How tall is the average thirteen year old?

Well for a girl 5'4-5'7 for a boy since they are usually shorter than girls around 11-13 years old about 5'3 to 5'6 I'm a 12 year old girl and I'm 5'6 but that's the height of an average 13-14 year old girl. But boys especially around 11 are usually shorter than the girls.
