Did this tool work for you?
How to use this calculator
Divide the number of words you read by the number of minutes it took. Then divide the total book word count by your WPM to get reading time in minutes.
- 1
Read a passage for a set time and count the words (or use a known word count), then enter both numbers.
- 2
Enter your book length in pages and the approximate words per page (250 is standard for most novels).
- 3
Read your WPM, how it compares to the average, and how long the book will take you.
Frequently asked questions
What is the average reading speed?
The average adult reads approximately 238 words per minute for non-fiction material. Speed readers can reach 400–700 WPM with comparable comprehension.
How many words are on a typical book page?
Most paperback novels average 250–300 words per page. Textbooks often have fewer due to diagrams and spacing. You can count a sample page for accuracy.
Can I improve my reading speed?
Yes — techniques include reducing subvocalization (silently pronouncing words), using a pointer to guide your eyes, and practicing with progressively longer timed sessions.
