Child's Estimated Adult Height Calculator
Tools by Health Topic A-Z
Body mass index (BMI) is a measure of a person's body fat. BMI is calculated using a person's weight and height. BMI is the most commonly used method to determine if an adult is overweight or obese. In children and teens, BMI is used to find out if a child is underweight, overweight, or at risk of becoming overweight. A child's body fat changes with age. Also, girls and boys differ in their amount of body fat as they mature. This is why BMI for children, also known as BMI-for-age, includes gender and age.
This calculator gives an approximate BMI for children from age 5 to 18. It will tell you if a child is underweight, at an ideal weight, at risk of being overweight, or is now overweight.
