BMI Calculator Childs

BMI calculator to calculate the Body Mass Index (BMI) for boys and girls in age of 1 to 5 years

The BMI calculator calculates the BMI and ranks the result according to age and sex according to the BMI tables to a week for childs and displays the result graphically.

The red line shows the calculated BMI and below the ranges the limit value for the BMI and the corresponding limit weight is shown.

BMI in weight-size diagram

The diagram shows the calculated BMI value as a star in the weight-size diagram. The colored classification areas show the BMI ranges depending on the height and weight of the child. The diagram is calculated according to age and gender and shows the course of the BMI limits.

BMI in Age diagram

The diagram shows the calculated BMI value as a star in the age-dependent diagram with the colored classification areas. The diagram shows the course of the BMI limits for childs in age of 1 to 5 years. The diagram is created gender dependent for boys and girls.

BMI Calculation

The 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 / L2

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.

Explanation of the BMI

The Body Mass Index (BMI) is a measure of a person's body weight in relation to their height. The BMI is only a rough guide value, as it does not take into account a person's stature or the individual composition of body mass from fat and muscle tissue. Age and gender play an important role in the interpretation of the BMI. In children and infants, the BMI can be used as a rough guideline for the healthy development of the child. The BMI is calculated using the same formula as the BMI of adults, but is interpreted according to age. The limits of an appropriate BMI are strongly related to the child's developmental stage. If a child goes through a developmental phase sooner or later than average, a BMI that is too high or too low according to the age group may be present despite normal weight.
