BMI Calculator
Body mass index (BMI) is a measurement based on height and weight as it relates to body fat, and can be used to determine how much risk a person has of developing certain health problems because of his or her weight. As a point of reference, someone with a BMI of 27 is approximately 20 percent overweight. The higher the BMI, the greater the risk a person has to develop additional health problems.

To determine your BMI, simply select your height and type in your weight where specified in the form below. The calculator will automatically calculate your BMI score.

On the BMI graph above, find your score and the health risk for which it is assessed. For example, a BMI score of 20 - 25 is associated with the lowest health risk based solely on BMI scores. If your score is over 27, you are considered to be at increased risk for health problems that are negatively impacted by obesity, such as diabetes, heart disease, high cholesterol or hypertension. Exceptions to a high BMI score include competitive athletes and body builders, whose BMI is high due to increased muscle mass, and women who are pregnant or lactating. The BMI is also not intended for use in measuring growing children or elderly individuals.
