Where do I measure my head?

Measure around the widest part of your head, typically about 1 inch above your eyebrows and just above your ears.

What if my head size is between two sizes?

Always choose the larger size. A slightly loose hat can be adjusted with sizing tape, but a tight hat will be uncomfortable.

Does hair affect hat size?

Yes, if you have thick hair or wear it in a style that adds volume, measure your head with your hair how you plan to wear it under the hat.

📏 How to Measure Your Head

1. Proper Tape Placement

The most important step for an accurate fit:

Diagram showing proper head measurement for hat sizing: tape 1 inch above eyebrows and just above ears

Place tape about 1 inch (2.5cm) above eyebrows.
Ensure tape is just above your ears.
Keep the tape level all the way around.

2. Know Your Head Shape

Shape affects fit as much as size:

Diagram comparing Long Oval vs Round Oval head shapes

Long Oval: Longer front-to-back (most common).
Round Oval: More circular shape.
If you have a round head, you might need to size up.

💡 Fit Check: Tight vs. Right

Comfort is key!

A hat should sit comfortably above your ears without leaving red marks on your forehead. It should be snug enough to stay on in a breeze, but loose enough to not give you a headache.

✓ Correct: Level, comfortable, no pressure
✗ Incorrect: Too high, red marks, headache

💡Quick Answer

Use a flexible tape measure. Place it about 1/8 inch above your ears and across the mid-forehead. Enter this number (in inches or cm) below to find your perfect hat size.
