Average the parents' heights, then add 6.5 cm for a boy or subtract 6.5 cm for a girl (13 cm is the average male-female difference). About 95% of children end up within 8.5 cm of that figure.
Methods that add the child's current height, age and bone age (such as Khamis-Roche or a bone-age X-ray) are more precise. A pediatrician can assess growth concerns.
