How to Measure Your Head

  1. Use a soft measuring tape (or a string you can measure afterward).

  2. Wrap it around your head about 1 inch above your eyebrows and ears, where a hat would naturally sit.

  3. Keep the tape snug but not tight.

  4. Compare your measurement to the chart above to find your ideal size.

 

Fit You Can Feel

Our big head hats are thoughtfully engineered with:

  • Generous crown depth

  • Wider internal circumference

  • Adjustable inner bands or drawstrings (on select styles)

This ensures a secure, comfortable fit without squeezing, headaches, or red marks — problems commonly caused by standard large head hats that aren’t truly designed for bigger sizes.

 

Why Proper Sizing Matters

A correctly sized hat not only feels better but also provides better sun protection. When a hat fits properly, the brim sits correctly, offering consistent coverage and maximizing the benefits of UPF 50+ sun protection.
