Reading Time Calculator

Estimate a text’s silent reading time at 238 words per minute. Review word counts and the fixed-rate assumption before budgeting a reading session.

Use this result well

Inputs that matter
Text typed, pasted or uploaded into the editor, up to 500,000 UTF-16 code units.
Output to expect
A word count and rounded estimate of one silent reading pass, alongside the panel’s other text statistics.
How it works
Estimated minutes = counted words / 238. This fixed reference concerns average adult silent reading of English non-fiction.
  • Review the counted words. Segmentation can differ by language and browser, and this rate does not predict a child’s progress or reading in another language.
  • Study, document interpretation and editing require separate time. Use a measured personal pace when a tight schedule matters.
  • Copy and Print produce a statistics report. This panel does not track elapsed reading time or set a schedule.

Model and estimate references

The fixed 238 words/minute estimate uses the adult English non-fiction reference in Brysbaert’s 2019 reading-rate meta-analysis.

Reader, language, difficulty and purpose affect actual time. Study, interpretation, exercises and pauses need their own allowance. Native word segmentation is used where available; the CJK/whitespace fallback is approximate.

How it works

Count the supplied text

The estimate uses the panel’s word count for the text in the editor. Word boundaries use Intl.Segmenter when available and the documented fallback otherwise.

Apply the fixed rate

Divide the counted words by 238 to estimate minutes for one silent reading pass. The reference concerns adult English non-fiction and is not a personalized prediction.

Estimated minutes = word count / 238

Review rounded output

The panel shows rounded seconds, minutes or hours as appropriate. Use the word count and rate when you need the unrounded arithmetic, and measure the actual activity before relying on a tight schedule.

Example Scenarios

Count a simple ten-word passage and inspect its rounded estimate.

Text: One two three four five six seven eight nine ten.

→ 10 words; about 3 seconds at 238 words per minute.

Repeat the same ten-word sentence six times to check how duration scales.

Text: One two three four five six seven eight nine ten. One two three four five six seven eight nine ten. One two three four five six seven eight nine ten. One two three four five six seven eight nine ten. One two three four five six seven eight nine ten. One two three four five six seven eight nine ten.

→ 60 words; about 15 seconds at 238 words per minute.

Blank lines separate paragraphs without adding spoken or read words.

Text: One two three. Four five six.

→ 6 words and 2 paragraphs; about 2 seconds at 238 words per minute.

FAQ

Reading time is counted words divided by 238. Brysbaert’s 2019 review reports 238 words per minute as an average for adult silent reading of English non-fiction. It is a reference rate, not a measurement of an individual reader.

This panel uses fixed rates: 238 words per minute for reading and 150 for speaking. For a personal estimate, divide the displayed word count by your measured words per minute. Time a representative passage to check the assumption.

The fixed adult English reference does not predict a child’s progress, reading in another language, study mastery or time spent interpreting a complex document. Record the actual session when those distinctions matter.

The panel uses the browser’s Intl.Segmenter where available, with a whitespace/CJK-character fallback. Counts can differ by language and browser. Review the displayed word count, especially for mixed-language text, code or unusual punctuation.

Text analysis accepts up to 500,000 UTF-16 code units. The time is displayed as a rounded estimate alongside other text statistics. Copy and Print provide a statistics report; this panel does not run a stopwatch or track time spent reading.
