Has anyone tried to match their face features to a hat using the golden ratio? I have studied various photographs of persons with a hat fit that looks good to my eyes; all of them follow quite nicely the golden ratio with a very small margin of error. To illustrate my point, a person with a face length of 1 (measured from the chin to the brim) should choose a hat that has a width of 1.618 (the width of the crown plus two times the width of the brim). Again, the height of the crown should be 1/1.618 = 0.618.
