See how long to read a book (or any big section) from page count, words per page, and your pace. You get total hours and how many days it takes at your usual daily reading time.
Pick a popular book or common page count for instant results, or choose Custom to enter your own values below
Typical: 250 words/page for fiction, 300-400 for non-fiction
💡 Quick tip: Not sure of your reading speed? Start with "Average (250 words/min)" - most people fall in this range. You can always adjust later!
📚 Remember: Reading speed varies by book type. You'll read a thriller faster than a dense textbook, so adjust your speed accordingly!
How long does it take to read Harry Potter? The Bible? Atomic Habits? Pick a popular book from the quick-pick list (or enter your own page count) and the Reading Time Calculator shows total hours plus how many days that takes at your daily reading habit.
Book presets use canonical word counts, not page counts, so a paperback Bible and a hardcover Bible give the same answer. For custom books, you can adjust words-per-page (250 for most fiction, 300 to 400 for dense non-fiction) to keep the estimate honest.
Treat the finish date as a fair estimate, not a promise. The calculator does not know about skipped weekends or rereads. Useful for book club deadlines, syllabus planning, or deciding whether Don Quixote really fits your year (spoiler: about 30 hours at average pace).

Our calculator uses proven formulas and up-to-date data to give you accurate results. Here's a transparent look at the methodology behind your calculation.
The Formula
Total Words = Pages × Words Per PageReading Time (minutes) = Total Words ÷ Reading SpeedDays to Finish = Reading Time ÷ Minutes Per DayWe use your reading speed (words per minute) and daily reading time to give you accurate estimates. The average person reads 200-250 words per minute, but we let you customize it!
You tell us: book pages, your reading speed, words per page, and how much time you can read daily. Simple!
We multiply pages by words per page to get total words, then divide by your reading speed. Math magic! ✨
We show you total reading time, days to finish, and fun scenarios like 'what if I read more?' 📚
