Calculate your BMI


An international standard has been adopted to measure excess weight and obesity. It is the Body Mass Index (BMI), defined as the weight divided by the square of the height, expressed in kg/m². Discover how to calculate your BMI using our tool.

The BMI estimates the degree of obesity and evaluates the associated risks to health (comorbidity). A person is considered obese when this value is greater than or equal to 30 kg/m².

The result of your BMI determines your health in terms of weight. If your BMI is:

  • Less than 18.5 : underweight
  • Between 18.5 and 24.9: “normal” weight
  • Between 25 and 29.9: overweight – the person needs to lose weight and has a high chance of developing health problems
  • Between 30 and 34.9: moderate obesity, the risks are even greater
  • Between 35 and 39.9: severe obesity
  • Greater than 40: massive or morbid obesity
