How this is worked out

  1. The Project Gutenberg plain-text edition is fetched, then Gutenberg's header and licence footer are struck at the *** START *** and *** END *** markers. Nothing is taken from a publisher's listing.
  2. What remains is counted as that edition sets it: 138,937 words, 6,956 sentences, syllables by vowel-group heuristic.
  3. Words are divided by a stated reading rate. This page's headline uses 250 words a minute; a duration printed without its rate cannot be checked, so the rate travels with every figure and the table below runs 150–450 wpm.
  4. Minutes are rounded once, to the nearest minute, and set as h:mm. Nothing on this page is rounded twice.
  5. The page extent is a courtesy conversion at 275 words to the page — a typesetting figure, not a property of the book.
words ÷ rate            = minutes
138,937 ÷ 250 wpm   = 556 min   → 9h 16m
words ÷ density         = extent
138,937 ÷ 275 w/pp  = 505 pages

How long it takes to read, by reading speed

Most adults read prose at 200–300 words per minute. Reading speed varies far more between people than most reading-time estimates admit, so here is the whole range.

Reading it in evenings

The same 138,937 words, divided by the habit rather than by the hour — and then a rate of your own, if 250 wpm is not yours.

Is it a hard read?

Four different readability formulas agree it is moderate — early high school level: Flesch–Kincaid puts it at grade 8.9, Gunning fog at 11.8, Coleman–Liau at 9.1. The Flesch reading-ease score of 66.8 is fairly typical of adult fiction.

The mechanics behind that: sentences average 20 words (modern prose tends to run 15–20), and 9.5% of words are three syllables or longer. Its vocabulary is unusually varied — 13,833 distinct words, or 9.96% of the total.

A caution about all of this: readability formulas measure sentence and word length, nothing more. They cannot see irony, dialect, allusion or an unreliable narrator. A book can score as "easy" and still be genuinely difficult to follow.

The second question

What people ask once the duration is on the table.

How many words are in The Man Who Did the Right Thing?

138,937 words in the Project Gutenberg edition, made up of 13,833 distinct words across 6,956 sentences. That is longer than 71% of the books measured on this site.

How long does it take to read The Man Who Did the Right Thing?

About 9h 16m at an average adult reading speed of 250 words per minute. A slower reader at 150 wpm would need roughly 15h 26m; a fast reader at 400 wpm about 5h 47m.

What reading level is The Man Who Did the Right Thing?

It scores 8.9 on the Flesch–Kincaid grade scale — moderate — early high school level. Its Flesch reading-ease score is 66.8, sentences average 20 words, and 9.5% of its words run to three syllables or more.

How many pages is The Man Who Did the Right Thing?

Page counts depend entirely on the edition — font, trim size and margins all change them, which is why this site measures words instead. At a typical trade-paperback density of about 275 words per page, 138,937 words works out to roughly 505 pages.

Colophon

Measured from the Project Gutenberg plain-text edition, ebook no. 45451, with Gutenberg’s header and licence footer struck before counting. 138,937 words, 6,956 sentences, 13,833 distinct forms. No text of the work is set anywhere on this site — only measurements of it.

The extent of 505 pages is a conversion at 275 words to the page, not this edition’s foliation: a page count belongs to a typesetting, never to a book. Reading time assumes 250 words a minute and is stated with its rate everywhere it appears.
