58cm to 60cm or up to a 23" diameter head. Known by many names and used by many different cultures (Dutch, Greek, German, etc) across Europe, this Fisherman cap will be sure to please the tastes of those who appreciate this classic style or make a great gift.
Measuring for your head size is both an art and a science. You can use a tape measure (or a length of string that you will have to hold up to a tape measure) to determine the length. Place the string or tape around your head about 1/8" above your ear, across the mid-forehead, completely circling your head. Hold the tape firmly, but not too tightly. Basically you need to measure your head exactly where the hat will sit. If your measurement falls between sizes, choose the next largest size.
