Hat Size Chart

To measure your head and determine your hat size use a flexible tape measure (the kind used for dressmaking, not carpentry!) and measure around the circumference of your skull starting on your forehead and going around, above your ears and just under your occipital bone (the the part the protrudes the furthest on the back of your head), all around to the front.

Compare the resulting measurement with the chart below.  If you are between sizes choose the next largest size.  If you plan to have a different hairstyle or a wig try to take the measurement with that in place.
