this looks wrong, the time will be wrong in proportion.
- Speaking time
- A separate estimate at around 130 words per minute, the rate of comfortable presentation delivery. It runs roughly twice the silent reading time, which is the number people want for a talk or a script.
Common problems and fixes
- The estimate feels far too fast for my readers
- The 238 wpm figure is for adult silent reading of ordinary prose. Technical documentation, legal text, anything with code samples or equations, and material in a reader's second language all run substantially slower — often half the rate. Treat the number as a floor for that kind of writing rather than an expectation.
- I need the time for reading aloud, not silently
- Use the speaking estimate rather than the reading one. Silent reading is roughly twice as fast as comfortable speech, so publishing a silent-reading figure on something intended to be presented understates it badly — a ten-minute talk reads as a five-minute article.
- My article has images and code blocks the count ignores
- It does, and so does every word-based estimate. Readers spend real time on a diagram or a code sample that contributes almost nothing to the word count. A common adjustment is to add roughly ten seconds per image and to treat code blocks as slower than prose, then round up.
Frequently asked questions
How accurate is the estimate?
It is a yardstick, not a promise. 238 wpm is a solid average, but individual pace varies widely and technical or unfamiliar material reads more slowly. Use it for relative comparison rather than an exact timer.
Where does the 238 words per minute figure come from?
It is the mean rate from a large meta-analysis of silent reading studies for adults reading non-fiction prose in English. It is a better basis than the 200 or 250 that circulate as round numbers, though the underlying spread is wide — the same research puts the normal range at roughly 175 to 300 words per minute.
Should I publish a reading time on my articles?
It reliably helps readers decide whether to start now or save for later, which is why most publishing platforms show one. Round to whole minutes, keep it honest for long pieces rather than flattering, and remember it is a courtesy rather than a ranking signal — no search engine rewards the label itself.
