How is BMI calculated ?

Body mass index is calculated by dividing weight (in kg) by height squared (in metres) : BMI = weight / height². According to the WHO, a BMI between 18.5 and 25 is considered “normal”.

Frequently asked questions

Is BMI reliable ?

It is a general indicator that takes into account neither muscle mass nor fat distribution. It shows a trend, not a diagnosis. If in doubt, consult a healthcare professional.
