Find your Fit

To measure your head for a New Era hat, you can use a flexible tape measure to find your cap size:

1. Place the tape measure in the middle of your forehead.
2. Wrap the tape measure around the circumference of your head, about half an inch above your eyebrows and ears.
3. Ensure the tape measure is straight and not twisted.
4. Make sure the tape measure feels snug, but not too tight, where the sweatband will rest.
5. Use the New Era size chart above to convert your measurement from inches or centimeters to a fitted size.
6. 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.

 * New Era 59FIFTY fitted hats are crafted with precision, but minor variations in fit & color may occur due to differences in their materials, manufacturing processes, and dye treatments. We are happy to accept a return on most items if there are issues with the sizing or color. *
