ENTERING YOUR INFORMATION

The Body Mass Index Calculator can be used as a general gauge of how appropriate your body weight is for your height. By entering your current height and weight, you can assess if you are underweight, overweight, or just right.

The BMI Calculator is based on data taken from middle-aged men and women. It may not be accurate for pregnant or nursing women, competitive athletes, and the elderly. The normal ranges for BMI in children are entirely different, and vary according to age and gender.

More About This Tool

BMI stands for "body mass index," a numerical value of your weight in relation to your height. BMIs are good indicators of healthy weights for adult men and women, regardless of body frame size. Higher BMIs (30+) are associated with significantly increased health risks in some people. Could your weight be increasing your health risks? Use our BMI Calculator to find out.
