BMI Calculator

BMI, or Body Mass Index, is the most common "fatness" index used today. It is based on your weight and your height only - so someone who is a body-builder who is extremely muscular may have a high calculated BMI even though they do not have much body fat. For most of us, however, it is a good simple calculation to let us know where we stand.  A BMI below 25 is considered "normal weight" (below 17 is underweight), a BMI of 25 to 30 is "overweight", and a BMI over 30 is considered "obese".  Many people with a BMI of 25 or 26 do not appear to be overweight - this scale is aggressive at identifying people as overweight.

The calculator below will tell you your BMI and plot it on a graph - you cannot change your height, but you can get an estimate of what weight you would need to reach to reduce your BMI to a better number. (And you can repeat the calculation with various weights).
