How to Measure Your Head

  • Use a flexible measuring tape or a string.
  • Wrap it around your head about 0.3 cm (1/8 inch) above your ears and across your forehead—where the hat will sit.
  • Hold it snug but not too tight.
  • If you're between sizes, go for the larger one.

Sizing Tips

  • If you already own a well-fitting hat, check its size for reference.
  • Hat sizes may vary by brand, especially between UK and North American manufacturers.
  • Measuring in centimeters or inches is more accurate than relying on standard hat sizes.
  • Like clothing, hats can fit slightly differently depending on the maker.
  • If you're unsure, check the sizing details on the product page or contact us—we’re happy to help!
