About reading speed
Reading speed is measured in words per minute (wpm): how many words you process in 60 seconds at a comfortable pace with adequate comprehension. It is one of the most studied numbers in cognitive psychology because it underpins everything from study planning to exam time limits. This tool times you against a passage of known length and reports your wpm, plus rough projections for pages per hour and books per year.
The honest headline is that typical adults read far slower than popular "speed reading" courses imply. A 2019 meta-analysis by Marc Brysbaert, pooling 190 studies, put the average English silent reading rate at roughly 238 wpm for non-fiction and 260 wpm for fiction. College-level readers land near 250 to 350 wpm. Genuine reading (where the eyes fixate on essentially every word) tops out around 400 to 600 wpm even for trained readers.
Crucially, speed and comprehension trade off against each other. Beyond roughly 500 wpm, you are no longer reading every word; you are skimming and sampling, and recall of detail drops sharply. For material you must understand and retain (contracts, textbooks, technical docs) accuracy matters more than raw pace, so treat a high wpm as useful only when paired with a comprehension check.
How it works: the formula
Words per minute is simply the word count divided by the elapsed time converted to minutes:
wpm = words / (minutes + seconds / 60) pages_per_hour = wpm x 60 / words_per_page (250 wpp assumed) books_per_year = pages_per_hour x daily_minutes / pages_per_book
- words = the exact length of the passage you read (use a known count for a fair test).
- minutes + seconds/60 = total reading time expressed as a decimal number of minutes.
- words_per_page = roughly 250 to 300 for a typical paperback; this tool assumes 250.
- Comprehension is not in the formula: confirm it separately with a few recall questions.
Worked example
Suppose you read a 2,000-word article and it took 8 minutes exactly.
- Convert time: 8 minutes and 0 seconds = 8.0 minutes.
- Divide: 2000 / 8.0 = 250 wpm.
- Pages per hour: 250 x 60 / 250 = 60 pages per hour at 250 words per page.
- Category: 250 wpm sits right at the average-adult mark.
Reference table: reading-speed bands
| Band | Speed (wpm) | Who reads here | Comprehension |
|---|---|---|---|
| Slow / learning | under 150 | Early readers, second-language, dense text | High but effortful |
| Below average | 150-250 | Casual adult reading difficult material | Good |
| Average adult | 250-350 | Most adults, typical prose | Good |
| Fast | 350-500 | Trained, well-practised readers | Good on familiar topics |
| Speed reader | 500-700 | Skilled skimmers, light material | Falling |
| Skimming | 700+ | Sampling, not full reading | Low for detail |
Common pitfalls
- Testing on too-short a passage. A 100-word snippet gives noisy results because a single pause skews the rate. Use at least 500 to 1,000 words for a reliable figure.
- Skimming during the test. If you race through to post a big number, you measure skimming speed, not reading speed. Read as you normally would for understanding.
- Ignoring comprehension. A wpm figure is meaningless without retention. Always answer a few questions afterward; if you cannot, your effective speed is lower.
- Comparing print to screen figures. Most people read 10 to 30 percent slower on screens than on paper for the same content, so compare like with like.
- Believing 1,000+ wpm claims. Courses promising five-figure reading speeds rely on skimming. Eye-tracking research shows the physical limit of genuine word-by-word reading is well under 1,000 wpm.
