If you have a smaller head, you know the routine. You cinch the strap of your cap down to its last notch and the fit still feels wrong. The problems are even worse with a fitted hat, most people buy the "average" size everyone recommends, and then when the cap ends up sliding down their head, they decide that maybe wearing hats isn't for them.
If this sounds familiar, then it doesn't mean that you have an awkward head. It means that you've purchased the wrong cap. The simple fact is that no matter how small or awkward you think your head might be, there's a fit that will be right for you, and you just need to know what works.
Why some caps don't fit smaller heads
"Standard" cap sizes miss for one reason: they are built to population averages. Popular adjustable straps or snap closure caps are too large for many people, simply because they are designed to cover the broad middle band of head sizes.
So if your head sits below that band, and you then choose to purchase an average size hat, you're picking the wrong size. Your fit will end up being at the looser end of a range built for someone else's head, which is exactly why many "adjustable" fits can still leave you with a slack fit.
Fitted caps work slightly differently. A closed-back style like the 59FIFTY® is built to an exact circumference rather than a range, so it should fit perfectly every time. The catch with this is that this only works if you buy the correct size from an actual head measurement, not a size guessed down from what you usually wear in another brand. The simple rule: get the measurement right and the fit follows.
How to measure your head correctly
No matter if you have a smaller head or a larger head, the solution depends on one number, so we will start there.
Measuring your head to get your cap size is easy, but many still don't do it. Simply wrap a soft tape measure around the widest part of your head, for most people this is roughly one finger-width above your eyebrows and just above your ears, making sure the tape measure is snug but not tight or uncomfortable.
This is your head's circumference and is the number that every New Era size chart is built from.
If you don't have a tape measure to hand, you can use a piece of string, mark where it meets, then hold it against a ruler. This should give you a rough idea, but won't always be 100% accurate.
We recommend taking the measurement two or three times and using the average, as this should give you a much better and consistent reading that is more likely to be accurate.
Then, if necessary, convert your measurements into either centimetres or inches and find your ideal hat size using our cap sizing guide.
Common fit problems, and why identical sizes can feel different
If you're measured up, but still having issues with your fit, then your problem may actually be telling you its cause. Most small-head fit complaints come down to a handful of causes, and knowing which one you have can point you straight to the right solution.
Sliding down
Gapping at the back
Sitting too high on the crown
Which features matter most for smaller heads
Before the styles themselves, three features decide whether a cap works on a smaller head, and none of them is the number on the label. Two caps in the same size can fit completely differently depending on these three things.

CLOSURE RANGE
The question is not whether a cap is adjustable, but how far it actually closes.
A snapback moves in fixed steps of roughly a centimetre, so a smaller head often lands between two notches: one setting too loose, the next too tight. A strapback, with its fabric slide, or a stretch-fit band adjusts smoothly rather than in jumps, so it can cinch well past the midpoint and stay there.
Look for a closure that still has travel left when it reaches your size, not one where you've already maxed out the range.
CROWN PROFILE
Profile is how tall the cap stands, and it is independent of your circumference. This is the main feature that most people overlook.
A tall, structured crown keeps its height whatever your head size, leaving empty space up top that makes a smaller head look like it has borrowed someone else's cap. A low, unstructured crown collapses gently onto the head and sits closer, framing the face instead of perching above it.
As a general rule, for smaller heads, lower almost always flatters more, even before you touch the closure.
CONSTRUCTION
The last feature to consider is the internal build of the hat. Many silhouettes come with a buckram-lined crown that holds a rigid shape, others have a stretch-fit band that contours to whatever it is pulled over.
In practice, that gives you two routes. A stretch-fit contours to a smaller circumference without needing an exact size, which is the forgiving option. A fitted cap is precise and holds beautifully, but only if you buy your measured size rather than guessing.
Which New Era styles are right for you
With the theory covered, here is the practical part. Match your situation to one of the six scenarios below.
You don't know your exact size
Start with the 9TWENTY®. Its strapback fabric slide has more travel than a snapback, so it cinches further down than most adjustable styles.
The low, unstructured crown sits naturally rather than perching high, which makes it the safest starting point when you have not measured yet. It is also the closest thing New Era makes to a relaxed dad cap, so it suits a smaller head and a casual look at once. Explore our 9TWENTY collection, or check the 9TWENTY size guide first.
You're between fitted sizes, or a little smaller than a stated size
Go for the 39THIRTY®. Its stretch-fit band contours to your head instead of relying on an external adjuster, so it can sit snugly a touch below its labelled size band without gapping.
This is the one for putting a cap on and forgetting about it, with no strap to dial in and no exact fitted size to commit to. The stretch-fit band runs unisex, so it answers smaller fits for men and women alike. Discover our 39THIRTY collection, or the 39THIRTY size guide.
You know your exact size and want the most precise fit
Choose the 59FIFTY®. Built to an exact size rather than a range, the closed back holds its shape rather than shifting as the day goes on.
This is the sharpest, most precise fit once you have measured accurately. Sizing down here means buying your correct measured size, not guessing smaller than usual. Explore our 59FIFTY collection.
You want a quick, everyday cap to snap on and go
Reach for the 9FIFTY®. As a snapback, it has multiple notches, though a shorter adjustment range than a strapback or a stretch-fit band.
In plain terms, it suits small-to-average heads rather than the very smallest, so if you are at the smaller end, treat this as a style to size carefully. It remains one of our most requested silhouettes, so it earns its place here with that caveat stated honestly. Browse our 9FIFTY collection, or the 9FIFTY size guide.
You're active or need something breathable
Look at a mesh-back 9FORTY®. It uses the same snapback closure, with the same shorter-range caveat, offset by a breathable mesh back and a pre-curved visor.
For warm-weather wear, running, golf or hiking, the adjustable range cinches enough for most smaller heads while keeping you cool. See our mesh cap collection or the wider trucker range.
Your head is smaller than standard adult sizing
Consider youth sizing. For anyone, adult or child, whose head sits below the smallest adult band, a youth cap is built to a genuinely smaller crown circumference rather than an adult size scaled down.
Frame this as the smart choice, not a compromise: a correctly sized youth cap fits better than an adult cap stretched to its smallest setting. Explore our kids' collection or the wider youth range.
Quick comparison
Here is the whole guide at a glance. Adjustability is how much a style can cinch down; precision fit is how exactly it holds once set.
| Style | Best for | Adjustability | Precision fit |
|---|---|---|---|
| 9TWENTY® | Unsure of your exact size | High | Low to medium |
| 39THIRTY® | Between fitted sizes | Medium (stretch band) | Medium to high |
| 59FIFTY® | You know your exact size | None, fixed size | Highest |
| 9FIFTY® | Quick, everyday wear | Medium (snap notches) | Medium |
| Mesh-back 9FORTY® | Active or warm-weather use | Medium (snap closure) | Medium |
| Youth sizing | Smaller than standard adult range | Varies by style | High, true small size |
Key takeaway
Getting the right cap for a smaller head is about matching the closure mechanism, and sometimes the size range itself, to your actual measurement, not just picking a style you like the look of.
Measure first, then match your situation to its solution, whether that is the adjustable travel of the 9TWENTY, the contouring stretch-fit of the 39THIRTY, the exact hold of the 59FIFTY, or a true youth size.
Measure up, then find your fit across our 9TWENTY, 39THIRTY and 59FIFTY collections.
