If you're looking for an average, measure your own head first and compare with other answers and then take an average. Or, take my word for it: ~9" long & ~6" wide. Really.

There is no fixed size of human head. It varies from person to person as other body parts also differ. For some the head is very big whereas for others it is very small. So it will be futile to guess the average size of a human head , it will be somewhere around 57cm.

There is no true measurement that determine what is the average head size in adults. Everyone is different in proportion to his/her own structural composition. A persons ethnic background is also a key factor in relation to head size. A Native American for example will generally have a larger head then an African American.
