BMI Calculator for Children

In kids, BMI is compared to growth charts by age and sex, not to adult "underweight" lines on the news. The tool plots a z-score and a text band, but growth spurts, sports muscle, and pediatric history matter more. Always confirm concerns with a pediatrician or a registered dietitian, not a single form field on a website, before changing diet or activity.
