BMI Calculator

Calculate your body mass index using your height and weight. This tool can help you see your BMI category and estimated healthy weight range.

This calculator is for adults only. It is not suitable for children, teenagers or pregnancy.

What BMI means

BMI stands for body mass index. It uses your height and weight to estimate whether your weight is in a lower, healthy, higher or obesity range for most adults.

Useful, but not perfect

BMI does not measure body fat directly. It may be less useful for some people, including those with high muscle mass.

When to get help

If your weight changes unexpectedly, your BMI is very high or low, or you are worried about your health, speak to a qualified clinician.
