Your Body Mass Index, or BMI, provides a simple numeric measure
of your "fatness" or "thinness".
BMI is based on your weight to height ratio and our free BMI calculator below
uses the internationally recognised formula to calculate your BMI index.
Use our free Body Mass Index calculator (BMI) to find your body mass index. Simply enter your height and weight, click "Calculate BMI" and then see where you are on the WHO scale on the right.
