BMI Calculator

Body mass index (BMI) is a measure of body fat based on height and weight.


The result gives an indication of whether you’re a healthy weight, and if not, how over- or underweight you are. BMI isn’t perfect because there are other things that you need to take into account when it comes to weight, but it’s a useful guide.

Simply enter your details into our calculator and you’ll soon know if you’re a healthy weight for your height.
