Is Head Size Genetic?

Im a 16 yrs old male and have a somewhat smaller head size then most people.
I was just asking is head size genetic?
Cause my dad has a somewhat smaller head too.
Im suggesting that i inherited the same head size from him.
Could this be true?
Please and Thanks!

Familial correlations in birth weight and gestational age have been explained by fetal and maternal genetic factors, mainly in studies on offspring of twins. The aim of the present intergenerational  study was to estimate and compare fetal and maternal genetic effects and shared sibling environmental effects on birth weight and gestational age and also on crown-heel length and head circumference.Hope it will help.
