Genetic Target Height & Range
The Mid-Parental Height Calculator estimates a child's genetic height potential from both parents' heights, as a way to contextualize the child's own growth-chart centile and screen for familial short or tall stature. It applies a different offset for boys versus girls and reports a target height range around the calculated mid-parental height.
This reflects the average height difference between adult men and women; the calculator adds 6.5 cm to the parental average for boys and subtracts 6.5 cm for girls, per the formula shown in the app.
The app reports mid-parental height +/- 6 cm as an expected target range, reflecting normal variation around the genetic estimate.
No — the app's own disclaimer states this is a genetic potential estimate only, and actual adult height is also influenced by nutrition, health, and environmental factors.
The app validates mother's height between 120-200 cm and father's height between 130-220 cm.
No — this tool only computes the mid-parental height estimate; it's meant to be used alongside, not instead of, a standard growth chart when interpreting a child's centile.
