About BMI
Body Mass Index (BMI) is a measure of body fat based on height and weight. It is commonly used to categorize weight as underweight, normal weight, overweight, or obese.
For children and teens, BMI is age and gender-specific and is interpreted using percentile charts. This calculator adjusts for these factors.
