The median audiobook in our dataset runs 9.7 hours; the average is 10.8 — the average sits higher because a small number of very long titles stretches the tail. 81% of everything we measured lands between 4 and 16 hours.

Quartiles put numbers on the shape: a quarter of the dataset finishes inside 5.7 hours, half inside 9.7, and three quarters inside 13.2 — so if your book runs past 13.2 hours, it's genuinely in the long quarter of everything we measured.

The extremes

The extremes: The Rook is the shortest at 0.5 hours, and The Complete Harry Potter Collection (Books 1-7) the longest at 101.8. Only 142 books (7%) cross the 20-hour line.
