BMI Calculator

Your BMI is


A healthy BMI for adults is between 19 and 26. A BMI of 27 to 30 is considered overweight. Obesity is classified as a BMI of 30 or above.

If your BMI is below 19, you may be at risk for problems such as osteoporosis. A low BMI may also be a sign that you are ill. If your BMI is in the overweight or obese range, you are at greater than average risk for conditions such as coronary heart disease, type 2 diabetes, and high blood pressure.

Result notes
BMI values apply to adult men and women, regardless of their frame size or muscle mass — with the following exceptions: competitive athletes, body builders, pregnant or nursing women, and frail or sedentary elderly people.

If you think your BMI results do not accurately reflect your body fat level, tell your doctor about your results and ask for a body fat test.
