BMI calculator

Healthy weight ranges are based on a measurement known as the body mass index (BMI). As it is difficult for any simple measurement to establish a person's frame, it’s more accurate to recommend a weight range for a person’s height rather than a specific weight.

If you know your weight and height why not work out your BMI with our calculator below? As weight is related to build, you should also make allowances if you are stocky or are of heavy build.
