Your hat size is M (EU 57, US 7 1/8).

  • Your EU hat size is 57 (equivalent to US 7 1/8 and UK 7).
  • This falls in the average range for adults (57-59 cm). Most standard hat styles are readily available in your size.

Next stepAlways try a hat on before buying if possible. Styles differ: a fedora and a baseball cap from the same brand can fit differently even at the same size. Use hat tape or foam inserts to fine-tune the fit.
