Hands measuring head circumference with tape measure

Cowboy hat size guide: measure right, fit first

Measure your head with a flexible tape just above your eyebrows and ears, then match the centimetre result to the conversion chart in Section 3. That single step prevents most sizing mistakes. A cowboy hat should sit roughly one finger above your brows, not resting directly on them or floating too far above.

Quick steps before you read further:

  • Wrap a flexible tape around your head, about 1 cm above your eyebrows and ears.
  • Read the measurement in centimetres (more precise than inches for online orders).
  • Match that number to the chart below to find your US numeric size and NZ/AU label.
  • If you land between two sizes, choose the larger size.

Pro Tip: Write your centimetre measurement down now. You’ll use it every time you buy a hat online.

Key takeaways

Measure your head in centimetres above your brows and ears, match the result to the conversion chart, and round up when you’re between sizes.

Point Details
Where to measure Place the tape 1 cm above your eyebrows and ears; keep it level and snug.
Round up between sizes When your measurement falls between two sizes, always choose the larger one.
Material affects fit Felt eases with wear; straw and leather stretch very little, so size true or up.
Adjust a loose hat Use hat sizing tape or sweatband inserts; stretching a tight hat has limited results.

How do you measure your head for a cowboy hat size guide?

Getting an accurate measurement takes two minutes. Justin Boots recommends measuring above the brows and ears, keeping the tape level, and repeating for accuracy.

  1. Grab a flexible tape measure. A dressmaker’s tape works best.
  2. Position the tape about 1 cm above your eyebrows and just above the tops of your ears. This is where the hat will actually sit.
  3. Keep it level. The tape should run parallel to the floor all the way around.
  4. Snug, not tight. You want contact with the skin, not compression.
  5. Measure twice. Write down both readings and use the larger one.
  6. No flexible tape? Use a piece of string instead. Wrap it around your head at the same position, mark where it meets, then lay it flat against a ruler. This string method gives a reliable result when you don’t have a tape on hand.

Measurement checklist before you convert:

  • Hair tied low or flat (bulky buns add false centimetres).
  • Tape sits level all the way around.
  • You have two consistent readings within 0.5 cm of each other.

Pro Tip: Centimetres give you finer precision than inches for online purchases. HatWanderer confirms that centimetre measurements minimise rounding error — always record both cm and your fractional US size.

Cowboy hat size chart: centimetres to US sizes and NZ/AU labels

Hat sizes increase in 1/8-inch increments, so a single centimetre can shift you across two size steps. Use the table below to convert your measurement directly.

Head circumference (cm) Head circumference (inches) US hat size NZ/AU generic size
— 20 7/8 6 5/8–6 3/4 XS
— 21 1/2 6 7/8–7 S
— 22 1/2 7–7 1/8 M
— 22 5/8 7 1/4–7 3/8 L
— 23 1/4 7 1/2–7 5/8 XL
60.5 23 7/8 7 3/4–7 7/8 XXL

As a reference point, a mid-range head circumference converts to a common US numeric size. JK Western’s sizing guide recommends choosing the larger size when your measurement falls between two options — a rule worth following for online orders where you can’t try before you buy.

A few notes on using this chart:

  • Felt hats and straw hats can feel different at the same numeric size (more on that below).
  • Brand sweatband depth varies, so always cross-check the product’s own size notes.
  • Women’s and youth sizing follows the same centimetre conversion — the labels differ by brand, but the head circumference numbers don’t change.

How should a cowboy hat fit, and what if it’s not quite right?

A correctly fitted cowboy hat sits about one finger’s width above your eyebrows, stays put when you bend forward, and leaves no deep pressure marks after 15–20 minutes of wear. Those three checks tell you more than the label ever will.

Signs the fit is off:

  • Too tight: Leaves a red ring, causes a headache, or feels like it’s gripping your temples.
  • Too loose: Shifts when you move, tips forward in a breeze, or spins on your head.

Practical adjustments when the size isn’t perfect:

  • Loose hat: Add hat sizing tape (foam or cotton strips) inside the sweatband. Sweatband inserts work the same way and are easy to remove.
  • Tight hat: Options are limited. A hatter can stretch a felt hat slightly, but straw and leather respond poorly to stretching. Sizing up is usually the better call.

Pro Tip: For felt hats, a slightly snug fit at purchase is fine — felt conforms with wear. For straw or leather, buy true to size or one step up.

Does hat material change which size you should pick?

Yes, and it’s one of the most overlooked parts of cowboy hat sizing. Felt hats tend to feel snug initially but conform with wear, so a firm fit at purchase often relaxes into a comfortable one after a few wears. Straw hats stretch very little, so a hat that feels tight in the shop will still feel tight in six months.

Leather sits somewhere in between — it can soften slightly with heat and wear, but it won’t reshape itself the way wool felt does. Crown height also plays a role. A taller cattleman crown sits higher on the head and can feel looser around the temples than a lower-profile crown at the same numeric size. If your head runs oval rather than round, check whether the brand offers oval-shaped crowns — a round-shaped hat on an oval head creates pressure points regardless of the size number.

Simple rules by material:

  • Wool felt: A slightly snug fit is acceptable. It will ease.
  • Straw: Buy true to size or round up. No meaningful stretch.
  • Leather: True to size. Check crown shaping against your head profile.

Urbancaps sizing support for NZ customers

Urbancaps ships from New Zealand stock, so there’s no waiting on international freight. The Urbancaps hat specialists can help with sizing questions before you order — check the product pages for specific size notes, or reach out via the site’s support channel.

Three wool cowboy hats worth measuring up for:

  • Premium Wool Cowboy Hat (Western Felt Cattleman Hat): Available in larger sizes including XL (60–61 cm). Good for customers who consistently measure at the top of the standard range.
  • Denton Premium Wool Cowboy Hat (Adjustable Western Felt Hat with Leather Band): The adjustable fit makes this one forgiving if you land between sizes.
  • Mulholland Wool Cowboy Hat (Classic Western Wide Brim Hat): A traditional shape in NZ stock for shoppers after a wide-brim silhouette.

Before you order, run through this checklist:

  • Measure your head in centimetres and confirm against the chart above.
  • Read the product-specific size notes on the product page.
  • Check Urbancaps’ returns and exchange window in case the fit needs swapping.
  • If you’re between sizes, order the larger one.

What experienced hat buyers do differently

Most sizing problems come down to two habits: measuring over a thick bun or ponytail, and trusting a generic S/M/L label without checking the centimetre range behind it. Generic labels vary more than people expect — one brand’s L starts at 58 cm, another’s at 59 cm. That single centimetre is the difference between a hat that fits and one that spins.

The habit that prevents returns is simple: measure in centimetres, write the number down, and keep it somewhere you’ll find it next time. Experienced hat buyers treat their head circumference the same way they treat their shoe size — it’s a number they know off the top of their head (so to speak) and use every time they shop online. For a complete wool hat sizing reference, Urbancaps has a dedicated guide that covers the same principles for wool styles specifically.

FAQ

How do I know what size cowboy hat to get?

Measure your head circumference in centimetres about 1 cm above your eyebrows and ears, then match that number to a conversion chart to find your US numeric size and NZ/AU label. If you fall between two sizes, choose the larger one.

Is a 7 3/4 hat size considered large?

Yes — US size 7 3/4 corresponds to roughly 60.5–61 cm and sits in the XXL range on most NZ/AU size charts. It’s at the upper end of standard sizing, which is why Urbancaps stocks the Premium Wool Cowboy Hat specifically in XL (60–61 cm).

Is a cowboy hat size the same as a fitted cap size?

The numeric sizing system is the same — both use fractional US sizes based on head circumference — but cowboy hats often have deeper sweatbands and shaped crowns that can make the same number feel different. Always check the brand’s specific size notes rather than assuming a direct transfer.

What is the cowboy hat rule about fit?

A properly fitted cowboy hat sits about one finger above your eyebrows, stays in place when you bend forward, and leaves no deep pressure marks after 15–20 minutes. Those three checks are the practical standard for a correct fit.
