The content of this site offers parents the possibility to enter their child's measurements and obtain height and weight growth charts plotted against the WHO references. Such information is not intended as medical advice and is not a substitute for the advice of a health care professional. Only a licensed healthcare provider can diagnose growth problems. If you have or suspect having any growth problems, print out the pdf chart and discuss it with your health care professional at the next office visit. The data you are entering will only be saved on your local computer and are never stored or accessible by Novo Nordisk or any third party.
Standard Deviation (SD) and Standard Deviation Score (SDS)
A Standard Deviation Score (SDS) indicates how many Standard Deviations (SD) a measurement (e.g. height) is above or below the mean value in e.g. a specific age group. Here are some examples: If a 10-year old girl has a Height SDS equal to 0, it means that she is average, her height is the same as the mean height for 10-year-old girls. If a 10-year old girl has a Height SDS equal to -1, it means that she is below average, if it is +1 she is above average. An SDS between -2 and 2 is considered normal; if your child is growing normally, your child's SDS value for height should fall somewhere within this range.
Child's target height
This figure shows how tall your child is expected to be, on average, when growth is completed, based on the parents' heights (i.e. genetic potential for growth). This is called the child's target midparental height. Taller parents tend to have taller children.
Commonly used formula for calculation of target midparental height is:
- Height of the father in cm plus the height of the mother in cm.
- Divide that number by 2.
- Add 6.5 cm for boys and subtract 6.5 cm for girls.
If the adult height of one or both parents is not known, then the target midparental height cannot be determined.
Proper measuring technique
If you're measuring your child's height at home, it is very important to do the measurement in the same way every time and, ideally, at the same time of day.
You'll get the best and most consistent results by following these steps:
- Attach a measuring tape to a flat surface like a wall or a door. The floor should be a hard surface and not carpeted.
- Remove your child's shoes.
- Have your child stand against the flat surface (i.e. a wall or door) with heels, buttocks, shoulders and back of the head touching the wall or door. The feet including heels should be flat on the floor.
- Lower a book or other right-angle object until it touches the head, and mark the height on the wall or door.
- Read the height on the measuring tape where the lower edge of the triangle rests.
- Enter the measurement and measurement date into the entry fields.
Please note: The above method should be used to measure height after age 2. The method used to measure height during the first 2 years of life differs from the method used to measure height after age 2.

Normal Range
The data used to derive these charts come from the World Health Organisation (WHO) child growth standards 2006 / 2007. Please note that WHO growth charts are not population/nation-specific; health care professionals can help with your child's growth assessment using appropriate nation-specific growth charts.
Height data are available between birth and 19 years of age.
Weight data are available between birth and 10 years of age.
