Adult height (target height from parental height)

Expected adult height from parental and grandparental heights and the current body height – with probability range

Child

Sex

male female

Age

Current height (cm)

Measured standing, without shoes.

Parents

Mother’s height (cm)

Father’s height (cm)

Measured parental heights are better than reported ones: reported values are on average too high, and from middle adulthood onward height decreases again – the best-known systematic error of any target height calculation.

Grandparents (optional)

Maternal grandmother (cm)

Maternal grandfather (cm)

Paternal grandmother (cm)

Paternal grandfather (cm)
