How to Measure Your Hat Size

Follow these simple steps to measure your head accurately: What you'll need:

• A soft measuring tape or a piece of string and a ruler
• A mirror or a friend to help
• Pen and paper to jot down the size

Step-by-Step Instructions:

• Place the measuring tape around your head about 1/8 inch (0.3 cm) above your ear and across the mid-forehead—right where your hat will sit.
• Keep the tape snug but not tight. It should feel comfortable, like a hat would.
• Note the measurement in inches or centimeters.
• If using string, wrap it the same way, mark the length, then measure it with a ruler.
• Find Your Hat Size with the corresponding size on the below hat chart

Pro Tips:

Measure more than once to ensure accuracy. If you're between sizes, we always recommend sizing up for a more comfortable fit.

It is also known that different suppliers do in fact follow different sizing metrics. So, the chart, although universal, may vary from one hat maker to another.

I don’t have a measuring tape, can I guess my size?
