How to Measure Yourself at Home
To find your correct size, you’ll need a flexible measuring tape (or string and ruler):
Wrap the tape around your head at the same level as a baseball cap — just above the eyebrows and ears, and around the widest part at the back.
Record your head circumference in inches or centimeters.
Use the chart below to find your recommended size based on head circumference or hat size.
