The Body Mass Index, or BMI, is a measurement used to compare a person’s weight and height. Although it doesn’t actually tell you what percentage of your weight is body fat, it can be useful to estimate a healthy body weight based on your height.

The BMI is widely used as a diagnostic tool to identify the statistical degree of obesity in individuals and groups. Use the chart to the right of the calculator as a quick visual check of where your body mass level falls – the normal, healthy range is indicated in yellow.

To use our BMI Calculator, simply enter your height in feet and inches, and your body weight in pounds. Or you can use the metric units tab if you are more familiar with international metric units.
