Body Mass Tool for Children and Teens
The body mass index is a measure of a person's body fat. The index number uses a person's weight and height. It is used to find out if an adult is too thin, too heavy, or obese. In children and teens, the index is used to find out if a child is too thin, too heavy, or at risk of becoming too heavy. A child's body fat changes with age. Also, girls and boys differ in how much body fat they have as they grow.
This tool gives a fairly accurate BMI for children from age 5 to age 19. It will tell you if a child is underweight, at the right weight, at risk of being overweight, or is now overweight.
