How to check your hat size
A good hat needs to fit right. Here’s how you do it. Start with a measuring tape (or a piece of string you can measure later) and wrap it around your head, placing it where your hat will sit—typically, at the middle of your forehead and about 1/8″ above your ear. Hold the tape firmly, but not uncomfortably tight. Find your size using the chart below. If your measurement falls between sizes, order a size up.
