Sizing Chart

Welcome to our hat sizing chart! We understand how important it is to find the right fit for your hat, so we've put together this guide to help you make the best choice.

To get started, take a measuring tape and measure around the widest part of your head, which is typically just above your eyebrows and ears. If you don't have a measuring tape, you can use a string or ribbon and then measure the length of the string or ribbon with a ruler.

Once you have your head measurement, refer to the chart below to find your hat size:


Head Circumference (in) Head Circumference (cm) Hat Size
21 1/4 - 21 5/8 54 - 55 S
22 - 22 3/8 56 - 57 M
22 3/4 - 23 1/8 58 - 59 L
23 1/2 - 23 7/8 60 - 61 XL
24 1/4 - 24 5/8 62 - 63 XXL
25 - 25 1/2 64 - 65 XXXL
O/S Up to 61 One Size Fits Most


If you fall between two sizes, we recommend choosing the larger size for a more comfortable fit. Keep in mind that some hats, such as baseball caps or beanies, may have a more adjustable fit due to their stretchy materials.

It's important to note that hat sizes may vary depending on the brand or style of the hat. We always recommend checking the specific sizing information for the hat you're interested in to ensure the best fit.
