How Fast Can You Actually Read?
Speed only counts if you understood it. This test finds the fastest speed where your answers stay right, and the point where they start to slip.
How it works
- Press start. After a 3-second countdown, two sentences flash past, one word at a time.
- Tap the one you just read. If it went by too fast, say you don’t know: that beats a guess and makes your result more accurate.
- Right answers push the speed up, a miss pulls it down, and every answer narrows the range. You watch the graph close in on your number.
Your perfect speed is 450 words per minute.
Answers held up to 450 and started to slip around 500.
Rounds
Speeds are reader settings, the same numbers the slider uses on this site and in the app. Every run uses passages you have not seen.
Questions about reading speed
Does reading faster hurt comprehension?
Past a certain speed it does, and that speed is different for everyone and for every kind of text. Below it, comprehension holds. This test finds the point by raising the speed while you keep answering correctly, then closing in from both sides once you miss.
What is a good reading speed?
Most adults read ordinary text at 200 to 300 words per minute. With RSVP, where words appear one at a time in a fixed spot, many people hold full comprehension at 350 to 500 on easy text. Dense material needs a lower setting. See the guide on average reading speed.
How does the test decide my speed?
It runs a search. It starts at 350 words per minute and jumps up while you keep answering correctly, with bigger jumps when you answer quickly. Your first miss sets an upper limit. From then on each round tests the middle of the range your limit could still be in, so every answer cuts that range down, the way a binary search does. It also knows a right answer can be a lucky one-in-three guess, so a single fluke does not throw it off, and it trusts your answers more if you use the “I don’t know” button instead of guessing. Your ceiling is where your answers start to slip. Your perfect speed sits about a tenth under it.
