What is my BMI?
Do I have ideal weight, obesity or possibly obesity ? Or am I even too thin? Whether you have normal weight, you can read the so-called body mass index (BMI). In the BMI calculator you only need to enter your height and body weight. The rest is done by the BMI calculator for you. You can enter your data in the fields below. Then click on “calculate BMI” and your personal BMI will be calculated.
BMI calculator – for the formula of weight and height
The Body Mass Index (BMI) describes the ratio of body weight to height. The BMI calculator determines the BMI from the weight divided by the size squared. An example: You are 1.70 meters tall and weighs 75 kilograms. Your body mass index is calculated in the BMI calculator: 75 / 1,702 = 25.9. For a quick overview, see the BMI chart below: Find your BMI at the intersection of height and weight.
weight in kg
|Height in cm|
|from 30 = clear overweight|
|25 – 29.9 = overweight|
|19 – 24.9 = normal weight|
|under 19 = underweight|

|BMI female||BMI male|
|underweight||under 19||under 20|
|strong obesity||greater than 40||greater than 40|
The BMI by age
The optimal BMI depends on additional factors such as age. A slight increase in body fat is absolutely normal with age. Muscles need more energy than fat cells, but with less muscle as they get older, calorie consumption decreases compared to younger people. Keeping eating habits with age leads to weight gain. As you grow older, your height will also decrease.
The optimal BMI by age:
|19 to 24||19 to 24|
|25 to 34||20 to 25|
|35 to 44||21 to 26|
|45 to 54||22 to 27|
|55 to 64||23 to 28|
|65+||24 to 29|
Calculate BMI: How dangerous is a high BMI?
High weight alone does not necessarily mean that there is a risk to your health. The BMI also gives only a rough indication, but with a BMI of 30 and above, the risk of health consequences is generally considered elevated.
The BMI calculator can deliver wrong values for very tall and very small people. Likewise with very muscular people – because muscle mass is heavy, it weighs more than fat. Accordingly, for example, athletes have a high BMI – but are fit, pay attention to a healthy diet and often even have their ideal weight. Therefore, the body mass index should always be considered together with the waist circumference.
The waist circumference of the BMI formula
Health risky is namely in every gender, the fat in and on the stomach. The risk is increased if the waist circumference is over 88 centimeters for women, and for men over 102 centimeters. The problem: Excessive kilos in the middle of the body affect the metabolism negatively. The consequences are, for example, higher blood sugar levels and higher blood pressure.
Am I overweight? This formula also reveals it!
In order to better assess whether you are underweight, normal weight or overweight, in addition to the BMI calculator occasionally also the formula WHtR (waist-to-height ratio) is used. Unlike the BMI table, it should give much better information about our disease risk than the BMI (body mass index) based on waist circumference and height. More about WHtR .
The BMI as hype?
Originally, the BMI calculator was not intended to provide ideal body weight values. The inventor of the BMI, Iganz Kaup, actually used the table for research in social statistics. And even the predecessor of the system, the so-called quetelet index after Adolphe Quetelet should only provide statistical measures for the relation between weight and size. It was never a question of whether someone can use it to calculate his BMI and find out whether he has normal weight, underweight, obesity or even obesity.
Accordingly, you should not immediately put on a diet, if your value at the BMI calculator does not meet your ideals or slightly deviates from the predetermined normal range. First, consult with your doctor and reflect your dietary habits. If it is necessary from a health point of view to treat your weight, your doctor will go through the best methods with you.
