[6] One study in the United States estimated the average human head circumference to be 57 centimetres (22 + 1 ⁄ 2 in) in males and 55 centimetres (21 + 3 ⁄ 4 in) in females.

It is distinct from phrenology, the pseudoscience that tried to link personality and character to head shape, and ...
Brain size. The size of the brain is a frequent topic of study within the fields of anatomy, biological anthropology, animal science and evolution.

the ratio of hip circumference to shoulder circumference varies by biological sex: the average ratio for women is 1:1.03, for men it is 1:1.18. [9] legs (floor to crotch, which are typically three-and-a-half to four heads long; arms about three heads long; hands are as long as the face. [10]
As of 2015, a systematic review of 20 studies, of up to 15,521 men, who were measured by health professionals rather than themselves, concluded that the average length of an erect human penis is 13.12 cm (5.17 in), while the average circumference of an erect human penis is 11.66 cm (4.59 in). [2] A 1996 study of flaccid length found a mean of 8 ...

The height, weight, and head circumference of a child can be compared to the expected parameters of children of the same age and ...
