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: 79,968 words, 1,595 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
79,968 ÷ 250 wpm   = 320 min   → 5h 20m
words ÷ density         = extent
79,968 ÷ 275 w/pp  = 291 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 79,968 words, divided by the habit rather than by the hour — and then a rate of your own, if 250 wpm is not yours.

Worked from the text: 79,968 words ÷ 250 words per minute = 320 minutes of reading, divided by the daily habit and rounded up to whole days.

Is it a hard read?

Four different readability formulas agree it is very difficult — postgraduate level: Flesch–Kincaid puts it at grade 19.6, Gunning fog at 22.6, Coleman–Liau at 10.1. The Flesch reading-ease score of 43.6 is heavy going by modern standards.

The mechanics behind that: sentences average 50.1 words (modern prose tends to run 15–20), and 6.3% of words are three syllables or longer. Its vocabulary is unusually varied — 9,966 distinct words, or 12.46% 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 Paradise Lost?

79,968 words in the Project Gutenberg edition, made up of 9,966 distinct words across 1,595 sentences. That is longer than 39% of the books measured on this site.

How long does it take to read Paradise Lost?

About 5h 20m at an average adult reading speed of 250 words per minute. A slower reader at 150 wpm would need roughly 8h 53m; a fast reader at 400 wpm about 3h 20m.

What reading level is Paradise Lost?

It scores 19.6 on the Flesch–Kincaid grade scale — very difficult — postgraduate level. Its Flesch reading-ease score is 43.6, sentences average 50.1 words, and 6.3% of its words run to three syllables or more.

How many pages is Paradise Lost?

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, 79,968 words works out to roughly 291 pages.

Colophon

Measured from the Project Gutenberg plain-text edition, ebook no. 20, with Gutenberg’s header and licence footer struck before counting. 79,968 words, 1,595 sentences, 9,966 distinct forms. No text of the work is set anywhere on this site — only measurements of it.

The extent of 291 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.
