BMI Calculator

Your body mass index, or BMI, is used to determine whether you are in a healthy weight range for your height. It is useful to consider BMI alongside waist circumference, as waist measurement helps to assess risk by measuring the amount of fat carried around your middle.


BMI is a useful measurement for most people over 18 years old. But it is only an estimate and it doesn’t take into account age, ethnicity, gender and body composition. We recommend you also check your waist measurement and other risk factors.


Do you know your BMI? This calculator shouldn’t be used for pregnant women or children.

Calculate Your BMI

Your BMR calculator generates the number of calories your body burns per day at rest. Your BMR with activity factor is the number of calories your body burns per day based on the activity factor you selected.
