How reading time is estimated
The calculation is simple division: your word count divided by a reading speed. This tool uses 225 words per minute for silent reading, a widely used average for adults reading ordinary prose, and 130 words per minute for reading aloud, which matches a comfortable presentation pace with natural pauses. Everything is counted in your browser as you type; your text is never uploaded or stored.
Real readers vary, of course. Dense technical writing or legal text can slow people to 150 words per minute or less, while someone skimming a familiar topic might double the average. Reading on a phone tends to be slightly slower than on paper, and anything with tables, code or footnotes takes longer than the raw word count suggests. Treat the figures as a solid estimate for planning, not a stopwatch.
Words are counted the same way word processors count them: any run of characters separated by spaces or line breaks is one word. That means the total should match what you see in Word or Google Docs, so you can check a document there and trust the timing here.
Worked examples
Writing a speech? Work backwards
Speaking pace is the number that catches people out. Most speakers who sound unhurried deliver around 130 words per minute once pauses, emphasis and the odd laugh are included, which is far slower than reading in your head. If you draft a best man speech that takes 4 minutes to read silently, it will take closer to 7 to deliver. Use the speaking figure, not the silent one, and rehearse with a timer at least once.
- 2-minute toast: about 260 words.
- 5-minute speech: about 650 words.
- 10-minute talk: about 1,300 words.
- 15-minute presentation: about 1,950 words.
- 20-minute conference slot: about 2,600 words.
- 45-minute lecture: about 5,850 words.
If your draft runs long, cut whole points rather than squeezing the pace. Audiences follow a speaker at 130 words per minute; they lose one at 170.
Why reading time matters online
Readers decide whether to commit to an article within seconds, and a time estimate helps them do it. Publishing platforms popularised the "4 min read" label because it measurably improves engagement: people are more willing to start something when they know the cost. If you write newsletters, blog posts or reports, checking the reading time before you publish tells you whether you are asking for 3 minutes of someone's day or 15.
It also keeps documents honest. A briefing note that claims to be a two-minute read but weighs in at 1,200 words is a five-minute read, and the people receiving it will notice. The same discipline helps with emails: anything that takes more than a minute to read is competing with everything else in a busy inbox. Paste your draft in above, check the numbers and trim until the promise matches the text.
Frequently asked questions
How is reading time worked out?
The tool divides your word count by 225 words per minute, a typical adult silent-reading pace, and rounds to the nearest second. Speaking time uses 130 words per minute, which suits speeches and presentations delivered at a comfortable pace.
How long should a 5-minute speech be?
About 650 words. At a speaking pace of 130 words per minute, 5 minutes of talking is 5 times 130, which is 650 words. A 10-minute talk is roughly 1,300 words and a 20-minute talk roughly 2,600.
Why do other sites give a different reading time?
They assume a different reading speed. Estimates across the web range from about 200 to 300 words per minute, so the same article can be labelled 4 minutes on one site and 6 on another. This tool uses 225 words per minute, a widely used middle figure for adult silent reading.
Is 225 words per minute right for every kind of text?
No, it is an average for ordinary prose. Dense or technical material can drop readers to 150 words per minute or less, while skimming familiar content can be much faster. Treat the result as a good estimate rather than a stopwatch.
Is my text stored or uploaded anywhere?
No. The counting and timing happen entirely in your browser using JavaScript. Nothing you type or paste leaves your device, and refreshing the page clears it.
