Body Mass Index (BMI) Calculator

Calculate Your Body Mass Index

What does your BMI say about your health? Are you within the healthy weight range? Use this BMI calculator to help you find out fast!

Rather than relying simply on the bathroom scale, experts are increasingly urging people to know their BMI, a figure that takes into account not just weight but height to indicate body fat. The goal for most people: a BMI that's over 18 and under 25.

A Few Things to Remember About BMI

Remember that your BMI is only one way of assessing your general health and risk for disease. A complete picture of your health risks depends on a variety of other factors, such as your family health history and your occupation.

Also, keep in mind that BMI does not measure your body composition - how much fat and muscle you have. So a person who has a lot of muscle, like a professional bodybuilder, may be "overweight" by BMI standards but not at risk for weight-related health problems.
