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: 561,352 words, 94,407 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
561,352 ÷ 250 wpm   = 2245 min   → 37h 25m
words ÷ density         = extent
561,352 ÷ 275 w/pp  = 2,041 pages

How long it takes to read, by reading speed

Is it a hard read?

Four different readability formulas agree it is easy — upper primary level: Flesch–Kincaid puts it at grade 5.3, Gunning fog at 7.9, Coleman–Liau at 6.8. The Flesch reading-ease score of 67.3 is fairly typical of adult fiction.

The mechanics behind that: sentences average 5.9 words (modern prose tends to run 15–20), and 13.9% of words are three syllables or longer. Its vocabulary is moderately varied — 28,798 distinct words, or 5.13% 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.

What people ask once the duration is on the table.

The rest of Boase, Frederic’s shelf, measured

Colophon

Measured from the Project Gutenberg plain-text edition, ebook no. 55059, with Gutenberg’s header and licence footer struck before counting. 561,352 words, 94,407 sentences, 28,798 distinct forms. No text of the work is set anywhere on this site — only measurements of it.

The extent of 2,041 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.
