How this estimate works
Time = pages × words per page ÷ reading speed. A typical paperback page holds about 250–300 words, so we use 275. The 238 wpm average comes from a 2019 review of 190 reading studies by psychologist Marc Brysbaert; fiction is read a little faster, at about 260 wpm. Your real time also depends on the font, the page size and how dense the writing is, so treat it as a planning figure. To get a figure for you rather than the average, take the 60-second reading speed test; your result then appears as “My speed” in the calculator above.
