Book Reading Time Calculator
Estimate how long it will take to finish a book based on page count, words per page, and your reading speed.
Estimated Reading Time
Book reading time depends on total word count and your reading speed.
Total Words = Pages × Words Per Page
Reading Time = Total Words / Reading Speed (WPM)
Typical words per page:
- Fiction paperback: 250–300 words/page
- Non-fiction: 300–350 words/page
- Textbook: 400–500 words/page
- Children’s book: 50–150 words/page
Average reading speeds:
- Slow reader: 150 WPM
- Average reader: 250 WPM
- Fast reader: 400 WPM
- Speed reader: 600+ WPM
Tips:
- Technical or dense material slows reading by 30–50%
- Audiobooks typically play at 150–160 WPM (1x speed)
- Reading before bed may be slower due to fatigue
