Reading Time by Speed

Reading time: minutes = words ÷ WPM

Reading speed gets measured in WPM (words per minute), and the math is just time = total_words / WPM. Most adults reading silently land somewhere between 200 and 250 WPM while still following everything. Push into speed reading and you can hit 500 to 1,000 WPM, but you give up depth to gain ground. Anne Jones, who holds the world record, has been credited with 4,700+ WPM in demonstrations, although whether comprehension survives at those speeds is something independent tests still argue about. What really holds you back is subvocalization, the inner voice that sounds out each word, and it tops out near the rate of speech, around 300 WPM. So a 3,000-word article runs 15 minutes at 200 WPM and 7.5 minutes at 400 WPM. Once you climb past roughly 600 WPM on material you don't already know, comprehension falls off fast.

Applications

Planning study schedules for ENEM, vestibular and competitive exams. Sizing up how long a technical or academic reading load will actually take. Setting audiobook playback at 1.5×–2× speed. Adding "X-minute read" labels in content marketing. And pacing courses or e-learning modules against realistic completion times.

FAQ

Does faster reading always reduce comprehension? Once you go past the ceiling you've actually trained for, yes, and recall drops in ways you can measure. But in a familiar area, say your own field of work, you can speed up and not lose much.

How do I reduce subvocalization? Run a pointer along the line with your finger or a pen, widen each fixation so you take in 3–4 words per saccade, and drill with timed passages. Getting rid of it completely isn't realistic, and you wouldn't want to anyway, since you'd lose comprehension.

What WPM should I aim for? For an adult, 300–400 WPM is a solid target you can actually hold. Go faster than that and you're skimming, not reading deeply.
