How we measured it
Method: audiobook estimate. Estimated from the unabridged recordings narrated by Ruth Wilson at 155 words a minute, confirmed by at least two of Audible, Libro.fm and Penguin Random House. The Amber Spyglass recording ends with a bonus conversation between Wilson and Pullman, so its estimate runs a little long. The older full-cast recordings and The Book of Dust aren't included.
