Reading speed
225 words per minute is this calculator's default estimate. Real reading speed varies by reader, material and purpose, and changing this value changes the estimate.
Type any speed between 50 and 1,200, or pick a preset above.
A separate setting for reading aloud, defaulting to 150 WPM. It never changes the reading estimate.
Clear Text empties the text box and keeps your speeds. Reset Speeds restores 225 and 150 WPM and keeps your text.

How Reading Time Is Calculated
reading time = word count ÷ words per minute
This calculator uses a default estimate of 225 words per minute, so 450 words comes out at 450 ÷ 225 = 2 minutes.
Change the speed and only the estimate changes; the word count stays the same. The same 450 words are about 2 min 30 sec at 180 WPM, 2 min at 225 WPM, and 1 min 30 sec at 300 WPM.
The result is shown in minutes and seconds, with seconds carried into minutes, so a text just under a minute reads as “59 sec” rather than a rounded-up minute.
Speaking time uses the same formula with a separate, lower words-per-minute setting, because reading aloud is slower than reading silently.
Why Reading Speed Varies
No single words-per-minute figure fits every reader. Speed depends on the person, the difficulty of the material, and what they are trying to get out of it.
Careful reading
Slower. Dense, technical or unfamiliar material, or anything being studied rather than browsed.
General reading
The default range. Familiar prose read straight through.
Skimming and scanning
Much faster than any of these estimates, because most of the words are never read.
Reading aloud
Slower again, which is why speaking time has its own setting.
Treat the output as a planning estimate, not a measurement of any individual reader.

How Words Are Counted
A word is a run of letters or digits in any script, so accented Latin text such as “café naïve résumé” counts as three words and Cyrillic text counts normally.
Contractions (“don’t”) and hyphenated compounds (“state-of-the-art”) each count as one word. Decimal and grouped numbers such as 3.5 and 1,000 stay intact, and a URL or email address counts as one word rather than splintering into its parts.
Chinese and Japanese are written without spaces between words, so there is no reliable way to segment them here. Rather than reporting no words at all, those characters are counted and converted to an estimated word count at two characters per word, and the result is labelled as an estimate.
The readability figure is an approximate English-language reading-ease heuristic based on sentence length and estimated syllables. It needs at least 30 words across two or more sentences, and it is not a scientific measure of comprehension.
Frequently Asked Questions
Reading time is the word count divided by a reading speed in words per minute. This calculator defaults to 225 words per minute, so 450 words comes out at about 2 minutes.
225 words per minute is a reasonable default for general prose. Lower it for dense, technical or unfamiliar material and raise it for light or familiar content. The speed is editable, so you can match your own audience.
No. It is an estimate from word count alone. Actual reading time depends on the reader, the difficulty of the text, formatting, attention, and whether someone is reading closely or scanning.
Speaking time uses its own words-per-minute setting, defaulting to 150, because people speak aloud more slowly than they read silently. Changing one speed never changes the other.
Words are detected as runs of letters or digits in any script, so accented Latin and Cyrillic text count normally. Contractions and hyphenated compounds count as one word, decimal and grouped numbers stay intact, and a URL or email address counts as a single word instead of several.
Partly, and it says so. Chinese and Japanese are not written with spaces between words, so the calculator counts the characters and converts them to an estimated word count at two characters per word rather than claiming an exact segmentation.
The reading-ease estimate needs at least 30 words of Latin-script prose across two or more sentences. Below that there is not enough text for the score to mean anything, so no score is shown rather than a fabricated one.
No. The text is processed locally in your browser and is not sent to a server.
