BMI Calculator

You can use the Body Mass Index (BMI) to work out if you are underweight, overweight or at an ideal weight for your height. It is a useful tool, but keep in mind that it can be influenced by gender, age and ethnicity, so use it as a guide only.

This calculator can be used for anyone aged 19 years and above.

If you are aged 18 years or younger, you can use a children and teenager calculator to find out whether you are a healthy weight.

The Get Healthy Information and Coaching Service can help you reach your own healthy weight goal.
