How long does it take to read John Adams?
At 880 pages, John Adams is a doorstopper. Expect about 16 hours 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 32 days of reading. At the median pace of Vread readers, 72 pages per reading day, it takes 13 reading days. For a book of this length (600 pages or more), Vread readers who finish it take a median of 6.4 days between the first and the last checkpoint (Vread Reading Barometer 2026).

In Vread, John Adams is split into 25 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 25 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.
