Understanding Mid-Parental Height
Height is a complex trait influenced by genetics, nutrition, and environmental factors. This tool uses the Mid-Parental Height Method, a standard medical estimation technique widely used by pediatricians to determine a child's "genetic target" range.
How the Formula Works
The calculation is based on the biological parents' height, adjusted for the child's gender:
- For Boys: We average the parents' heights and add a genetic offset. The formula effectively adds 13cm (approx 5 inches) to the mother's height before averaging.
- For Girls: We average the parents' heights and subtract a genetic offset. The formula effectively subtracts 13cm from the father's height before averaging.
- Adjustment Note: This creates a ±13 cm total gender adjustment applied in the formula (averaged internally to ~6.5cm from the mean).
Why We Ask for Age & Current Height
While the Mid-Parental method relies purely on genetics, we ask for Age and Current Height to provide context. The tool compares your child's current stature against general growth curves to see if they are tracking consistent with, above, or below their genetic prediction.

Factors such as nutrition, sleep, and health conditions can significantly alter final adult height. Always consult a pediatrician for growth concerns.
