Reading an entire book in a matter of hours may seem daunting, but it all comes down to simple math. The average adult reads around 200-400 words per minute. The average novel ranges between 60,000 and 100,000 words total. If your reading speed is right in the middle of the pack at 300 words per minute, and you’re reading a middle-of-the-pack novel at around 80,000 words, you’ll be able to knock it out in around five hours or less.
