How long does it take to read Stiff?
At 311 pages, Stiff is a fairly long book. Expect about 5 hours 40 minutes of reading to finish it, based on 250 words per page and an average reading speed of 230 words per minute. A fast reader will go quicker; a careful read (or reading in a second language) will take longer.
At 30 minutes a day, that is about 12 days of reading. At the median pace of Vread readers, 72 pages per reading day, it takes 5 reading days. For a book of this length (250 to 399 pages), Vread readers who finish it take a median of 4.7 days between the first and the last checkpoint (Vread Reading Barometer 2026).

The Vread challenge: 9 checkpoints
- Checkpoint 1, page 35
- Checkpoint 2, page 69
- Checkpoint 3, page 104
- Checkpoint 4, page 138
- Checkpoint 5, page 173
- Checkpoint 6, page 207

In Vread, Stiff is split into 9 checkpoints, one every 35 pages or so. At each checkpoint, a question covers the passage you have just read: a correct answer validates the step, and your progress moves forward like a training plan.
The challenge: validate all 9 checkpoints through to the last page. No giant quiz at the end, no summary to copy out: short questions along the way that prove the book was actually read. It also works as a reading quiz to check your understanding before a test.
Also available in French on Vread.

The answer is in the text: reply in the app.

This is not a question from Stiff: to avoid spoilers, the real questions stay in the app.
