How do I get the correct sized Tilley Hat?

Hat Fitting Guide


Most hat makers make 4 or 5 sizes; Tilley makes 13.

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 centimeters. 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! For the proper fit, you should be able to easily insert two fingers, flat, between the middle of your forehead and the front of the Hat. The Hat should be loose enough that you can rotate it to the left and right, and lift it up and down, without friction on your forehead. When it’s windy, use the cord!

Size Chart


You’ll find our ‘round’ crown styles (i.e. T3, LTM3) and our ‘oval’ crown styles (i.e. T4, LTM6, LTM5 etc.) measure the same circumference but feel slightly different on your head. If you can fit two fingers flat between your forehead and Tilley Hat then the size is correct, even though they may feel different due to the crown style. If used to a ‘round’ crown style, it may take you a few days to get used to an ‘oval’ crown style.


Much like your clothes, individual fabrics feel different on, even when they’re the same size. For example, your lightweight nylon LTM6 Tilley Hat will feel different than your TH4 hemp Tilley Hat. Due to the varying fabric weights, each Hat offers its own unique feel.

If your new Hat or Cap doesn’t fit, send it back. If the color doesn’t suit you, send it back. If it has not been worn or washed, we’ll exchange it for one of the right size or color. If your new Hat or Cap isn’t quite what you expected, we’ll refund the purchase price.
