Body Mass Index Calculator (BMI)

Body mass index (BMI) has been the medical standard for obesity measurement since the early 1980s. Government researchers developed it to take height into account in weight measurement. For example, let's say someone weighs 150 pounds. Is he or she obese? That's impossible to say without knowing the person's height. The answers would be different for someone who is 5' 0" tall, 5" 4", and 5' 11".

To calculate your BMI, enter your height in feet and inches, and your weight in pounds in the boxes below, then click on the button marked "Compute."

ft  in lbs

Recommended BMIs are in the range of 20 to 24.9.

The "overweight" range is 25 to 30.

The "obesity" level is anyone with a BMI over 30.

According to these conventions, the woman who is 5' 0" and weighs 155 has a BMI of 30.14, and is obese.

Someone who is 5' 4" and weighs 155 has a BMI of 26.6, and is overweight, but not obese.

Someone who is 5' 11" and weighs 155 is in the healthy BMI range.
