What is the most accurate height prediction method for children?
The one we provide here (the Khamis-Roche Formula) is proven to be the most accurate without the use of skeletal age. The most straightforward method ( Mid-Parental height formula) is based on parents height. The other conventional method of height prediction uses the roentgen radiation (which is potentially hazardous).
What is the Khamis-Roche method of height prediction?
It is valid for children above the age of four. This method of height prediction is known as the Khamis-Roche Method, and it was developed in 1994 at Wright State University in Dayton, Ohio. The publication by Dr. Harry Khamis and Dr. Alex Roche was called Predicting adult stature without using skeletal age: the Khamis-Roche method.
Can a growth chart predict the adult height of a child?
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.

How precise is this method? It's not, of course. The genetic potential height predictor has a 68% chance of being within 2 inches and a 95% chance of being within 4 inches of this predicted height. Another limitation is that you have to know how tall a child's birth parents are for this calculation to work.

The growth of bones is possible thanks to a particular area within two ends of long bones - the growth plate. This is a hyaline cartilage plate, which consists of actively growing cells. These plates can be found in children's bones, and, in adolescents, they turn into an epiphysial line (the residue of growth plate).
What is a standardized growth chart?

How is height determined?
The height of a person is determined by a combination of genetics and environmental factors. The precise contribution from these two factors is complex.
