Determining Your Hat Size
Measure the circumference of your head where the hat will be worn. The chart below shows the relationship between the circumference measurement and the hat size.
We use UK hat sizes; the table shows the conversion to US and European Metric sizes.
As head shapes and personal preferences about how the hat is worn differ widely we use the hat size only as a guide.
