Frequently Asked Questions

How accurate are child height predictors?

Mid-parental height predictions are accurate within 2-4 inches for most children. The method works best for children age 2+ and is more accurate at older ages. Genetics account for 60-80% of height, with nutrition, health, and environment affecting the rest.

What is the mid-parental height method?

For boys: add 5 inches to mother's height, average with father's height. For girls: subtract 5 inches from father's height, average with mother's height. This gives the genetic target height with a range of plus or minus 2-3 inches.

What is a normal growth percentile for children?

Any percentile from 5th to 95th can be normal. What matters most is that a child grows consistently along their own curve. Pediatricians monitor the pattern over time, not a single measurement.

Can I predict my child's adult height?

A rough estimate: average the parents' heights, then add 2.5 inches for boys or subtract 2.5 inches for girls. More accurate methods use current height, age, and bone age X-rays.
