How to Measure Your Hat Size at Home and Pick the Right Fit

Most fit problems we see at the counter come from guessing. Someone wore a 7 1/4 ball cap once, or a friend said they look like a large, and the hat that shows up either rides on top of the head or drops to the eyebrows. A felt hat with a leather sweatband is far less forgiving than a stretch-fit cap, so five minutes with a tape measure saves a return trip and a week of waiting.

This guide covers how to take the measurement, how to turn it into a fitted size, what to do if your head is more oval or more round than average, and how a new hat should feel the first time you put it on.

Measuring your head at home

You need a soft tailor's tape. A metal tape measure will not wrap properly and will read long. No soft tape in the house? Use a length of string or a phone charging cable, mark where it meets, then lay it flat against a ruler.

1. Stand in front of a mirror with your hair styled the way you usually wear it under a hat. If you wear a ponytail or braid low on the back of the head, take it down or note that it will change the reading.
2. Place the tape about 1/8 inch above your eyebrows in front, run it just above the tops of your ears, and pass it around the fullest part of the back of your head. That line is where a sweatband actually sits.
3. Keep the tape snug but not tight. It should lie flat against the skin without pressing a dent into your forehead.
4. Read the number where the tape overlaps, then take it off and measure twice more. If the readings differ, use the largest one.

Ask someone else to hold the tape if you can. It is surprisingly hard to keep the tape level at the back when you are doing it alone, and a tape that dips toward the neck will add a size.

Converting inches to fitted sizes

Fitted western hats are labeled in eighth-inch steps that come from the diameter of the hat opening, which is why the numbers look odd next to a tape reading. Find your circumference in the chart below. If you land exactly on a line, that is your size. If you fall between two lines, read the section on in-between sizes before you order.

Most of the Stetson felt and straw styles we carry run 6 3/4 through 7 3/4. A few go wider. The Skyline 6X, for example, is offered from 6 1/2 up to 8, and the Rancher 6X runs from 6 5/8 to 8, so if you measure outside the usual range those two are worth a look. Some lower-priced wool and outdoor styles use S, M, L and XL instead of fitted sizes. Check the size list on each product page rather than assuming one system covers every hat.

Our disco cowboy hats are simpler. The Plush Party Faux-Fur and Dancehall Retro come in one size M, which works out to roughly 56 to 58 cm, or about a fitted 7 to 7 1/4. If your tape reads well outside that, a fitted western style will sit better than a one-size party hat.

Oval heads, round heads and why it matters

Circumference is only half the story. Two people with the same 22 5/8 inch reading can have very different head shapes. A long oval head is narrow at the temples and long front to back. A round head is wider at the sides and shorter front to back.

Most fitted western hats are blocked on a regular oval, which suits the largest group of people. The Corral 4X, for instance, lists a regular oval crown. If your head is close to that shape, the sweatband touches evenly all the way around.

If your head is rounder than the block, you will feel pressure at the temples and a gap at the front and back. A long oval head does the opposite: pressure on the forehead and the back of the skull, with gaps over the ears. Signs to watch for:

• Red marks on the forehead or temples after twenty minutes of wear.
• A hat that rocks side to side or front to back when you nod.
• A headache that starts in one spot rather than all the way around.

A hatter with a conformer can reshape the opening of a felt hat to match your head, and steam plus gentle hand pressure can ease a slightly tight spot. For a first purchase, though, buying the correct circumference matters far more than shape. Get the number right and most heads settle in fine.

When you fall between sizes

Plenty of people measure between two lines on the chart. Our general advice is to go up to the larger size, then snug it down. Here is why:

• A hat that is a little loose can be tightened with foam sizing tape tucked behind the sweatband. It is cheap, invisible, and easy to adjust.
• A hat that is too tight is hard to fix at home. Felt can be stretched a small amount by a hatter, but straw has very little give and can crack if forced.
• Leather sweatbands relax slightly with wear, but not enough to rescue a hat that squeezes on day one.

One exception: if your hair is very short and you plan to keep it that way, the smaller size can work, because there is nothing to compress under the band. If you grow your hair out or wear it up, choose the larger size.

Tip: try a new hat indoors on clean, dry hair, and keep the tags on until you are sure. We take returns within 30 days on unworn hats with tags, so a careful living-room fitting costs you nothing.

Youth sizing

Kids' heads change quickly, and fitted sizes rarely make sense for a hat that may only fit for a season or two. The youth hats we stock are sold as one size with a stretch sweatband. The Giddy Up Youth, for example, is 100% wool felt with a 4 inch brim, a 4 inch cattleman crown and a stretch band that flexes to fit a range of heads.

Measure your child the same way you would measure an adult, and keep the number handy. If a youth hat feels too loose, a strip of sizing tape behind the band helps. If your child has outgrown youth sizes and measures 21 1/8 inches or more, they can move into an adult fitted size at 6 3/4.

How a new hat should feel

A properly fitted cowboy hat sits level, roughly an inch or so above the eyebrows, with the sweatband touching evenly around the head. You should be able to slip one finger between the band and your forehead without forcing it. When you shake your head side to side, the hat should stay put.

It should not leave a deep red line after an hour. It should not sit on top of your head like a lid, and the brim should not rest on your ears. A brand-new leather sweatband can feel a touch firm at first, and that eases over the first several wears as it warms and shapes to you.

If something feels off, it usually comes down to one of three things: the wrong circumference, a head shape mismatch, or hair volume you did not account for. Remeasure first.
