What this reading time calculator can answer

- Whether you can finish a book before a specific deadline
How to use the reading time calculator
- Choose your reader type — slow, average, or quick — or select custom and enter your own reading speed. If you're unsure, the average speed of about 0.5 pages per minute works well for most fiction.
- Enter the book's total page count. You can find this on the book's cover, copyright page, or on Goodreads.
- Click Calculate to see the total reading time in hours and minutes.
- Optional: enter your daily reading time or the number of days you want to finish in to get a personalized daily reading plan.
Calculating reading time — an example
Say you have a 300-page textbook to finish in 40 days (about two months of weekday study). You read dense material at roughly 0.33 pages per minute — about 3 minutes per page.
Enter 0.33 pages/min and 300 pages. The calculator shows a total reading time of about 15 hours and 9 minutes. Then enter 40 days in the "Days to finish" field.
The result: you need about 22 minutes of reading per day, or roughly 7.5 pages daily. Small, consistent sessions beat cramming — and tools like Bookyno help you track those sessions over time.
Frequently asked questions
How long does it take to read 30 pages?

How long does it take to read The Great Gatsby?
The Great Gatsby has about 180 pages. At an average reading speed, you'll need roughly 6 hours total. Reading one hour per day, you could finish it in about 6 days.
How much should I read per day to finish 52 books a year?
Assuming an average book length of 300 pages and a reading speed of 0.5 pages per minute, you'd need about 1.5 hours of reading per day. Reading faster or choosing shorter books reduces that daily commitment.
How do I find my reading speed?
Time yourself reading a few pages of a typical book for you, then divide pages read by minutes elapsed. For example, 5 pages in 10 minutes equals 0.5 pages per minute. Use our reading speed calculator to get your pace instantly.
