Häufig gestellte Fragen

How accurate is the mid-parental height method?
It provides a rough estimate within ± 8.5 cm (± 2 inches). Genetics accounts for about 60-80% of adult height, but nutrition and health also play a role.
Why is 13 cm added or subtracted?
The 13 cm (5 inches) adjustment accounts for the average height difference between adult men and women.
At what age does a child reach adult height?
Most girls reach adult height by 14-16, and most boys by 16-18. Growth plates typically close by age 18-20.
