She isn't that old physically but her figure is rather developed. She's also a mature character so I think late-teens. Not too young, not too old. Does Belle have an offical age or is it not confirmed? Though if she DOES have an offical age I think it'll be 16 because most of the princesses are 16 and for some reason Disney LOVES making the princesses at least 16 years old.

definitely 18 or 19

21. Alcohol is served during be our guest, and I doubt disney would advertise drinking under 21. (since that is the legal age in the U.S., where the movie was made) and The Beast is 21, and Id say they are around the same age. Plus, she doesnt seem like a teenager to me.

I'm thinking 19

or 18, maybe 19

i've always thought she was 19

or 18

She's young but not as young as Ariel.
