Pages, words and editions
Every number here assumes 250 words per page — the manuscript standard that school papers and publishers use. Real books wander: a dense paperback can hold 350 words on a page, a large-print edition 150, and an illustrated guide fewer still. The honest way to compare books is therefore words, not pages, which is why the 133-classic reading-time shelf times every title from its word count. For 100 pages the working figure is 25,000 words — close enough to plan an evening or a week around.
Sessions and habit math
One or two sittings, honestly told: at a careful 150 wpm it is 2 hours and 47 minutes; at a fast 350 wpm, 1 hour and 11 minutes. The whole question is whether tonight is a reading night. Measure your real pace once with the reading speed test and every estimate on this site becomes yours.
