Hat Measurement & Sizing Guide

{The pattern for the hat that is pictured in my Pinterest pin can be found here.}

Below is a list of average hat sizes, in circumferences and lengths, for all sizes. I am often asked by my customers which guidelines I use, so I thought it would be helpful to post them here on my website. Keep in mind that these are average recommendations, and my personal preferences. :-) Please always let me know if you have more questions about sizing, and I'll be happy to help!
