Based on bone age, doctors will know how long a child’s development will last, at what age children begin puberty and what their future height will be. This study is also used to measure any growth deficiency that may be caused by various factors which can be hormonal, orthopedic and genetic in nature. The bone age method is quite accurate because it requires X-rays to predict a child’s future height. (first)

The percentage curves show different details of the upper body parts of the child. There can be many charts comparing different growth rates of those body parts. We can take into account a variety of measurements such as a child’s height, weight, and even head circumference.
