What is romantasy? We defined it with data and measured 275 books

Instead of arguing about the label, we computed it: every book in our dataset carrying both romance and fantasy subject signals. 275 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 8,560 audiobooks, 275 make the cut: 8% of all romance-tagged books and 13% of all fantasy-tagged ones.

Length-wise, romantasy is fantasy wearing romance's cover: 13.4 hours on average, 60% longer than romance (8.4 hrs) and slightly above fantasy itself (11.2 hrs). It also out-rates both parents: 4.08★ vs 3.90★ for romance and 4.05★ 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.
