How to find the right size?
To measure your head for a New Era hat, you can use a flexible tape measure to find your cup size:
- Place the tape measure in the middle of your forehead.
- Wrap the tape measure around the circumference of your head, about half an inch above your eyebrows and ears.
- Ensure the tape measure is straight and not twisted.
- Make sure the tape measure feels snug, but not too tight, where the sweatband will rest.
- Use the New Era size chart above to convert your measurement from inches or centimeters to a fitted size.
- If you're between sizes, We recommend rounding up.
- You can also use a piece of string to measure your head and then measure the length of the string with a ruler.
