Measuring Your Hat Size
To find your general Hat Size using a flexible tape, measure your head circumference above the ears, approximately 1 inch above your eyebrows and about ½ inch to 1 inch above the ears (as hat brim should not touch your ears). Note: The UK and US have traditionally used Imperial Sizes (measured in 1⁄8 increments) that are are out of phase by one unit with each other. To reduce confusion please always use CM to measure your size.

Headwear Size vs Hat Size
Different types of headwear are worn in different positions on the head, a person actually has multiple Headwear Sizes depending what is type of headwear is being worn and the circumference around the head where the headwear is positioned at. Using the initial Hat Size as a Baseline (as measured above), one can extrapolate some general rules of thumb (or maybe rules of head!) to find the other probable headwear sizes without having to measure them all.
Subtract one size for Berets and Boater Size (As usually worn higher on head)
Use the standard Hat Size for Top Hats/Bowlers/Fedoras/Panamas and most hats
Add one size for Tweed / Flat Cap Size (Usually worn at a longer slanted angle behind the ears)
Add two sizes for Winter Headwear Size (That go over the ears increasing the overall size)

Measuring Your Head Shape
Heads are not the same, even if you measure the same Hat Size as someone else. Some people have round heads, other elongated ovals, or you can be tapered at the front, and often there is the odd bump also to take into account too. To try to accommodate most people, hat makers make headwear in shapes called "Ovals". Whilst there is no regulated system, there are considered to be at least three generic Head Shapes.
Round Oval - Approx. 5/8 inch longer than it is wide
Regular Oval - Approx. 1&3/8 inches longer than it is wide
Long Oval - Approx. 2&1/8 inches longer than it is wide
The difference in Ovals size is also dependent on the block the hat was made from, they can even vary from hat makers and between hat styles, Most hats are made in a Regular Oval shape, which allows the hatter to more easily alter it to an individual if they are a round or long oval.
Soft hats such as Panamas and Cloth Caps, the fabric can easily mould to an individual's head, but with stiff felt bowlers/toppers and silk top hats the Head Shape is as important as the Hat Size, and a Hat Fitting becomes paramount. Your Head Shape can be measured at our workshop using specialised tools such as a Conformateur and Formillion (pictured below) so that we can make a model of your shape.
If you are unable to make it to our Workshop we often attend various Events & Shows throughout the year, alternatively we have created a Hatter's Curve so you can also DIY measure your size and shape. The best option is always to pop in for an appointment and we can measure you.
After measuring the Hat Size and Head Shape, a Hat Fitting Service can reconform a hat from it's standard off the shelf shape to a one more suited to your head shape. If you have already bought a hat or inherited a hat elsewhere we can usually assist too, provided that it is in good condition and the correct size. Depending on the type of headwear construction type we use various traditional techniques to heat and remould the headwear, so it may feel more comfortable and look better and hopefully be less likely to fall off!
