Audiobook Statistics

We track 580,000+ audiobooks on Audible across roughly 870 categories. The catalog spans fiction and non-fiction, with Literature & Fiction the single largest category at more than 225,000 titles. That scale is why standing out in a crowded genre is harder than producing the audiobook itself.

The median audiobook runs about 7 hours, and the 6-10 hour range is the most common length, covering roughly a third of the catalog. About a fifth of titles fall in the 3-6 hour band. Fiction tends to run longer than non-fiction - fantasy and historical fiction typically land near 9-10 hours.

Audible ratings skew high: the median overall rating is 4.5 out of 5, and about 55% of rated titles score 4.5 or above. Because so many titles rate well, a high score is the baseline to be competitive rather than a differentiator. Around 98% of active titles carry a rating.

Fiction is the most crowded. Literature & Fiction tags over 225,000 titles, and Romance, Mystery/Thriller & Suspense, and Science Fiction & Fantasy each exceed 95,000. Non-fiction lanes like self-development, business, and health are large but less saturated, which is where thinner supply can leave more room for a new title.

Audible rates story and narration (performance) separately. Across the catalog the median narration rating is 4.6 versus 4.5 for story, so performance tends to edge the writing. A strong narrator lifts the score a listener sees first, which is why casting is one of the highest-leverage decisions an audiobook maker controls.
