Don't know your hat size? Here's how to find out. Wrap a cloth measuring tape or string around your head at the point at which your hat normally sits (~ 1/2" above your ear and across mid-forehead). Pull the tape or string tightly enough to get an accurate measurement, but not uncomfortably so. Take the measurement and match it to the next largest interior circumference listed above.
A word of caution: Most men actually wear a size large hat instead of a medium. Just because you are a medium in pants, shirts, etc. doesn't mean vour hat size is a medium too!
