Diagram showing head circumference measured around the position where a hat will sit.
Measure around the actual wearing position before comparing western-hat size references.

Western hats need both circumference and shape awareness

Measure at the exact angle where the hat will sit and compare the nearest fitted-size row.

Felt and other shapeable materials can behave differently from rigid caps, so use the maker’s fitting and shaping guidance when you are between sizes.
