Anything to measure the crown of your head and a ruler.
Step 2 - How Do I Measure Myself?
Wrap your measuring tool around your head. Make sure the bottom touches right above your eyebrows while going straight around your head. Compare that measurement against a ruler to get your size. Enter the number below and press "NEXT"
Step 3 - This Is Your Hat Size
You can save it to your profile or start shopping your size right now.
Like footwear, your Tilley Hat must be sized properly. To find your hat size, use a tape measure and draw it right around your head. For the best-looking and most comfortable fit, please make sure that the bottom of the tape touches right above your eyebrows while resting straight around your head. Hold it there comfortably and do not pull tight! Tell us this measurement in inches or centimetres. We’ll take it from there.
You may also refer to our Hat Sizing Chart below for an easy reference to your Tilley Hat size.
If you already know your regular (not a Tilley) hat size, please ask for one size larger when you order your Tilley. For instance, if you’re sure you’re a 7¼, order a 7⅜.
The Tilley Hat fits more comfortably than other hats. It’s designed to be worn low on your head and slightly loose. It should be held on by gravity, not by painful pressure on your forehead! When it’s windy, use the cord!
