The calculator calculates the BMI and arranges the results accordingly to age and gender according to the BMI tables for children, adolescents and adults and displays the result graphically.

The diagram shows the calculated BMI value as a star in the weight-size diagram with the colored classification ranges. The diagram is calculated according to age and gender.

BMI in Weight Size ChartThe diagram shows the calculated BMI value as a star in the age-dependent diagram with the colored classification ranges. For adults aged 19 or over, the star is displayed on the right, as the BMI values from 19 years are constant. This chart is of interest to children and adolescents under the age of 19 because it is the age-dependent course of the BMI limit values. The diagram is generated according to gender.

BMI in Age ChartThe Body Mass Index (BMI) is a measure that sets the weight in the ratio to the square of the body weights. The BMI is a rough guide, since it does not take into account either stature or weight distribution. Since the beginning of the 1980s, the BMI has also been used by the World Health Organization. The present BMI classification of the WHO has essentially existed since 1995.

BMI = m / L^{2}

with m : Weight in kg, L : Height in m

The interpretation of the calculated BMI value is based on the comparison with the tabulated average values of the population. That is, the normal range (green in the diagrams) corresponds to the average in the population at the time of the survey.

The Body Mass Index (BMI) is a measure for the assessment of the body weight of a person in relation to its body size.

The BMI is only a rough guideline as it does not take into account the stature and sex or the individual composition of the body mass from fat and muscle tissue of a human being.

Age and gender play an important role in the interpretation of BMI. Men generally have a higher proportion of muscle mass in total body mass than women. The BMI can also be used in children and small children as a measure for the healthy development of the child. However, the BMI is interpreted by adults according to the same formula as the BMI for childs but is interpreted according to age.

The limits of an appropriate BMI are strongly related to the development of the child. For example, the rapid growth of the length in the initial phase of puberty and the like is depicted. If a child develops these developmental phases sooner or later than the average, a BMI that is too high or too low, depending on the age group, can be present.
