How Long Will It Take to Read?
Estimate reading time by word count, page count, or book length. Adjust for reading speed and material difficulty.
Average Reading Speeds
Average adult: 200-250 words per minute (wpm). College student: 300 wpm. Speed reader: 400-700 wpm. World record: 25,000 wpm (with comprehension). Material difficulty dramatically affects effective speed — dense academic text reads at 50-60% of your fiction speed. A 300-page novel takes about 5 hours at average speed; a 300-page textbook takes 8-10 hours.
Reading Speed by Format
Physical books and e-readers produce similar reading speeds. Reading on a phone is 10-15% slower due to smaller text and more frequent page turns. Audiobooks at 1x speed are equivalent to about 150 wpm. Most audiobook listeners use 1.25-1.5x speed (190-225 wpm) with no comprehension loss.
Bill Gates reads approximately 50 books per year at an estimated speed of 750 wpm with exceptional comprehension. Warren Buffett reads 5-6 hours per day. The correlation between reading habits and professional success is well-documented — CEOs read an average of 60 books per year vs 2-3 for the average American.
