Cranial Index

the ratio of the maximum breadth of the skull (transverse diameter) to its maximum length (longitudinal diameter) expressed as a percent. The cranial index is used in anthropology to characterize the shape of the skull in the horizontal plane. Low values reflect a relatively long and narrow skull. An index not greater than 74.9 is indicative of dolichocrany, whereas indexes of 75–79.9 and 80 or greater reflect mesocrany and bradycrany, respectively. The cranial index of humans does not reflect intellectual capacity. The index is used as a means of distinguishing anthropological racial types from skeletons.
