Hats off!
Always measure the inner hat for circumference. Continue extending the soft, malleable tape measure around the inside of the hat until both ends meet. There is your hat size. Done!
Measuring
your forehead
Beginning approximately 1/8 above your ears, place a string or a ribbon around your forehead extending to the back of your head. Be sure to measure the widest aspect of your head. Above your head and above your eyebrows. Typically most hats and heads measure between 21" and 24". Lay out the ribbon or string the length of the ruler, read out the numbers and now you have your head size.
