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.
If you already know your regular (non-Tilley) hat size, we recommend that you select one size larger when you order your Tilley. For instance, if you’re normally a 7¼, order a 7⅜. However, to be sure, we recommend you use our measurement and sizing instructions below.
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 compare it to the chart below to find your hat size.
