There is no actual ideal body weight calculation for an 11 year old like we have for adults. Using the adult calculation, you should weigh any where from 86-105 pounds. Where you stand in that calculation would depend on your body frame size (small, medium, or large). But again- THIS MAY NOT BE CORRECT - those numbers are based on a calculation for adults.
The best way to see where you are weight-wise, for your age, is to find your BMI (body mass index) by using the equation:
weight (in pounds) ÷ height (in inches)÷ height (in inches) x 703
so you would have your weight ÷59 ÷59 x 703
This will give you your BMI. Once you have your BMI you can look on a BMI chart for girls aged 2-20. Here is a link to one:
