How this is worked out
- 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. - What remains is counted as that edition sets it: 134,499 words, 6,937 sentences, syllables by vowel-group heuristic.
- 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.
- Minutes are rounded once, to the nearest minute, and set as h:mm. Nothing on this page is rounded twice.
- 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 134,499 ÷ 250 wpm = 538 min → 8h 58m words ÷ density = extent 134,499 ÷ 275 w/pp = 489 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 speed | Total time | At 30 min/day | At 1 hour/day |
|---|---|---|---|
| Slow / careful (150 wpm) | 14h 57m | 30 days | 15 days |
| Below average (200 wpm) | 11h 12m | 23 days | 12 days |
| Average adult (250 wpm) | 8h 58m | 18 days | 9 days |
| Fast (300 wpm) | 7h 28m | 15 days | 8 days |
| Very fast (450 wpm) | 4h 59m | 10 days | 5 days |

Reading it in evenings
The same 134,499 words, divided by the habit rather than by the hour — and then a rate of your own, if 250 wpm is not yours.

Is it a hard read?
Four different readability formulas agree it is moderate — early high school level: Flesch–Kincaid puts it at grade 8.1, Gunning fog at 10.9, Coleman–Liau at 7.9. The Flesch reading-ease score of 71.5 sits in genuinely plain-English territory.
The mechanics behind that: sentences average 19.4 words (modern prose tends to run 15–20), and 7.9% of words are three syllables or longer. Its vocabulary is moderately varied — 9,733 distinct words, or 7.24% 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.

What people ask once the duration is on the table.
How many words are in The Story of My Life?

How many pages is The Story of My Life?
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, 134,499 words works out to roughly 489 pages.

Measured from the Project Gutenberg plain-text edition, ebook no. 2397, with Gutenberg’s header and licence footer struck before counting. 134,499 words, 6,937 sentences, 9,733 distinct forms. No text of the work is set anywhere on this site — only measurements of it.
The extent of 489 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.
