The honest truth is that hat sizes vary from brand to brand and even style to style within brands. Plus, our heads aren't uniformly shaped - some of us have long heads, some very round - which can affect fit. For this reason we measure the circumference of all of our hat and list that in centimeters (more accurate than inches and no weird fractions).
Regarding fit: it's personal. Some of us like hats that we can tuck one or both ears in, some like a jaunty tilt, some like a classic 1940s high fit. There's no wrong way to wear your hat. Also, keep in mind that some styles are firm and some are soft. Stiff hats tend to fit smaller, soft hats are a little more forgiving.
If you have a question about fit or sizing, call us at 937-222-4287 and we'll walk you through styles and shapes and help you understand what to look for when you're shopping.
