Is 5'7 a normal height for a 13 year old?
I'm 15 and almost 5'8 which is just around average height for a girl to finish at so 5'7 is only just over normal for a 13 year old.
Your tall I'm 5'7 a guy and 17 idk average
That is a completely normal height.
Girls mature faster then boys so yes, it is normal.
Look at your female classmates and make a wild guess.
