Reading Time Estimator
Word count + reading speed → minutes / hours. Speed presets calibrated to research averages.

- At slow (130 wpm)19.2 min
- At average (250 wpm)10.0 min
- At fast (400 wpm)6.3 min
Step-by-step
- Reading time (min) = words / wpm = 2,500 / 250 = 10.0000 min.
- Equivalent: 0.1667 hours = 600 seconds.
How to use this calculator
- Enter word count — copy-paste your draft into a Google Doc and use Tools → Word Count, or paste into wordcounter.net.
- Pick a speed preset honestly — most adults are "average" (250 wpm) on typical prose.
- For dense technical or academic content, use "slow" (130 wpm) — this is the realistic comprehension-paced speed for unfamiliar material.
About this calculator
Reading speed for adults averages 200-300 words per minute (wpm) for prose. Research summary: technical or dense academic text typically reads at 100-150 wpm because of comprehension friction; light prose (popular fiction, blog posts) at 300-350 wpm; trained speed-readers can sustain 400-600 wpm with measurable comprehension loss past ~500 wpm. The 250 wpm "average" used here is the Carver (1990) calibration — the most-cited value in reading-speed literature. Medium uses 265 wpm; Pocket uses 220 wpm; the BBC iPlayer uses 200 wpm — all close. For audiobooks, 150-160 wpm is the typical narration speed (which is why audiobook duration is roughly 2× silent-reading time at default playback). This calculator gives a quick estimate plus a comparison band — useful when planning content lengths or audiobook commute fit.
