BMI Calculator

Calculate your body mass index or BMI with this BMI calculator.

According the National Institutes of Health, for adults age 20 and over:



BMI under 18.5 = Underweight

BMI of 18.5 to 24.9 = Healthy

BMI of 25 to 29.9 = Overweight

BMI of 30 to 39.9 = Obese

BMI over 40 = Morbidly Obese

These are not my definitions. If you don’t like the labels, take it up with the NIH.
