Genetics: There are by definition 3% of the normal adult population that are classified as having an over sized head & 3% that would be considered small. When i see it in a kid i usually find either mom or dad has one also. There are syndromes & birth defect (hydrocephalus) that can also produce a large head, but by far the largest group just inherited the feature.
