According to
this
article, in
Anime (and by proxy,
Manga) breast size is typically classified as follows:
| Term | Equivalent Cup size | Commonly Used For |
| | realistic | unrealistic | |
| Japanese | English | US | UK | Japan / EU | US | UK | Japan / EU | |
| Loli | "board flat" | no bra | no bra | no bra | no bra | no bra | no bra | Lolicon / Token Loli |
| Hinnyuu | small | AA to A | AA to A | AA to A | AA to A | AA to A | AA to A | Pettanko |
| Funyuu | average | B to D | B to D | B to D | B to E | B to DD | B to F | Ojou, Tsundere, Meido |
| Kyonyuu | large | DD to F | DD to E | E to G | F to K | E to H | G to L | Ms Fanservice, Femme Fatale, Hot Mom |
| Bakunyuu | very large | G to L | F to JJ | H to M | L to S | HH to M | M to T | Ecchi, Fetish, Hentai |
| Chounyuu | extremely large | M+ | K+ | N+ | T+ | MM+ | U+ | Ecchi, Fetish, Hentai (all up to eleven) |
Buxom Is Better usually runs from "Large" and above, with the divide between
Realistic and
Absurd types seemingly occurring between low-end and high-end
Very Large; mid-level Bakunyuu itself is pretty much
a grey area that can go either way. On the other hand,
Gag Boobs - by strict defintion - can
not go below mid-level-to-high-end
Average.
Notes:
- The last category is actually termed "impossibly large" in the original source, but since there are both natural and artificially induced real-life instances of this level, "impossible"/"impossibly" would be grossly misleading.
