I always think of myself as having a large head for a woman. I had to measure mine this morning because I was looking to by a hat on line. My head measures 23 1/4 inches.
I think the average is about 24 inches for men and 22 inches for women. I did read one place that says ethnicity plays a role in that.
Friends Have Always Told Me I'm A "Bit Thick Between The Ears".......But I Think That Relates To Density Rather Than Size... Cheers Glen.
Some things I've read say that head size equals brain size which equals higher IQ. I don't know that I believe that. I've known some real big-headed dumb asses.
