Whilst height predictors can estimate a future adult height to a degree of accuracy, ultimately the rhythm in which children develop is determined by genetic and environmental factors, general health, nutrition and level of exercise during childhood, factors which cannot be completely accounted for in a model. Nutrition — a child with a nutritiously rich diet during childhood and adolescence will develop harmoniously;.
Hormone influence — with specific importance of the thyroid and growth hormones;. Exercise levels — children who practice sports tend to develop better than their non-exercising peers;.
A study by Silventoinen et al. One of the most commonly used is x-ray of left wrist, hand and fingers. The resulting image is compared to standardized images of bone development.
In children, growth is due to the growth plate areas of the bones, which are easy to identify on x-ray because of the different composition softer and with less minerals than standard bone.
Standardized growth charts are also used by pediatricians, for example the WHO charts for infants aged 0 to 2 years and the CDC charts for children above 2.
A child's height is controlled by the genetics but the genetic height is not an absolute. It gives us a range and the exact height of your child would depend upon many other factors like nutrition, stress and general health status.
There's no definite way to predict a child's adult height precisely. However, some formulas can provide an estimate for child growth. Here's a popular example:. Nevertheless, it can be interesting to try them out. Below the height prediction is some other interesting predictions relating to percentiles, weight lifting ability, and speed. Predicted Height Calculator Adult Height: The following additional analysis is for characteristics of an adult of the predicted height above.
Please note that the results are predictions for a statistical average and do not apply to anyone in particular. For more information, click on the various section titles. The simplest height calculator draws on the fact that children inherit genes from both parents. It takes the average height of the parents and add 2. Furthermore, it incorporates weight as this too is telling of growth to come. This is the method used by the height calculator at the beginning of this article. More advanced height calculators make use of bone age, which is a measure of age based on the size and shape of the bones as seen in radiographs, and formulas such as those found in the Tanner-Whitehouse method.
Another method is to calculate height percentile and then check that same height percentile for adults. While a height calculator may be useful, it is not intended for cases where an underlying height related disorder or syndrome may be present. Additionally, these methods have generally been developed for white American children and thus some prediction accuracy may be lost for other populations.

These growth charts consist of percentile curves illustrating the distribution of specific body measurements of children in the United States. In total, there are 16 charts that contain data that can be used to compare the growth of a child over time. Measurements such as height, weight, and head circumference of a child can be compared to the expected values based on data from these growth charts of children of the same age and sex.
In general, children maintain a fairly constant growth curve, which is why these charts can be used to predict the adult height of a child to a certain extent. There are also some very simple, but less accurate, methods available. One of them is adding 2. The second calculator above is based on this method. Another simple method is to double the height achieved by the child by age 2 for a boy, or age 18 months for a girl. As mentioned above, very tall parents are more likely to have a taller child, while very short parents are more likely to have a shorter child, with the child being more likely than their parents to be closer to average height.
After the growth spurt during puberty, which differs slightly for girls and boys, neither will typically grow much more, and girls typically stop growing by 15, while boys stop at around 18 years of age. That being said, there are environmental factors that can affect the height of a child. Some of these may be within the control of the child, while many may not.
