Test where you are
Two things decide how much of a book you get through: the pace you can take words at, and how many of them you already know. Each is measured separately here, because they move independently — and because an average of the two would describe nobody.
Take either one, both, or neither. Nothing here needs an account, and the numbers are yours — once you have them, every book on the site is recosted in hours at your pace rather than at a generic one.

How fast do you read?
Five passages in a word-at-a-time reader, each faster than the last, and a question about a detail after every one.
- Stages5, from 180 to 480 words a minute
- The catchThe question is what makes it a reading speed rather than a skimming speed — you only keep a stage you actually understood
- You getThe fastest pace you still read at, and every book on the site recosted in hours at it
About ninety seconds
How many words do you know?
15 words, each sampled from a different band of how often it actually appears in the library — from the common to the genuinely obscure.
- Drawn from18.4 million words of classic literature, not a generic frequency list
- The catchSaying you are unsure costs you nothing. Guessing makes the estimate worse, not better
- You getAn estimate of your vocabulary, and the books that would grow it fastest
Neither is a party trick. The reader uses both: it times every word against how common it is and how many times you have met it, so a measured vocabulary changes how the book is paced — and a measured speed changes what every book on this site claims it will cost you in hours. How that arithmetic works.
