Reading time for a specific page count

Each page adds how many days the count takes at your daily habit, and books that are about that long.

One sitting (up to 30 pages)

An afternoon or two evenings (31–120 pages)

Novel length (121–350 pages)

A reading project (over 700 pages)

1,000 pages

Why your real number will differ

This table assumes about 250 words per page (the average for most novels). Dense hardbacks, textbooks, and footnote-heavy pages contain more, so they take longer to read. Pausing, rereading, and interruptions can also add to the estimated reading time.
