What age would a youth x small fit?

age 10-12

I'm 20 and I fit size junior small but I have since I've been in middle school

i wear junior smalls and im 14

I am an 11 year old and I wear a medium but I am a little bigger for my age so I would say an 10 or 11 year old. Maybe even a 12 year old.

Should fit a size 12-14.
