Reading Time Calculator

Background.

Every reading-time estimate is a single division, words over words per minute, and all of the uncertainty sits in the second number. A 1,500-word article is 1,500 words for everyone. For a fluent adult reading silently it is a little over six minutes; read out loud it is more than eight; for someone reading in a second language, or studying to remember, it is longer again.

The defaults here come from the largest review of the question. Marc Brysbaert's 2019 meta-analysis pooled 190 studies and 18,573 participants and put silent reading of English non-fiction at 238 words per minute, fiction at 260, and reading a prepared text aloud at 183. Those figures are lower than the speeds often quoted in popular writing, and they are averages: your reader may be well above or below them, which is why every rate is an editable field.

The calculator also runs backwards, which is the direction speechwriters and editors usually need. Give it a slot of 18 minutes and it returns the 4,284 words that fill it at 238 words per minute. Remember the slot is measured at the silent rate, so a script meant to be spoken should be sized with a speaking rate in that field, or it will overrun.

Lengths can be entered as words, pages or characters. Pages are converted with a words-per-page setting that defaults to 250, the figure for a double-spaced 12-point manuscript page; a typeset paperback holds more, roughly 350 to 450. Characters are divided by five, the text-entry convention that counts a word as five characters including the space after it. If you have the text itself rather than a count, the word counter will count it for you.

What is reading time calculator?

Reading time is the length of a passage divided by a reading rate. The length can be counted exactly; the rate is a property of the reader and the task, not of the text. Researchers separate several rates that everyday estimates blur together: silent reading for comprehension, reading aloud, which is capped by how fast a voice can articulate, and the much faster skimming and scanning that Ronald Carver's model treats as different gears altogether. Brysbaert traces the gap between fiction and non-fiction to word length, since non-fiction uses longer words. A reading-time figure is therefore only meaningful alongside the rate that produced it.

How to use this calculator.

1. 01Pick a direction: 'Length → reading time' for a passage you can measure, or 'Time slot → length' to find how many words fit the minutes you have.
2. 02For a length, choose words, pages or characters and enter the figure. For pages, first set words per page to match the format; for characters, use a count that includes spaces.
3. 03For a time slot, enter the minutes. If the text will be spoken, replace the silent reading rate with your delivery rate so the word count fits the talk rather than a silent read.
4. 04Adjust the rates to the reader: 260 for fiction, lower for dense technical material, reading to memorise, or a second-language reader. Timing yourself over a few pages of the real text gives the best figure.
5. 05Read the labelled time for a quick answer and the decimal minutes when you need to add several passages together; add the decimals and convert the total once.

The formula.

Everything starts from a word count W. Words are taken as entered; pages become W = pages × words per page; characters become W = characters ÷ 5. Silent reading time is t_silent = W ÷ R_silent and read-aloud time is t_aloud = W ÷ R_aloud, both in minutes. In the reverse direction the word count is W = t_slot × R_silent, so a slot and its word count convert back and forth without drift. The other outputs restate W: pages = W ÷ words per page and characters = W × 5. The time labels are built by converting the minutes to seconds, rounding to the nearest whole second and then splitting into hours, minutes and seconds. Because both times divide the same word count, their ratio is fixed by the rates alone: at the defaults the read-aloud time is always 238 ÷ 183 = 1.3005 times the silent time, whatever the length.

The source of this page's rate defaults: across 190 studies and 18,573 participants, silent reading of non-fiction averages 238 wpm, fiction 260 wpm, and reading aloud 183 wpm. Access note: the DOI resolves to Elsevier and ScienceDirect returned HTTP 403 to automated retrieval on 2026-07-29, so the figures were taken from the open abstract and cross-checked against the same figures already cited on this site's word counter; the full text was not opened.

Their speech-rate guidelines put 'average' spontaneous and broadcast speech at 125–160 wpm, which does not conflict with Brysbaert's 183 wpm for oral reading — the two measure different constructs, and prepared reading being faster than unscripted speech is the expected direction.

The definition behind the characters unit: a "word" in text-entry research is five characters including the following space. This is a definition rather than a measurement, and it is the same divisor the live typing speed calculator on this site uses, so the two pages agree on what a word is.

It supplies the page geometry from which the 250-words-per-page convention is derived, and deliberately not a words-per-page number — no standards body publishes one, which is why words-per-page is an editable input on this page and is labelled a convention rather than a standard.
