How to Measure Your Hat Size
- 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.

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?

Hello!
I am making two different size bucket hats. The circumference are 59cm and 57cm.
Now I am facing a problem on the crown height and the brim width. Should the different size hats have different size height and brim width? How should the grade rule be?
Thank you!
