To measure your head for a custom hat, you’ll need a tailor’s tape measure (the soft, flexible kind) and a friend or a mirror to help. Follow the instructions below (or watch the video) and use the chart to convert to your US hat size.
Items Needed:
• Tailor’s measuring tape (with centimeters) or string and a ruler
• Mirror
Steps:
1. Wrap the measuring tape around the widest part of your head and about a finger’s width above your ears and eyebrows.
2. Write down the measurement in centimeters.
3. Repeat this process until you get the same measurement twice.
That’s it! Share this number with your hatter (hopefully me), and you’re ready to go. Use the included conversion chart to find your US hat size.
