BMI Calculator

Body Mass Index is measured differently for children and adults. If you are 19 or younger use this BMI calculator for children and adolescents to find out about your BMI and what the number can tell you. If you are an adult, try our calculator and read below.

For overweight or obese adults with other health problems, national guidelines recommend weight loss. Even a small weight loss (just 10 percent of your current weight) will help to lower your risk of developing diseases associated with obesity such as high blood pressure, high blood cholesterol, type 2 diabetes, heart disease, stroke, and certain cancers. Talk to your doctor if you are concerned about you or your child's Body Mass Index.
