What is the average height and weight of a 12-13-year-old-girl?

The average weight of a 12-13 year-old girl is about 95 pounds. And the average height is around 4' 6". But it all depends on your parents genes and the traits you got from them, so don't feel bad if you're shorter, taller, less weight, or maybe more. It mainly depends on your traits and how much muscle you have. And just remember that muscle weighs more than fat.
