Every body is different so never base it on someone's calculations. If you are very active consume more calories, but if your not very active consume less. I am a very active 13 year old girl and am supposed to eat at least 2500 calories a day and right now I am under weight. I am 5'8 and weigh 121 which is underweight and I lose weight if I eat less than 2500 calories. Now, your body may be different which is my point. It depends on your height, activity and all around genes.
The average 13 year old's weight is about 105-135 lbs.
The average weight for a 13 year old girl that is 5 foot tall is between 90lbs to 100lbs.
