Check your child's BMI against CDC and IAP percentile bands, with India-specific notes for parents of children aged 2 to 18.

Calculator

Check your child's BMI

Uses CDC age-and-sex BMI-for-age percentile charts (ages 2-18), cross-referenced with Indian Academy of Pediatrics (IAP) 2015 guidance. Indian children can carry more body fat at the same BMI as Western children, so treat borderline numbers as a conversation starter with your pediatrician.

Between 2 and 18 years.

India-specific note

Indian children often store more central body fat at the same BMI than peers in the CDC reference data. The Indian Academy of Pediatrics recommends treating a BMI at the 85th percentile as a watch point and the 95th as a referral point. If the result feels off compared with what your pediatrician sees, ask about waist circumference and IAP-specific charts.

For screening only. A single BMI reading does not diagnose anything. Discuss the trend with a pediatrician, especially for very tall, very short, very muscular, or chronically ill children, where BMI is less reliable.
