Size Chart

Hats are listed on the website are labeled with a circumference and/or with an age range such as “adult.” This size chart gives some meaning to those references. Also, if you ask me for a custom order for a person of a certain age/gender, I will be referring to this chart to size hats. This is especially important for children’s hats, since they vary so much in size! I hope the posting of this chart helps us all stay on the same page. Thanks!

I’ve done a good bit of research online about how to size hats properly, especially for children. Even still, there’s a lot of variation in sizes, so please check the measurements to be sure your hat will fit!
