Data story · romantasy definition by data
What is romantasy? We defined it with data — and measured 121 books
Instead of arguing about the label, we computed it: every book in our dataset carrying both romance and fantasy subject signals. 121 books qualify — and they look a lot more like fantasy than romance.
Our romantasy shelf is derived, not curated: a book qualifies when its subject data carries both romance and fantasy signals — a central love story plus fae courts, dragons, or magic. Across 2,000 audiobooks, 121 make the cut: 15% of all romance-tagged books and 14% of all fantasy-tagged ones.
Romantasy vs its parent genres
Length-wise, romantasy is fantasy wearing romance's cover: 13.1 hours on average — 46% longer than romance (9 hrs) and slightly above fantasy itself (12.3 hrs). It also out-rates both parents: 4.07★ vs 3.93★ for romance and 4.10★ for fantasy.
The practical read: picking up a romantasy means committing to fantasy-scale listening time. At 45 minutes a day, the average romantasy takes 18 days to finish versus 12 for the average romance.
