⏱️ Speech Duration & Reading Time by WPM Pace Calculator
Estimate spoken presentation duration and silent reading time based on word count and words per minute (WPM) speaking delivery pace (110–350 WPM).
Brysbaert 2019: the average across 190 studies of adult English readers.
What Speech Duration & Reading Time by WPM Pace Calculator Does
Reading time is word count divided by a reading rate. The arithmetic is trivial; the rate is where almost every calculator goes wrong, because most of them use a round 200 or 250 words per minute that traces back to nothing in particular.
There is a better number. Brysbaert's 2019 meta-analysis pooled 190 studies covering 18,573 participants and put average adult silent reading of English non-fiction at 238 words per minute, fiction at 260, and reading aloud at 183. Those are the defaults here, and they are the figures a "5 min read" badge should be built on.
Speaking is much slower than reading, and that is the distinction that matters most in practice. A script that takes four minutes to read silently takes over five to read aloud, and longer still delivered to an audience with pauses. Anyone timing a conference talk from a silent-reading estimate will overrun.
The honest caveat is that individual variation swamps the average. Reading speed differs enough between people that a single number is close to meaningless for any one reader, which is why this shows a range as well as a figure.
How to Use Speech Duration & Reading Time by WPM Pace Calculator

Formula Used by Speech Duration & Reading Time by WPM Pace Calculator
Reading time
minutes = words ÷ words-per-minute
- 238 wpm
- adult silent reading, English non-fiction — Brysbaert 2019
- 260 wpm
- the same for fiction, which reads faster
- 183 wpm
- reading aloud, limited by articulation rather than comprehension
Worked example
A 1,500-word article.
- Silent non-fiction: 1500 ÷ 238 = 6.3 minutes
- Read aloud: 1500 ÷ 183 = 8.2 minutes
- Presented with pauses at 140 wpm: 1500 ÷ 140 = 10.7 minutes
Result: Six minutes to read, but nearly eleven to deliver — the gap that catches people out when timing a talk.
How long a piece takes
Silent non-fiction reading at 238 wpm, and reading aloud at 183 wpm.
| Length | Silent | Aloud |
|---|---|---|
| 300 words (a short post) | 1 min 16 sec | 1 min 38 sec |
| 800 words (a news article) | 3 min 22 sec | 4 min 22 sec |
| 1,500 words (a long-form post) | 6 min 18 sec | 8 min 12 sec |
| 3,000 words (a feature) | 12 min 36 sec | 16 min 24 sec |
| 10,000 words (a long report) | 42 min 1 sec | 54 min 39 sec |
| 80,000 words (a novel) | 5 hr 36 min | 7 hr 17 min |
Rates and where they come from
| Activity | Words per minute | Source |
|---|---|---|
| Silent, fiction | 260 | Brysbaert 2019 meta-analysis |
| Silent, non-fiction | 238 | Brysbaert 2019 meta-analysis |
| Reading aloud | 183 | Brysbaert 2019 meta-analysis |
| Presenting to an audience | ~140 | Convention, not a measured average — deliberately slower to allow pauses |
| Skimming | 400+ | Not reading; comprehension falls sharply above roughly 300 wpm |
How to Read Your Result
Speed reading claims do not survive testing
Rates in the thousands of words per minute come from skimming, and the research is consistent that comprehension falls as speed rises past a few hundred. There is a real trade-off between coverage and understanding, and no technique removes it.
The estimate ignores everything difficult
Equations, tables, code, diagrams and unfamiliar terminology all slow a reader down, as does going back to reread — which people do constantly. For technical writing, treat the figure as a floor.
For a talk, rehearse rather than calculate
Delivery rate varies enormously with nerves, audience and material. A calculated figure is a starting point for deciding whether a script is roughly the right length; only reading it out with a stopwatch tells you whether it fits.
Limitations & Accuracy Notes
- The cited rates are for adult readers of English. Other languages, and children or learners, differ substantially.
- Individual variation is large enough that any single figure is a poor prediction for a specific person.
- Rereading, skipping and skimming are all ignored, and all are normal reading behavior.
- Word counting splits on whitespace, so hyphenated compounds, numbers and code count as single words.
- Nothing here accounts for images, tables, equations or code, which change how long a page takes far more than the word count does.
