The classification of the height for babies and children up to 5 years is done according to the average values determined by the WHO. The entered height is classified according to age and gender in deviation ranges from the mean value. Three ranges of deviation are distinguished: σ, 2σ and 3σ. The following applies to the ranges:
In the ±σ range 68.27% of all children in this age group are
In the ±2σ range, 95.45% of all children in this age group are
In the ±3σ range, 99.73% of all children in this age group are
Body size up to 5 years
The diagram shows the course of body height for infants and toddlers up to the age of 5. The star in the diagram indicates the entered value. The colored areas indicate the σranges.

Body size measurement
Measuring the height of children
The easiest way to determine the height of children is to stand with their backs against a wall or door frame.
Both the heels and the back of the head rest against the wall.
A right-angled tool (e.g. large set square or book) is placed on the wall and pushed down until it touches the head. This can be used to make an accurate size mark on the wall.
The distance from the ground to the mark gives the body height.
Measuring the height of babies
Children under two years of age are best measured lying down.
It is helpful to have a second person available for support.
The child lies flat on its back, legs extended and head resting. The feet point upwards at right angles.
A tape measure is now used to measure from the bottom of the heel to the head.
