How old is Ryne???? (Slight 5.2 Spoilers)

[Bhearil]

I always thought Ryne is about 11-12 because she's really tiny. She's Hyur and they are supposed to be of average height. But Ryne is way smaller than my female Au Ra who is almost at minimum height (147 cm). My Au Ra is tiny compared to Hyurs or real girls. Even I'm taller at about 152 cm. Back in school, I've always been the smallest in class, but even I wasn't like 135 cm at age 14, when I stopped growing.

What I wanted to say: I'm small and was a very small child, but Ryne is way smaller than me. How can she be about 14-16? If she were Elezen I'd say it's normal, but she is a Hyur girl.

Remember that on Japan girls of 1'70m are considered very tall and on many japanese works is not rare to see a decent ammount of female characters shorter than 1'50m specially if they are still on their growing phase
