A 30-year-old member asked:

what is the rule for predicting height of a child based on parents?

None: Typically a child's adult height will be somewhere between those of his parents.
Dr. James Ferguson
Pediatrics 46 years experience
Average +/-: The common rule we start with averages the height of the parents and adds 2.5 inches if a boy and subtracts 2.5 inches if a girl. This gives a rough figure with many possible exceptions. The best predictor becomes the pattern of growth the kid exhibits during childhood and the age s/he starts into puberty.(growth charts on their docs records)

A 44-year-old member asked:

Can two short parents have an average height child?

1 doctor answer6 doctors weighed in
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.

Child height predictor based on parents and grandparents?

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.
