All the Caps are made to order to your headsize, so please check you have ordered the right size before ordering.

You also have the chance to exchange your cap upto a month after ordering, if you want a slightly smaller or bigger fit. Just see the size exchange/returns page for info on exchanges.


There is only ONE measurement you need and that is around the widest point of the forehead and back of the head. You can do this with either cm or inches and then use the chart below to pick the cap size to order.



Once you have your headsize, firstly have a think about how tight you would prefer your cap to fit. Sometimes if a hat is too tight it can essentially give you a headache later in the day & quite simply everyone's level of comfort is slightly different! So the below is only advice, as ultimately it's your own personal preference!

For a comfortable fit, firstly it depends on the cap style! So for basics and panel caps I would recommend sticking as close to your headsize as possible, but don't go smaller! This is based on feedback from previous customers and my own experience of wearing them on a regular basis.

Some of the trapper hats and fisherman caps it can be a lot more comfortable to be a bit bigger, but the basic caps you don't really want to blow off your head, so try to stick as close to your actual headsize as possible (so ideally no more than 1/4" larger than what you measure your headsize to be e.g.) 

If you do want a cap with a bit of room, then go slightly bigger than your head measurement, but only by a little, so approximately 1/4" for a snug fit or upto 3/4" for a roomy fit. Trapper caps don't need to be as tight if you wear them a lot with the earflaps down, (this is how I wear them all day long!)

Also think about your hair style and how you often wear your hair up or down.


Not a problem! Headsizes range from as small as approximately 20" for adults right up to 26" and for kids between 16" - 23" but only APPROXIMATELY. I've seen lanky friends with 24" heads and have made hats for opera singers right up to 25". There is no predictable rule and for kids especially heads are obviously still growing, so this changes. At the moment all the caps on the website are available to order in XXS-5XL, but I've recently made upto 8XLs too.

The above table is just a guide & custom requests are definitely always available. So if you can't see your size in the chart then get in touch and drop an email. There is no extra charge for a cap already listed on the website to be made in your headsize. The only extra fees would be if it is a completely new tailored style. For custom caps see here.

Altering the cap patterns to a particular size is just an everyday part of hatmaking, so custom sizing is intentionally accessible. The ultimate goal is to have more sizes including kids headsizes available to order from!

This also goes for other styles that you have always wanted to get or have been trying to find. I am constantly patterning behind the scenes working on new styles, and just because it's not for sale on the website yet doesn't mean I can't make it. Chances are I have made it whilst working as a theatrical milliner (where this all started) and I eventually want to add as many cap styles as I can for sale. So don't be afraid to get in touch!


Traditional Headsizing has many formats and each company seems to use a different one depending on their heritage, country or preference. This is why you will sometimes see different numbers. If you already know your headsize or one you prefer then use this chart to work out transferring it to size chart used by The Capalog.
