BMI Calculation

Calculate your Body Mass Index (BMI).

About the "BMI Calculation" Calculator

The Body Mass Index (BMI) is a simple and recognized tool to assess your body size and quickly identify potential health risks. It relates two simple data points: your weight and your height. In a few seconds, our calculator gives you a number, but what does it really mean?

BMI helps you place yourself in weight categories defined by the World Health Organization (WHO). It is an essential first step to become aware of your weight status. However, be aware that BMI has its limits: it does not distinguish between muscle mass and fat mass and is not always relevant for high-level athletes or pregnant women. It should be considered an indicator, not a diagnosis.

How to interpret your result?

  • Less than 18.5: Underweight. It may be wise to consult a doctor.
  • Between 18.5 and 24.9: Normal weight. You are in the right zone!
  • Between 25 and 29.9: Overweight. It might be time to review some habits.
  • 30 and over: Obesity. Medical follow-up is strongly recommended.

For example, a person measuring 1.75 m and weighing 70 kg has a BMI of 22.9, which is considered normal. Use this tool as an ally for your well-being, and do not hesitate to discuss the results with a healthcare professional.
