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: 1,275,777 words, 48,531 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
1,275,777 ÷ 250 wpm   = 5103 min   → 85h 03m
words ÷ density         = extent
1,275,777 ÷ 275 w/pp  = 4,639 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.

Is it a hard read?

Four different readability formulas agree it is moderate — early high school level: Flesch–Kincaid puts it at grade 9.8, Gunning fog at 12.6, Coleman–Liau at 6.5. The Flesch reading-ease score of 71.8 sits in genuinely plain-English territory.

The mechanics behind that: sentences average 26.3 words (modern prose tends to run 15–20), and 5.2% of words are three syllables or longer. Its vocabulary is fairly repetitive — 22,812 distinct words, or 1.79% 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 Diary of Samuel Pepys — Complete?

1,275,777 words in the Project Gutenberg edition, made up of 22,812 distinct words across 48,531 sentences. That is longer than 100% of the books measured on this site.

How long does it take to read The Diary of Samuel Pepys — Complete?

About 85h 03m at an average adult reading speed of 250 words per minute. A slower reader at 150 wpm would need roughly 141h 45m; a fast reader at 400 wpm about 53h 09m.

What reading level is The Diary of Samuel Pepys — Complete?

How many pages is The Diary of Samuel Pepys — Complete?

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, 1,275,777 words works out to roughly 4,639 pages.

Colophon

Measured from the Project Gutenberg plain-text edition, ebook no. 4200, with Gutenberg’s header and licence footer struck before counting. 1,275,777 words, 48,531 sentences, 22,812 distinct forms. No text of the work is set anywhere on this site — only measurements of it.

The extent of 4,639 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.
