What is the average weight for an 11 year old Who is 5ft 4 tall but weigh's 111 lbs is she over weight?

I would say 11 is pretty young to be 111 pounds, but since you are taller than normal 11 year olds, it all evens out. You don't have to be worried, you are not overweight at all. Based on the numbers, and your height, your weight is normal. But I don't base it on numbers, I just look in the mirror. I don't worry about it much, of course I still excersise and eat healthy (a binge here and there!:) but I don't let it overtake me. You are fine!!!
