BMI calculator

Body mass index (BMI) and waist circumference are measurements that can show if you are a healthy weight for your height.

These measurements can be used to get an idea of your chance of developing some health conditions including diabetes, high blood pressure, and other metabolic conditions.

BMI isn't always the best way to work out if you are a healthy weight because it can't tell how much muscle or fat you have. It is also less accurate for assessing healthy weight in some groups of people.

Waist circumference is a good indicator of 'hidden fat' around organs in our bellies. It may be a better guide than BMI alone in estimating risk for the same types of health conditions.
