BMI interpretation for children and adolescents differs significantly from adults because body composition changes rapidly during growth. Pediatric BMI is evaluated using age-and-sex-specific percentile charts from the CDC rather than fixed cutoff values. While this calculator provides the standard BMI formula, keep in mind that a child BMI of 22 means something very different at age 8 than at age 16. Consult your pediatrician for proper interpretation of your child results.

Body Mass Index (BMI) is calculated by dividing your weight in kilograms by the square of your height in meters (kg/m²). It provides a simple numeric measure of a person's thickness or thinness. While widely used by health organizations, BMI does not directly measure body fat percentage.
