BMI Calculator

To determine if you're at a healthy weight, enter the following information and calculate your BMI (body mass index).

Weight: lbs.
Height: ft. in.
 

Body Mass Index or BMI is a ratio calculated from your height and weight. BMI is recognized by the National Institutes of Health (NIH) and The World Health Organization as the best standard to determine obesity and associated health risk.

Health care professionals frequently use BMI to determine if a person is at a healthy weight or is overweight or obese. While BMI is accurate for most people, it doesn't work for all individuals. For example, BMI can:

  •   Incorrectly estimate health risks of people with excess abdominal fat
  •   Overestimate body fat for people who are muscular or athletic
