Weight Loss Basics

BMI Calculator for Children and Teens

Body Mass Index (BMI) is a person's weight in kilograms divided by the square of height in meters. A high BMI can be an indicator of high body fatness. 

BMI can be used to screen for weight categories that may lead to health problems but it is not diagnostic of the body fatness or health of an individual. Calculate BMI using the widget below.
