Not sure what size you are? Read below how to find out which size fits you.
Take a measuring tape and place it around the circumference of the head, slightly above the ears, with the tape held fairly closely to the head. Measure your head and then compare the measurement with the size above to find your hat size. If you don’t have a tape measure, then use a piece of string or wool to measure around your head and then check the length using a ruler or other measure.
