Body Mass Index (BMI) for children is different from adults. Because children are growing, their BMI is plotted on age- and gender-specific percentile charts to see how their measurements compare to other children of the same age and gender. This calculator allows you to find your child's BMI and their corresponding percentile, which is a key screening tool used by pediatricians to assess a child's growth.
