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 healthy BMI for a toddler?

For children ages 2-5, a healthy BMI-for-age falls between the 5th and 85th percentile on CDC growth charts. Unlike adults, children's healthy BMI ranges vary by age and gender because body composition changes as they grow. A pediatrician can best assess your child's growth.

How is toddler BMI different from adult BMI?

While the BMI formula is the same, interpretation differs. Children's BMI is plotted on age- and gender-specific growth charts as percentiles, not fixed categories. A toddler's BMI naturally changes as they grow, so percentile tracking over time is more meaningful than a single reading.
