Why your real number will differ

This table assumes about 250 words per page (the average for most novels). Dense hardbacks, textbooks, and footnote-heavy pages contain more, so they take longer to read. Pausing, rereading, and interruptions can also add to the estimated reading time.

For the reasoning behind these numbers, read how long it takes to read 100 pages →. To replace the average with your own measured pace, take the Reading Speed Test first, then return to the Reading Time Calculator.
