Use a soft tape measure (or string that you can hold up to a standard tape measure) to determine your head’s circumference.
Place the string or tape around your head above your ears, and across the eyebrows, measuring your head exactly where the hat will sit.
Hold the tape firmly, but not too tightly. If you fall between measurements go for the next size up.
