What Hat Size would be a small medium?

A small medium hat size typically corresponds to a size 7 to 7 1/8 in U.S. hat sizing, which is approximately 21.25 to 22.25 inches in circumference. In some brands, it may also be labeled as a size small (S) or medium (M), depending on the specific sizing chart used. Always check the manufacturer's sizing guide for the most accurate fit.
