How tall you will be

The accuracy of the multiplier method was compared with the CDC growth charts a preferred method when available using longitudinal growth data from 52 normal children. No significant differences were noted between predictions made using the CDC growth charts versus the multiplier method meaning our tool is a highly accurate height calculator for teenagers and childern alike.

The future prediction method was also compared to other growth databases from around the world and from different eras and the height multipliers were shown to be independent of height percentile, race, and generation, indicating that the multiplier method is universal.

The accuracy of the method used in this height predictor is comparable with that of the Bayley-Pinneau [2] , RWT [3] , and TW3 [4] methods. The last part is especially relevant in the U. As with any other statistical method applied to an individual the one used in our adult height predictor is prone to some error. Absolute error of prediction AEP is defined as the magnitude of either overprediction or underprediction of height.

For boys , the median AEP using the multiplier method ranges from 1. For girls , the median absolute error of height prediction calculation using the multiplier method ranges from 0. We recommend that the adult height calculator is used only for children without pathologic conditions that alter the potential for growth in stature and to always consult a pediatrician when making health-related decisions.

A number of methods for height prediction relying on examinations of skeletal structure are often used by pediatricians, for example the Bayley-Pinneau [2] , the Roche-Wainer-Thissen RWT [3] and the Tanner-Whitehouse 3 method [4].

However, all these methods are subject to a wide range of error , at least partly because of the use of bone age estimations. Determination of skeletal age is relatively subjective , with a high interobserver error rate, and the relationship of skeletal age to chronologic age has been shown to differ among various ethnic groups [1].

The period of the first few years of your life is also important - how did you eat, how did you sleep, did you suffer from any disease? Our height is also dependent on the country of our origin. For example, men born in Japan in achieved an average height of Men born in Belgium achieved a height of It is well known that theoretically, we are growing both ways.

Can you guess what's the matter? In addition to height, our weight also grows. Do you think we'll also be able to guess if you're too fat?

You already know everything about what depends mainly on our height. By inheriting genes from both parents, a child usually grows to their average height. However, the activity of genes can vary, and so too can growth. And beyond genes, there are environmental factors like wellness, activity, and nutrition. 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. Based on bone age, the height of the child, and the data compiled in the atlas, it is possible to predict height based on the percentage of height growth remaining at a given bone age.

Note that the data in the atlas were obtained between and from Caucasian children, which may limit how accurately the Greulich-Pyle method can be used for current children. The Khamis-Roche method is considered to be one of the more accurate height prediction methods that do not require the measurement of bone age.

It is based on the child's stature, weight, and the average stature of the two parents. The first calculator above is mainly based on this method. Note that it is most applicable to Caucasian children between the ages of 4 and 9 who are free from any growth-related condition or disease.

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.
