This reading time calculator turns a word count into an honest estimate of how long a piece will take to read. Paste any text and it counts the words for you, or type a word count directly — then it shows the time at a slow, average, and fast pace, plus any speed you choose with the slider.
How long does it take to read…
Estimates at the average adult silent-reading pace of about 238 words per minute:
| Word count | At 238 wpm | Typical example |
|---|---|---|
| 500 words | about 2 min | a short blog post |
| 1,000 words | about 4 min | a standard article |
| 2,500 words | about 11 min | a long-form article |
| 5,000 words | about 21 min | a magazine feature |
| 10,000 words | about 42 min | an academic paper |
| 50,000 words | about 3½ hours | a short novel |
| 100,000 words | about 7 hours | a full-length novel |
How reading time is calculated
The math is simple: reading time = word count ÷ reading speed (in words per minute). One thousand words at 238 wpm is just over four minutes; the same thousand words at 400 wpm is two and a half. The only variable that really moves the estimate is the speed you read at — which is why this tool lets you set it rather than guessing for you.
What reading speed should I use?
For adults reading English silently, the average is about 238 words per minute, with most people between 200 and 300 wpm. Use roughly 150 wpm for careful or unfamiliar material, 238 for typical reading, and 400–600 for a skilled or skimming-aware reader. Not sure where you land?

Frequently asked questions
How long does it take to read 10,000 words?
At the average adult pace of about 238 words per minute, 10,000 words takes roughly 42 minutes. A fast reader at 400 wpm finishes in about 25 minutes.
How is reading time calculated?
Reading time is the word count divided by reading speed in words per minute. For example, 1,000 words at 238 wpm is about 4 minutes. This calculator counts the words for you and applies several speeds at once.
What's the average reading speed?
For adults reading silently, about 238 words per minute, with most people falling between 200 and 300 wpm. Children and older adults tend to read more slowly; see average reading speed by age.
How long does it take to read a book?
A typical 90,000-word novel takes about 6 hours 18 minutes at the 238 wpm average, or under 4 hours at 400 wpm. A denser 120,000-word book runs closer to 8½ hours at the average pace.
