How to Buy a Hat as a Gift (Without Knowing His Size)

Buying a hat for somebody else feels like a trap. Get the size wrong and it perches on top of his head like a bottle cap, or it rides down to his eyebrows like he borrowed it from his big brother. Get the style wrong and it lives on a hook in the garage forever.

The good news: it's one of the easier gifts to get right, as long as you know a few tricks. Here's everything we know, with no guesswork left out.

Short Answer: The safest way to buy a hat as a gift when you don't know his size is to pick an adjustable hat, like a snapback or strapback trucker. A standard snapback fits heads from roughly 21¾ to 23½ inches around (hat sizes about 6⅞ through 7½), which covers most grown men. If you need an exact size for a fitted cap or a cowboy hat, read the size tag inside a hat he already wears, or measure his head and divide by pi. If you can't do either, a gift card lets him pick his own.

Why hats are tricky gifts (and why adjustable ones aren't)

Most clothes give you some wiggle room. A shirt one size too big still goes on. A hat doesn't work that way. Half an inch around the head is more than a full hat size, and a fitted cap or a felt cowboy hat that's off by one size is either a headache or a hat that blows off in the first stiff wind.

That's why adjustable hats are a gift-giver's best friend. A snapback has a plastic strap in the back with a row of snaps, usually seven positions. Each one moves the fit about three-eighths of an inch, so one hat covers a spread of about two inches. A strapback does the same job with a fabric or leather strap and a buckle or clasp, and it slides to any spot along the way. We went through every closure type in Snapback vs. Fitted vs. Strapback if you want the long version.

For scale: hat makers put the average grown man at about a 7⅜, roughly 23¼ inches around. That lands right in the middle of what a snapback covers. Unless the man you're buying for is known in the family for a big head, an adjustable trucker hat is going to fit him.

Six sneaky ways to find his hat size

If you've got your heart set on a fitted cap or a cowboy hat, you need a real number. Here's how to get one without blowing the surprise.

1. Read the tag in a hat he already owns

This is the easiest one. Most fitted caps print the size on a sticker under the bill or on a tag inside the sweatband, like 7¼ or 7⅜. Cowboy hats and dress hats usually have the size on a label or stamped on the inside of the sweatband. Wait until he's in the shower or out feeding stock, flip his favorite hat over, and take a picture of the tag.

2. Check which snap he's on

If all he wears are snapbacks, look at the back of his everyday hat. Snapped in the middle? He's an average head, and any standard snapback will fit him. On the tightest snap? He's on the small side. Hanging on by the last snap? He's on the big side, and you should measure before buying anything fitted.

3. Measure while he's asleep in the recliner

We're only half kidding. A head measurement takes five seconds: wrap a soft tape measure around his head about where a hat sits, across the middle of the forehead and just above the ears. No soft tape? Use a piece of string or a bootlace, pinch where it meets, and lay it against a ruler. You can also tell him it's for a craft project. People will believe almost anything about a craft project.

4. Do the pi trick

Here's a piece of hat trivia worth knowing. A U.S. hat size is just the head's circumference in inches divided by pi (3.14), rounded to the nearest eighth. A 22-inch head divided by 3.14 is right about 7, so that's a size 7. A 23¼-inch head works out to about 7.4, which rounds to a 7⅜. Once you have a measurement, you have a size. Our trucker hat sizing guide has a full chart if you'd rather not do the math.

5. Recruit an inside man

His barber, his brother, his wife, his hunting buddy, his mom. Somebody close to him either knows his size or can find out without raising suspicion. A buddy can take him into a feed store or western shop and get him to try a few on "just to see." It's an old trick from ring shopping, and it works on hats too.

6. Use your own head as a yardstick

If you've worn his hat around the house, you already know something. If his hat swims on you, he's bigger than you. If it pinches, he's smaller. Measure your own head and adjust from there. It's not exact, but it beats a blind guess.

Picking a style he'll actually wear

Size is only half the job. The other half is picking a hat that doesn't end up in a drawer. A few rules of thumb:

• Buy the hat he'd buy himself. Look at what's already on his hook. If he wears a mesh-back trucker every day, don't hand him a wool flat cap. Gifts that match his habits get worn.
• Match his colors. Black, tan and olive go with nearly everything a working man owns. Neon and novelty prints are a gamble.
• Mind the logo. Some men love a bold front, and some want a quiet patch. If his current hats are plain, go plain.
• Think about where he'll wear it. A hat for feeding cows in the rain wants to be tough. A hat for town on Saturday can be a little nicer. If you can find one that does both, even better.

If you're buying for someone who works outside, a waxed canvas trucker is a strong pick: the canvas sheds light weather and picks up character the more he wears it. If he's more of a classic black-hat guy, an embroidered trucker on a clean black crown never goes out of style.

Our honest recommendation

We'll tell you what we'd tell our own family. If you don't know his size, buy an adjustable hat. Every hat in our lineup is one-size adjustable, built from scratch in the USA, never an imported blank. You can pick from the black embroidered Trade Mark trucker or a waxed canvas trucker in Field Tan or Olive Drab, and all three were $38 when we checked in October 2026. Olive Drab is on pre-order as of this writing, so check the ship date on the product page if you're racing a birthday. You can see all of them in our American-made trucker hats collection.

And if a hat doesn't land the way you hoped? Our return policy gives 30 days after delivery to request an exchange on a hat that's unworn and still has its tags. Shipping both ways is on the buyer, so read the full policy at the bottom of any page before you count on it. Have him try it on indoors before he breaks it in.

When you just can't guess: the gift card

Some men are impossible. They have one hat they've worn for eleven years and they don't want another, or they're picky about the exact shade of tan. There's no shame in handing that fella a gift card and letting him choose.

Our Sackett Ranch digital gift card comes in amounts from $25 to $500. It's delivered by email, so you can print it out and tuck it in a card, or forward it on. It never expires and there are no fees to send it or spend it. Put it in an envelope with a note that says "Pick your hat," and you've given him the gift plus the fun of choosing.

A word about the gift itself

A hat is a funny kind of present. It's practical, and it's personal too. A man wears a good hat to work, to church, to the ballgame, to the funeral of an old friend. It soaks up sweat and sun and years. It ends up in the background of family photos. Years later somebody picks it up off a nail in the barn and says, "That was Dad's."

So don't overthink it. You don't need the perfect hat. You need one that fits well enough and looks like him. A gift picked with care has a way of turning into something he grabs on the way out the door every morning. That's a good thing to give somebody.
