A 10-minute read is approximately 2,380 words — based on the research-backed average adult reading speed of 238 words per minute. If you're writing a speech or podcast script, that same 10 minutes covers only 1,300 words at a natural speaking pace.
The difference matters. A blog post and a presentation are both "10 minutes" — but they need completely different word counts. Here's everything you need to know.
The quick answer: words by context
| Context | Speed | 10-minute word count |
|---|---|---|
| Silent reading (average adult) | 238 wpm | ~2,380 words |
| Silent reading (slow or technical content) | 150–180 wpm | ~1,500–1,800 words |
| Silent reading (fast reader) | 300 wpm | ~3,000 words |
| Speaking / presenting / reading aloud | 130 wpm | ~1,300 words |
Most online "reading time" calculators use between 200–265 wpm for silent reading. The 238 wpm figure comes from a 2019 meta-analysis of over 100 studies and 18,000 participants — it's the most rigorously sourced number available, and the one wordscounter.io uses.
Why the number varies
Reading speed isn't fixed. Several factors push it up or down:
Text complexity. A casual blog post reads at 200–250 wpm. Dense technical documentation drops to 100–150 wpm. Academic papers and legal text can slow fluent readers to 80–120 wpm. A "10-minute read" on a developer documentation page is closer to 1,000–1,500 words, not 2,380.
Reader age and experience. Adults average 238 wpm. Teenagers land at 195–204 wpm. Children in grades 1–6 read at 80–185 wpm. A 10-minute children's book chapter might clock in at 800–1,200 words.
Purpose. Skimming runs at 600–700 wpm. Reading to comprehend and retain runs slower than the average. Reading to critique or edit is slower still.
The formula is simple in either direction:
- Words → minutes: word count ÷ wpm = reading time
- Minutes → words: target minutes × wpm = word count
For a 10-minute silent read: 10 × 238 = 2,380 words.

Use this table when planning content length or checking how long your text will take to read.
| Reading time | Words (238 wpm, silent) | Words (130 wpm, speaking) |

| 1 minute | 238 words | 130 words |
| 2 minutes | 476 words | 260 words |
| 3 minutes | 714 words | 390 words |
| 4 minutes | 952 words | 520 words |
| 5 minutes | 1,190 words | 650 words |
| 7 minutes | 1,666 words | 910 words |
| 10 minutes | 2,380 words | 1,300 words |
| 15 minutes | 3,570 words | 1,950 words |
| 20 minutes | 4,760 words | 2,600 words |
| 30 minutes | 7,140 words | 3,900 words |
| 60 minutes | 14,280 words | 7,800 words |
Check any of these instantly by pasting your text into wordscounter.io — reading time and speaking time appear automatically alongside word count.
How different platforms calculate "X-minute read"
If you've ever noticed that Medium's read time estimate doesn't match what wordscounter.io shows, it's because platforms use different baselines:
| Platform | WPM baseline |
|---|---|
| wordscounter.io | 238 wpm (Brysbaert 2019 research) |
| Medium | 265 wpm |
| Dev.to | 275 wpm |
| Many generic calculators | 200 wpm |
A 2,380-word article will read as "10 min" on wordscounter.io, "9 min" on Medium, and "8–9 min" on Dev.to — same article, different badge. None is wrong; they just use different benchmarks.
Medium also adds 12 seconds per inline image to its estimate, which can meaningfully shift the reading time on image-heavy posts.
Why reading time matters for content creators
Adding a reading time estimate to your content isn't just a nice UI touch. A study by Simpleview Europe found that adding reading time badges increased engagement by up to 40%. Medium's internal research found that 7-minute reads capture the most attention — long enough to deliver real value, short enough not to lose readers.
For SEO purposes, knowing your reading time helps you:
- Hit the right length for your format. Blog posts in the 1,500–2,500 word range (roughly 6–10 minutes) perform well for competitive keywords.
- Plan podcast scripts and presentations. A 30-minute podcast episode needs ~3,900 words. A 5-minute conference talk needs ~650.
- Set reader expectations. Publishing a "12-minute read" on a simple topic signals padding. Publishing a "4-minute read" on a complex topic signals shallow coverage.
How to check reading time (free, instant)
Paste your text into wordscounter.io. It displays reading time (at 238 wpm) and speaking time (at 130 wpm) automatically — no buttons, no sign-up. Your text never leaves your browser.
If you're building a blog and want to add reading time badges, the calculation is straightforward: Math.ceil(wordCount / 238) gives you minutes rounded up.
Frequently asked questions
How many words is a 10-minute read?
At the standard adult reading speed of 238 wpm, a 10-minute read is approximately 2,380 words. At a slower or more cautious reading pace (200 wpm), it's around 2,000 words.
How many words is a 10-minute speech?
At a natural speaking pace of 130 wpm, a 10-minute speech is approximately 1,300 words. Professional speakers often aim for 125–150 wpm, which puts a 10-minute talk at 1,250–1,500 words.
Why does Medium show a different reading time than other tools?
Medium calculates read time at 265 wpm plus 12 seconds per image. Tools using 200–238 wpm will give a higher (longer) estimate for the same article.
How long is a 10-minute read for children?
It depends on age. Children ages 6–9 read at 60–120 wpm — a 10-minute read for them is roughly 600–1,200 words. Teens (12–14 years) approach adult speed at 170–200 wpm, putting a 10-minute read at 1,700–2,000 words.
Does text complexity change reading time?
Yes. Technical documentation, legal text, and academic papers slow reading speed to 100–150 wpm. For complex content, assume a 10-minute read is 1,000–1,500 words — not 2,380.
The bottom line
A 10-minute read is ~2,380 words for an average adult reading silently. A 10-minute speech or script is ~1,300 words. Text difficulty, reader age, and platform algorithm all shift that number.
Use wordscounter.io to check reading time and speaking time for any text — both figures appear instantly alongside word count, character count, and keyword density.
