How many words is When Breath Becomes Air?
When Breath Becomes Air is about 63,250 words, estimated from its 230 pages at about 275 words a page. At 250 words a minute, that comes to 4 hours 13 minutes.
Most reading-time sites default to 300 words a minute. The best evidence we could find, a 2019 meta-analysis of 190 studies by Marc Brysbaert, puts silent adult reading of English prose closer to 238 words a minute for non-fiction and 260 for fiction. We use 250. It is slower than the number you will see elsewhere, and it is closer to how people actually read.
This is still a model, not a measurement. When enough ReadersGuild readers have finished When Breath Becomes Air, we will replace this estimate with the time they actually took.
