What’s your Body Mass Index (BMI)?*

Your Body Mass Index (BMI) is a number calculated from your weight and height. It’s not a precise calculation of percentage of body fat, but it is an easy way to determine where your weight falls in the range from healthy to unhealthy.

You can use your BMI as a starting point for talking with your doctor about your weight, health and treatment options.

It is important to note that BMI is a useful measurement for most people over 18 years old. But it is only an estimate as it doesn’t take into account age, ethnicity, gender and body composition.
