BMI Calculator

This body mass index (BMI) calculator is based on a simple ratio between your height and weight. Some people may have heavier skeletal structures or very large muscle mass and will need to take a different BMI test (like one that uses water displacement to determine actual fat mass).

Enter your height in feet and inches and your current weight, then compare your results with the table below.
