Reading Time Calculator
Estimate how long it will take to read a book, and plan your daily reading.
Total reading time
Reader type presets fill a typical speed. Choose “Custom” to enter your own.
Book reading duration
References
- Total time (min) = pages ÷ (pages/min).
- Unit links: 1 hour = 60 min; 1 week ≈ 7 days; 1 month ≈ 30 days.
- Typical adult reading speed ≈ 0.5 pages/min (useful as an “average” preset).
Use this Reading Time Calculator to estimate how long it may take to finish a book and how many pages you can read each day based on your reading speed.
Reading Time Calculation Method
Total reading time = total pages ÷ reading speed
If reading speed is entered in pages per minute:
Pages per hour = pages per minute × 60
For a daily reading plan:
Pages per day = reading speed × daily reading time
Days to finish = total pages ÷ pages per day
Example
Suppose a book has 240 pages and you read at 0.5 pages per minute.
Total reading time = 240 ÷ 0.5 = 480 minutes
480 minutes = 8 hours
If you read for 30 minutes each day:
Pages per day = 0.5 × 30 = 15 pages
Days to finish = 240 ÷ 15 = 16 days
At this pace, the book would require approximately 8 hours of active reading or about 16 days at 30 minutes per day.
Important Notes
- Page-based reading speed is only an estimate because books differ in page size, font, spacing, illustrations, and words per page.
- Reading speed also varies with topic difficulty, language fluency, concentration, and reading purpose.
- Textbooks and technical material may require additional time for notes, exercises, rereading, and review.
- Reader presets are planning shortcuts. Use your own measured reading speed when available.
- For articles or other text with a known word count, words-per-minute calculations are generally more comparable than pages per minute.
