Frequently Asked Questions
How accurate is this prediction?
The Mid-Parental Height method is accurate within about ±5 cm for roughly 85% of children. It is a statistical estimate, not a medical measurement.
When does growth stop?
Girls typically reach their final adult height by age 16–17, while boys usually finish growing between ages 18–21.
How can my child reach their full height potential?
Proper nutrition, 8–10 hours of sleep, regular physical activity, and prompt treatment of any health conditions all support reaching genetic height potential.
Does this account for bone age?
No. A doctor’s bone-age X-ray can reveal additional growth potential beyond this estimate, which this calculator does not include.
