To measure easily, wrap a string around your head across the top of your eyebrows.
Measure the string.
This is how these hats will circle your head.
These Yooper Chooks are a full and generous hat made of fleece that owns its’ stretch. The measurements really do not have to be spot on exact. Since the fleece stretches a bit, the fit is up to whether you want a snug fit, or not.
Small —17.5 to18.5 inches (Usually fits the toddlers, not babies.) FITTED SIZES 6 TO 6 1/2 SMALL
Medium 20 to 21 inches ( If your head is on the small size for an adult, then medium would be the one to choose, if you don’t have the measurement available.) FITTED SIZES 6 5/8 TO 7 1/4 MEDIUM
Large 22 to23 inches (Fits about 70% of adult heads, men and women.) FITTED SIZES 7 1/4 TO 7 5/8 LARGE
Extra Large 24–25 inches ( Both women and men have extra large heads. And, if one likes to wear a brimmed ball cap under their chook, then this works really well with the Extra Large.) FITTED SIZES 7 3/4 TO 8 1/4 X LARGE
