How tall will I be?

The height of a person is determined by a combination of genetics (60-80%) and environmental factors. A child's height is based on parental heights subject to regression toward the mean — very tall or short parents are likely to have children closer to average height.

Other important factors include nutrition, health, sports activities, and the health and age of the mother during pregnancy.

Methods for Predicting Height

Bone Age (Greulich-Pyle): Uses left hand and wrist radiographs to measure bone age. Considered more accurate but requires medical imaging.

Khamis-Roche Method: Uses child's stature, weight, and average parent height. Most applicable to Caucasian children ages 4-9.

Growth Charts: CDC growth charts compare a child's measurements to population percentiles to track growth curves.

Simple Method: Add 5 inches for boys or subtract 5 inches for girls from the average of parents' heights.
