| Curious? Have you ever wondered how hat sizes are determined? Hat sizes are calculated by dividing head circumference in inches by the value of pi, which is known to be the ratio of the circumference of a circle to its diameter, and which is said to have a value of 3.14. For example, a head circumference of 22 inches divided by 3.14 equals 7.00-or a size 7 hat.
