For a 14 year old chick
Depends on the height. They say that for every inch taller you are you should be 5 pounds heavier. For example, if you are 5 feet tall a proper weight would be 100 pounds, if you are 5'1'' a proper weight is 105 and if you are 5'5'' a proper weight would be 125. Get it?
Depends how tall you are.
