The Skull Theory

The Skull Theory can be used as a home technique  for predicting gender, although fans claim it has a 92% accuracy rate there is no medical or peer reviewed evidence to support this.

Most important skull differences between men and women are described below.

The Skull Theory


A. The mans cranial mass is more blocky and massive compared to the females which is rounder and tapers at the top.

B. Temporal Ridge – runs along the outer side of the upper skull creating the square shaped of the upper head. More prominent in men than women.

C. A woman’s supraorbital margin (the ridge above the eyes) is sharper, while the males is rather round and dull.

D. The Zygomatic bone (the cheekbone that lies under the lower eye ridge) is more pronounced on the male skull.

E. The Mandible (lower jaw) bone of a woman is rounded, while the male’s is squared.

F. Frontal bone forehead structure terminates at the brow. The male forehead is lower and more slopping.

G. Men have a deeper cranial mass.

H. The superciliary arch is large and pronounced in the man.

I. A males gonion (most posterior inferior point on angle of mandible) is more flared out and sharply angled.

J. The teeth of men tend to be larger
