How long your book takes to read
Readers increasingly want to know what they are committing to before they start. Putting an honest reading time in your book description, or on a book club page, removes friction and sets expectations. It also helps you sanity-check whether a chapter is the right length.
How fast do people actually read?
Adult silent reading of fiction averages around 240 to 260 words per minute. Non-fiction that requires thinking drops to roughly 180 to 200. Reading aloud, which is what an audiobook narrator does, sits near 150 words per minute. Speed readers claim far more, but comprehension falls sharply above about 400.
How long should a chapter be?
Most commercial fiction chapters run 1,500 to 4,000 words, which is roughly 6 to 16 minutes of reading. Thrillers trend shorter because short chapters create momentum, while literary and epic fantasy chapters run longer. A useful test is whether a chapter fits into one sitting, such as a commute.
Why put reading time in your description?
It answers a real question a browsing reader has, and it works particularly well for novellas, short non-fiction and serial fiction, where "a two-hour read" is a selling point rather than a limitation.
