Hat Size Guide

Everyone is unique, however these charts were designed to give you a rough idea of average circumference for project planning purposes. These yardages are rough estimates, as yarn usage changes depending on stitch pattern. You’ll need approximately 2 inches of negative ease for your hat’s circumference; that means the circumference of the actual hat should be approximately 2 inches smaller than the circumference of your head.

These yardages were estimated using a gauge of 5 sts per inch and a stockinette stitch. The heights and yardages were calculated taking into account a folded brim or a slouchy style hat; fitted hats will be shorter and may require less yardage.
