if your a boy around 2,500 and if your a girl 2,000! Don't worry about your weight if that's what your worrying about..
The USDA estimates that boys ages 9 to 13 need 1,600 to 2,000 calories if they are sedentary, 1,800 to 2,200 calories if they are moderately active and 2,000 to 2,600 calories each day if they are active.
