One timed passage, three comprehension questions, about two minutes. Your words per minute against the adult average, and what it means for the books on your list.
261 words · about 1 to 2 minutes
Not your fastest pace, the pace you would actually use. Three short questions afterwards check that the speed was real. Nothing is recorded or sent anywhere.
Bands, not verdicts. Reading speed varies with material, fatigue, and language, and a single test places you roughly:
| Under 150 wpm | Careful | Dense material, second-language reading, note-taking pace |
| 150–250 wpm | Average | Most adults; the research average is 238 |
| 250–350 wpm | Brisk | Comfortably above average with solid comprehension |
| 350–500 wpm | Fast | Top few percent, if comprehension holds |
| 500+ wpm | Claimed, rarely real | Comprehension almost never survives here |
Know your number? The reading time calculator takes a custom speed and turns any book or document into a time estimate.
Any test that measures only elapsed time rewards skimming, and skimming inflates the number without moving anything into memory. The three questions after the passage are deliberately answerable by anyone who genuinely read it, and genuinely hard to guess. A high speed with low comprehension is not a reading speed.
The deeper honesty: research keeps finding that speed and depth trade off past a fairly ordinary pace. If your reading list outruns your reading hours, the durable fix is rarely reading faster. It is adding hours your eyes do not have, which is what listening does, and why the result screen compares your speed against narrated audio at 1x and 2x.
The adult average for silent reading of non-fiction is around 238 words per minute, with most adults falling between 150 and 300. Below 150 is common for dense or technical material and for reading in a second language. Above 350 with full comprehension puts you in the top few percent of readers.
Accurate enough to place you in a band, not to certify a number. One passage of one difficulty, read once, measures that passage. This test includes comprehension questions because a speed with nothing retained is not a reading speed, it is a scrolling speed. Take it two or three times for a steadier estimate.
Modestly, honestly. Reading more, especially in the same subject, builds the vocabulary and familiarity that speed actually comes from. Claims of tripling your speed through eliminating subvocalization have not survived controlled studies: past roughly 400 to 500 words per minute, comprehension drops sharply for almost everyone.
The research consensus is that the trade-off is real and unavoidable: faster eye movement past a certain point means shallower processing. Skimming has legitimate uses, like triage and review, but for material you need to understand and remember, there is no free speed. That is precisely why audio, which runs in otherwise-dead hours, is often the better answer than pushing your eyes harder.
Per word, usually yes: narration runs near 155 words per minute against a 238 average for silent reading, though playback speed closes the gap, and 2x listening is faster than most people read. Per week, listening often wins, because it works during commutes, workouts, and chores, hours where reading is impossible.
