The Right Fit

Find the Tilley for you.

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. Measure the circumference of your head, approximately 1cm above your ears.

3. Add 1-2cm to your head measurement, depending on how you like to wear your hats, to ensure ease and comfort. 

4. If using a string, compare the length against a ruler. 

5. Reference the chart below to find your size.
