Is a 130 pound 14 year old girl over weight?

Depending on the Height and bone structure of the 14 year old, this could be a normal weight for her size. Also keep in mind that at the beginning of puberty, we tend to gain that extra baby fat and burn it off normally by our later teens. If she is anywhere between 5 ft 3 and 5ft 9, I would say she is nice and healthy.
