Frequently Asked Questions
How accurate are height predictions for toddlers?
The mid-parent method is accurate within about ±2 inches (5 cm) for most children. The 'doubling method' (doubling height at age 2) is a rough estimate. Genetics plays a major role, but nutrition, health, and activity also matter.
What is the mid-parent height formula?
For boys: (father's height + mother's height + 5 inches) / 2. For girls: (father's height + mother's height - 5 inches) / 2. This estimates the average expected adult height based on parental genetics.
