NHS BMI calculator

Body Mass Index (BMI) uses your height and weight to tell you whether you are a healthy weight, underweight or overweight. Your BMI result is not the perfect measure of your overall health. It can't tell if you're carrying too much fat, doesn't take into account age, gender or musclar build.

You could use your BMI result as a starting point for further discussion about your weight, diet and general health with your GP.
