Male Vs Female Skull in 8 easy steps / by Dan Crossland

Whether it be drawing, or sculpting in clay or digital, knowing  the key differences between the male and female skull are fundamental to creating a convincing realistic or stylised human head,

Here are 8 easy guidelines that I have learned through my anatomy projects, which I hope you find useful for your own work. I have separated the main differences between the male and female skull. However, that is not to say that features mentioned here are not found in their opposites, but as a general rule the following applies. 

Lets take a look at the major differences between the male and female skull:

Masculine Skull
1 -  Projection of the brow ridge and nasal eminence beyond the root of the nose (ref-1)
2 - Projection of the forehead at an inclined angle (ref-2)

Feminine Skull
3 - Reduced weight and volume, thinner skulls walls, especially notable on the brow ridge and nasal eminence (ref-3)
4 - Mandible is smaller with a more open angle (ref-4)
5 - Bony processes and projections are smoother with less definition where the muscles insert, supra-mastoid crest,        nuchal lines, zygomatic process, and supraorbital ridge etc (see blue markers)
6 - Forehead more vertical continuing directly with the nasal bones (ref-5)
7 - The parietal and frontal eminences are more developed, more room for brain cells :)  that's probably why females      are so good at multi tasking (ref-6)
8 - Flattened vertex (top of skull) (ref-7)
