The Tilley hat fits more comfortably than other hats - so it often looks better, too. It’s designed to be worn low on your head and slightly loose, and should be held on by gravity.
To ensure ease and comfort, please add 1-2cm (0.4-0.8") to your measured head size for the best fit, depending on how snug you like to wear your hats.
How to measure your head
1. You’ll need a fabric tape measure - or a piece of string and a ruler.
2. Wrap the fabric tape measure or string around your head.
3. The measuring tool should be level.
4. It should rest just above your eyebrows.
5. Do not wrap the measuring tool too tightly around your head.
6. If using a string, compare the length against a ruler.
7. Take the measurement from the fabric tape measure or string and add 1-2cm (0.4-0.8") to ensure ease and comfort, depending on how snug you like to wear your hats.
8. Compare that measurement to the chart below to find your hat size.
