The Body Mass Index (BMI) is a number that is designed to give you a quick idea of how healthy your weight is give your height.
It is not a perfect tool (please see the notes at the bottom of the calculator) but it is a good starting point. If you have any concerns about your current weight (either too fat or too thin), or if you have experienced unexplained weight loss or weight gain, please consult your doctor.
