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: 36,471 words, 1,918 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
36,471 ÷ 250 wpm   = 146 min   → 2h 26m
words ÷ density         = extent
36,471 ÷ 275 w/pp  = 133 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.

The same 36,471 words, divided by the habit rather than by the hour — and then a rate of your own, if 250 wpm is not yours.

Average adult prose speed is 200–300 wpm. Not sure? Time yourself on one page.

Is it a hard read?

Four different readability formulas agree it is moderate — early high school level: Flesch–Kincaid puts it at grade 8.8, Gunning fog at 11.6, Coleman–Liau at 9.8. The Flesch reading-ease score of 65.8 is fairly typical of adult fiction.

The mechanics behind that: sentences average 19 words (modern prose tends to run 15–20), and 9.9% of words are three syllables or longer. Its vocabulary is unusually varied — 5,193 distinct words, or 14.24% 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 Time Crime?

36,471 words in the Project Gutenberg edition, made up of 5,193 distinct words across 1,918 sentences. That is longer than 13% of the books measured on this site.

How long does it take to read Time Crime?

About 2h 26m at an average adult reading speed of 250 words per minute. A slower reader at 150 wpm would need roughly 4h 03m; a fast reader at 400 wpm about 1h 31m.

What reading level is Time Crime?

It scores 8.8 on the Flesch–Kincaid grade scale — moderate — early high school level. Its Flesch reading-ease score is 65.8, sentences average 19 words, and 9.9% of its words run to three syllables or more.

How many pages is Time Crime?

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, 36,471 words works out to roughly 133 pages.

The rest of Piper, H. Beam’s shelf, measured

Colophon

Measured from the Project Gutenberg plain-text edition, ebook no. 18151, with Gutenberg’s header and licence footer struck before counting. 36,471 words, 1,918 sentences, 5,193 distinct forms. No text of the work is set anywhere on this site — only measurements of it.

The extent of 133 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.
