TALL STATURE: You can predict the child to be tall if parents, grandparents and other relatives are tall. The percentile will also show the development as the child grows.
Dr. James Ferguson
Pediatrics 46 years experience
Simple measures: Expected height from parent stature is equal to the average parent height (m+d/2) + 2.5 inches for males, -2.5 in for girls.Grandparent height is not used but may point to variations in accuracy of the method. This is only a basic predicted height. Some very tall or very short people come from normal sized parents, & a life's medical & nutritional issues can slow the growth of anyone.

A 44-year-old member asked:

Can two short parents have an average height child?

Dr. James Ferguson
Pediatrics 46 years experience
Possible: The expected height of kids would be average parental height + 2.5 inch for boys and -2.5in for girls. If either or both parents have genetic material on board from their families that should have made them taller, there is some chance that a taller child could be produced. Often the eventual stature of kids can be predicted in mid childhood using their bone maturity and pattern of growth.
