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: 90,566 words, 5,473 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
90,566 ÷ 250 wpm   = 362 min   → 6h 02m
words ÷ density         = extent
90,566 ÷ 275 w/pp  = 329 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 90,566 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: 90,566 words ÷ 250 words per minute = 362 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 straightforward — middle school level: Flesch–Kincaid puts it at grade 7.9, Gunning fog at 11, Coleman–Liau at 9. The Flesch reading-ease score of 67.6 is fairly typical of adult fiction.

The mechanics behind that: sentences average 16.5 words (modern prose tends to run 15–20), and 11% of words are three syllables or longer. Its vocabulary is unusually varied — 9,017 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 Secret Agent?

90,566 words in the Project Gutenberg edition, made up of 9,017 distinct words across 5,473 sentences. That is longer than 46% of the books measured on this site.

How long does it take to read The Secret Agent?

About 6h 02m at an average adult reading speed of 250 words per minute. A slower reader at 150 wpm would need roughly 10h 04m; a fast reader at 400 wpm about 3h 46m.

What reading level is The Secret Agent?

It scores 7.9 on the Flesch–Kincaid grade scale — straightforward — middle school level. Its Flesch reading-ease score is 67.6, sentences average 16.5 words, and 11% of its words run to three syllables or more.

How many pages is The Secret Agent?

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, 90,566 words works out to roughly 329 pages.

Colophon

Measured from the Project Gutenberg plain-text edition, ebook no. 974, with Gutenberg’s header and licence footer struck before counting. 90,566 words, 5,473 sentences, 9,017 distinct forms. No text of the work is set anywhere on this site — only measurements of it.

The extent of 329 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.
