Calculate your BMI

Questionnaire

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.
