Every blog, newsletter and documentation site now promises "4 min read" or "12 min read" next to its headline, and those labels shape whether anyone clicks. But almost nobody asks what one minute of reading actually contains. The answer is a single, well-studied number — and once you know it, you can reverse-engineer every reading-time label you've ever seen, and budget your own writing with some precision.
The short answer: about 238 words
For an adult reading non-fiction silently, one minute holds about 238 words. That's the average silent reading rate for ordinary prose, and it's the same 238 wpm constant WordlyCount uses for its reading-time estimate. Fiction skews a little faster — roughly 260 wpm — because narrative sentences are shorter and carry less new information per word. So a practical planning band for "one minute of reading" is 200–300 words, with 238 as the center of gravity.
Where does 238 come from? Meta-analyses of reading-rate studies — the most frequently cited is Brysbaert's 2019 synthesis of more than 180 studies — converge on about 238 wpm for English non-fiction and about 260 wpm for fiction, and explicitly reject the marketing-friendly claim that adults read 500–700 wpm. That older folklore came from skimming tests, not comprehension tests, which is a distinction that matters below.
What fills a minute, by content type
The rate isn't a property of the reader alone; it's a property of the text. The same person moves across this table depending on what's in front of them:
| Content | Typical rate | Words in 1 minute |
|---|---|---|
| Easy fiction, light blogs | 260–300 wpm | 260–300 |
| Adult non-fiction (average) | 238 wpm | ~238 |
| Dense news, technical docs | 150–200 wpm | 150–200 |
| Textbooks, legal, academic | 100–150 wpm | 100–150 |
| Skimming for a fact | 400+ wpm | 400+ (with comprehension loss) |
Notice the asymmetry: easy text buys you maybe 20% more words per minute, but hard text costs you half. A 238-word paragraph feels like a snack in a listicle and like a workout in a philosophy paper. When you estimate reading time for your own writing, judge your difficulty honestly before you pick a rate.
How platforms derive their "min read" labels
There is no industry standard. Every platform picks a constant, divides, and rounds. Medium famously uses about 265 wpm; other publishers use 200, 225, or 250. The formula is always the same shape:
reading time = total words ÷ chosen rate, rounded up, with anything under the first threshold shown as "1 min read" rather than a humiliating "0 min read."
That's why the same article can be a 4-minute read on one site and a 5-minute read on another with identical text. It's also why you shouldn't treat the labels as measurements of your audience — they're estimates from a single constant, applied to everyone. If you want the number for your text at the research-backed rate, paste it into the WordlyCount counter and read the reading-time stat off the panel.
Skimming, careful reading, and the two speeds trap
People don't have one reading speed — they have at least two, and they switch without noticing. Skimming runs at 400+ wpm: eyes jump across headings, bold text and first sentences, picking up the shape of an argument. It's fast and useful, but comprehension and retention drop sharply — studies consistently find skimmers miss detail and remember less. Careful reading — technical material, contracts, anything you'll be tested on — runs nearer 100–200 wpm, with re-reading.
The practical takeaway for writers: on the web, assume most of your audience arrives skimming. Front-load the conclusion, use headings that carry meaning on their own, and put key numbers in bold — because at 400 wpm, that's what survives. The readers who slow down to 200 wpm are the ones already convinced.
Reading-time math you can do in your head
With 238 wpm as the constant, the arithmetic collapses into benchmarks worth memorizing:
- 1 minute ≈ 238 words — a solid paragraph or two.
- 2 minutes ≈ 476 words — a typical email or product update.
- 5 minutes ≈ 1,190 words — the classic magazine feature / long blog post. This is the same neighborhood as a 5-minute speech, though speech runs at roughly half reading speed.
- 10 minutes ≈ 2,380 words — a long-form essay or deep-dive guide.
- 20 minutes ≈ 4,760 words — roughly 15–20 printed pages; the ceiling for online attention without breaks.
Reversed, the same division answers the question every editor asks: "How long will this take to read?" Divide words by 238 and round up. It also works as a planning tool before you write: if the brief calls for a two-minute newsletter, your budget is about 475 words — stop there rather than at the bottom of the page. If you'd rather not do long division mid-edit, the counter keeps a live estimate on screen — but knowing where the number comes from is what lets you argue with it when your text is harder or easier than average.
