Height Predictor Calculator

Height is determined 70% by genetics and 30% by environmental factors like nutrition, health, and exercise.
There are many other variables, so the science of height prediction is not 100% accurate.
However, there are two methods that can give you a good estimate as listed below.
This app implements both the Mid-parent method and the more accurate Khamis-Roche method.
Tracking your childs height with this app can show you if your child is developing normally.

Mid-parent Method

This method can be used if your child is less than 4 years old.
Derived from a 1948 article by Horace Gray in the journal of Child Development, it is still widely used today.
The margin of error is +/- 4 inches or 10.16 cm.
This is a simple formula where the adult the adult height is calculated from the parents height and the childs gender.

Khamis-Roche Method

This method can be used for children 4 to 17 years old.
Developed by Dr.
Khamis and Dr.
Roche, this method is around 90% accurate.
It uses the childs age, gender, height, weight, parents height along with some scaling factors and equations to predict the childs adult height.

Bone-Age Method

The Bone-Age method is more accurate than the Kkamis-Roche method, but it requires that an X-ray of the hand.
Obviously, Adult Height Calculator cannot take X-rays! Maybe a future version of our smart phones can : ),
