Understanding BMI for Children
BMI for children is interpreted differently than for adults. It’s age and sex-specific because children’s body composition changes as they grow. The percentile indicates how your child’s BMI compares to other children of the same age and sex.
Disclaimer: This calculator provides an estimate of your child’s BMI percentile. It is not a diagnostic tool. Always consult a healthcare professional for assessment of your child’s growth and health.
