How to Predict Your Child’s Height: Genetic Height Calculation Formula
It's said the formula's accuracy is about 70%.
Genetic height:
Boy's height = (Father's height + Mother's height + 13cm) ➗2
Girl's height = (Father's height + Mother's height - 13cm) ➗2
Postnatal growth height:
Your own growth potential is 7.5cm, which represents the range of influence from postnatal factors such as living environment, habits, and exercise—adding or subtracting within that 7.5cm margin.
If lifestyle habits are poor, you might end up shorter than your genetic height; if they're good, you could grow taller than your genetic baseline.
Currently, height enhancement has become a profitable industry. Hormone injections can cost over 100,000 RMB per year, while cheaper supplements run about 2,000 RMB per month. From this angle, it's easy to understand why many women consider height when choosing a partner—it's essentially about optimizing genes.
