How can I determine the BMI value

BMI calculator: determine your body mass index quickly and free of charge

Correctly assessing your own weight is not always easy. Our BMI calculator provides the first clues as to whether you should really lose weight. It is based on the classification of the World Health Organization (WHO).

Body Mass Index (BMI) = 24

You should definitely do something about your excess weight. Talk to your GP and pharmacist how you can best do this.

What is the BMI?

The body mass index - BMI for short - is a parameter that helps determine whether weight and height are medically healthy or whether the person is, for example, very overweight, i.e. obese. The World Health Organization (WHO) divides the BMI into six different classes:

Under 18.5: underweight

18.5 - 24.9: normal weight

25 - 29.9: overweight / pre-obese

30 - 34.9: Obesity (obesity) grade I.

35 - 39.9: Obesity grade II

Over 40: Obesity grade III

The individual weight to be aimed for also depends on age, gender and other information. Your doctor will help you determine the right weight for you.

What formula is used to calculate the BMI?

The BMI is calculated using the following formula:

Body weight (in kilograms) divided by height (in meters) squared.

A calculation example should make this formula even clearer: Imagine you are 1.70 meters tall and 80 kilograms.

Then do the math: 1.70 x 1.70 = 2.89

Now divide your weight by this value: 80: 2.89 = 27.7

27.7 - or rounded up to 28 - is your body mass index (BMI).

What is the meaning of the BMI?

The body mass index only allows a rough estimate. For example, if you have a lot of muscle mass, you can have a high BMI without being overweight in the true sense of the word. The BMI also says nothing about the distribution of body fat. In particular, too much belly fat is considered a health risk. There are other classifications that include age and gender in the assessment. For example, with increasing age, the metabolism and body composition change.

As a result, many experts now consider the value "waist circumference in centimeters divided by height in centimeters" (English: Waist-to-Height-Ratio, abbreviated WHtR) to be more meaningful. A value below 0.5 (below 0.6 for older people) is desirable here. The waist circumference alone also helps for a rough orientation: it should not be more than 102 centimeters for men, and not more than 88 centimeters for women.

Does the BMI calculator also apply to children?

There are separate rules for children. There are special BMI tables here and the BMI can only be viewed as a guide, as they are still growing. A BMI calculator for children can be found here. If you have the feeling that your child weighs too much or too little, it is best to talk to your pediatrician about it. In no case do not just put the child on a diet.

Is the crisis an opportunity?

Many people fear that they will gain weight during the corona pandemic - because they move less in the home office and the refrigerator is just around the corner, or because stress and fears lead to frustration. The good news: The exceptional situation can even help you leave unhealthy routines behind, i.e. eat more consciously.
