Calculate your BMI


This calculator computes the body mass index and rates it appropriately for men, women, children, juveniles and seniors. The SBMI – an index that has been developed four years ago especially for this calculator – serves for this purpose. It is based on the results of the most comprehensive study* published so far on the BMI and its associated health risks.

The values entered here will only be stored in the results page of your browser and nowhere else. Your privacy is guaranteed.
