Reading Time Calculator — how long to read a text

How it works

Estimating how long a text takes to read is simple division:

Reading time (minutes) = word count ÷ reading speed (words per minute)

The only judgement call is the reading speed. A large meta-analysis by Brysbaert (2019), pooling 190 studies and over 18,000 readers, found that average adult silent reading is about 238 words per minute for non-fiction and 260 wpm for fiction (fiction uses shorter, more common words). Reading aloud is slower — about 183 wpm — because speech has to keep up with the voice. These are averages: most adults reading non-fiction silently fall between roughly 175 and 300 wpm, and the figures are lower for children, older adults and second-language readers.

Notably, these research-backed numbers are lower than the 300–400 wpm often quoted on blogs and in speed-reading marketing. Genuine reading — with comprehension — is bounded by how fast the eyes can fixate and move, so claims of many hundreds or thousands of words per minute describe skimming, not reading. Pick the rate that matches your task: the default 238 wpm for typical silent reading, or switch to the aloud rate when timing a speech or narration.

Worked example

A 1,000-word article at the default 238 wpm silent-reading rate:

1,000 ÷ 238 ≈ 4.2 minutes

Read the same article aloud at 183 wpm and it takes 1,000 ÷ 183 ≈ 5.5 minutes — useful when estimating how long a script will run.

Frequently asked questions

How is reading time calculated?

Divide the number of words by the reading speed in words per minute. For 1,000 words at 238 wpm, that is 1,000 ÷ 238 ≈ 4.2 minutes.

What is the average reading speed?

Brysbaert's 2019 meta-analysis puts average adult silent reading at 238 words per minute for non-fiction and 260 for fiction, with reading aloud around 183 wpm. Most non-fiction readers fall between about 175 and 300 wpm.

Why is the default lower than speed-reading claims?

Because comprehension limits reading to a few hundred words a minute — the eyes can only fixate and move so fast. Rates of 500+ wpm reflect skimming with reduced understanding, not full reading, which is why the research-based average is used here.

Should I use the silent or aloud rate?

Use the silent rate (238 wpm) to estimate how long an article or chapter takes to read to yourself. Use the aloud rate (183 wpm) when timing a speech, presentation or narration that will be spoken.

Does reading speed vary by person and text?

Yes. It depends on the reader's age, fluency and familiarity with the topic, and on the text's difficulty and word length. Treat the result as a solid average estimate, and adjust the words-per- minute figure if you know your own pace.

How many words are on a typical page?

It varies with formatting, but a paperback page holds roughly 250–300 words and a double-spaced manuscript page about 250. To estimate a book's reading time, multiply pages by words per page to get a word count, then divide by your reading speed.
