Reading Time / WPM Calculator
Enter a word count and your words-per-minute to estimate how long a piece of text takes to finish. Switch between silent reading, reading aloud, proofreading, audiobook narration and speed reading — or dial in a custom WPM.

AverageSits in the middle of the Brysbaert (2019) adult silent-reading distribution.
Default 238 WPM comes from Brysbaert (2019), a meta-analysis of adult silent reading of English fiction. Academic and technical texts typically run 30–50% slower.
Formula
reading time (minutes) = word count ÷ words per minute (WPM)
- · Defaults: silent reading 238 WPM, reading aloud 183 WPM, proofreading 200 WPM, audiobook narration 155 WPM, speed reading 400 WPM.
- · The 238 WPM mean (±65 SD) for silent reading comes from a Brysbaert (2019) meta-analysis of 190+ studies on English fiction.
- · Difficulty, vocabulary familiarity, age and language fluency all change speed; academic papers and technical docs typically run 30–50% slower than fiction.
- · Above ~450 WPM, comprehension generally drops sharply — most “speed reading” trades depth for pace (Rayner et al., 2016).
- · Chinese reading rates of roughly 150–250 characters per minute deliver comparable total comprehension thanks to higher information density per character.

Frequently asked
What WPM should I use?
Brysbaert (2019) puts adult silent reading of English fiction at 238 WPM with a ±65 SD, with most casual readers between 175 and 300. For technical docs, academic papers or second-language reading, dial down to 150–180 WPM. If you have a measured speed from a timed test, enter it directly for the best estimate.
Why do Medium and WordPress show different reading times than this tool?
Each platform picks its own default: Medium and Substack use 265 WPM and count each image as 12 seconds; WordPress uses 200 WPM; Hashnode and many news sites use 225 WPM. This tool defaults to 238 WPM (closer to the latest meta-analysis median) — adjust the WPM to match whichever platform you are mirroring.
Can I use this to measure my own WPM?
Yes. Pick a passage with a known word count (any editor shows word count), time yourself with a phone timer, then divide word count by minutes to get your WPM. The same words-per-minute formula works in reverse — feed your measured WPM back into the calculator to plan future reads with confidence.
Is 1000 WPM speed reading really possible?
Some courses claim it, but Rayner and colleagues (2016, Psychological Science in the Public Interest) reviewed the evidence and concluded that human visual and language processing peaks around 500–700 WPM. Anything substantially faster is usually skimming, and comprehension drops accordingly. Building vocabulary, improving previewing and reducing regression are more reliable wins than chasing extreme raw speed.
