What is average face length?

As an AI language model, I don't have access to visual information to provide accurate details on face length. However, the average face length varies depending on age, gender, and ethnicity. In general, adult males have longer faces than adult females, and people of African descent tend to have slightly longer faces than people of European or Asian descent. Face length is typically measured from the hairline to the bottom of the chin. The average face length for adults is around 9 to 10 inches. However, it's important to note that there can be significant variations in face length due to individual differences in bone structure, diet, and other factors.
