BMI Calculator

BMI (Body Mass Index) is a measurement of body fat based on height and weight for men and women between the ages of 18 and 65.

A healthy BMI score is between 20 and 25. A score below 20 indicates that you may be underweight, while a value above 25 indicates that you may be overweight.

You can calculate your BMI by using our BMI Calculator below, or by using the BMI Formula.

Please remember that this is only one of many possible ways to assess your weight. If you are concerned about your weight, please discuss with your family physician or other health professional who can evaluate your personal situation.
