Find your Body Mass Index
Body mass index (BMI) is a tool used to measure body fat. It is based on your height and weight. Your doctor may use your BMI to see if you are a healthy weight. The doctor takes your BMI number and compares it to the BMI numbers of other people your age. The comparison is called a percentile.
