How to Choose Your New Era 59FIFTY Hat Size

The New Era 59FIFTY is a true fitted cap. There is no strap, snap or elastic, so it only looks right when the size matches your head. Sizes run in eighth-inch steps from 6 7/8 up to 8, and the number is the diameter of the sweatband in inches. Here is how to find yours.

Measure your head

• Use a soft tape measure. No tape? Wrap a string or phone charging cable around your head and measure it against a ruler.
• Wrap it where the cap actually sits: about 1/8 inch (a finger-width) above your ears and across the middle of your forehead, just above the eyebrows.
• Keep the tape snug but not tight, and make sure it sits level all the way around.
• Read the measurement in inches or centimeters and find it in the chart below.

Crown shapes change the feel

The number on the sweatband is the same across every 59FIFTY, but the crown shape changes how the cap sits. The standard 59FIFTY has a structured, mid-height crown. The Low Profile version has a shallower crown that sits closer to the head and can feel a little snugger in the same size. The A-Frame has a taller, flatter front panel with a more squared look. If you move between these, try them on rather than assuming your usual size.
