The cephalic index is calculated as maximum head breadth divided by maximum head length multiplied by 100. An index above 80 is classified as:
- A Brachycephalic ✓
- B Mesaticephalic
- C Dolichocephalic
- D Platycephalic
Explanation
Cephalic index below 75 is dolichocephalic (long headed, typical of Caucasoids), 75 to 80 is mesaticephalic, and above 80 is brachycephalic (short headed, typical of Mongoloids). Platycephalic refers to a flat headed skull and is not one of the three standard racial categories of the index. The index is used in race determination from an intact skull when other features are unavailable.
