New Era Cap Differences: 59FIFTY, 9FIFTY, 9FORTY and More Explained

New Era caps differ across three components: brim, closure and crown shape. The model name mainly tells you how the brim and crown are built – closures can vary within a model depending on the version. A 59FIFTY comes in a fixed size and has a flat brim. A 9FIFTY is the adjustable version of that, usually as a snapback. A 9FORTY has a curved brim and an open, adjustable back.

That covers the core New Era cap differences. The finer details – crown height, fit and sizing system – then decide which model actually ends up on your head.

CapUniverse is a streetwear cap shop from Germany. New Era ranks #2 on our brand list – which makes it #1 among third-party brands.

New Era Cap Differences: Brim, Closure and Crown as Three Key Factors

Every New Era model can be classified by three components. Once you know them, you won't need a model list anymore.

Flat Brim or Curved Brim

A flat brim sticks out straight from the head. It has a stiff insert and holds its shape. A curved brim is pre-curved at the factory and sits more softly over the forehead.

Rule of thumb: 59FIFTY and 9FIFTY come flat, 9FORTY, 9TWENTY and 39THIRTY come curved. The 9SEVENTY sits in between – here it's worth checking the specific model. If you want to curve a flat brim, do it slowly over several days. One sudden bend is enough to crease the insert.

Fitted, Snapback, Strapback or Stretch

You can spot a fitted cap by the fact that it has no closure at all. It's bought in fixed sizes and fits equally snug all around. A snapback has a plastic strap with notches at the back – you'll hear the click when adjusting it.

A strapback closes with a fabric strap and a metal or plastic buckle. It sits flatter at the back than a snapback. Stretch-fit, on the other hand, has no adjustment at all: an elastic band pulls the cap together, and sizes run as ranges.

Structured or Unstructured Crown

The crown is the part that sits on your head. Structured means reinforced front panels – the cap can stand on its own on a table. Unstructured means soft fabric – the cap collapses on itself.

Both constructions usually have six panels and an inner sweatband. The difference is purely visual and about vibe. Structured looks bold and sharp, unstructured feels more relaxed.

New Era Cap Types at a Glance: 59FIFTY, 9FIFTY, 9FORTY, 39THIRTY, 9TWENTY, 9SEVENTY

These six model families cover almost our entire New Era range. The table sorts them by the three key factors.

59FIFTY: The Fitted with a Flat Brim

The 59FIFTY is the model worn by pros on the baseball field. It has no closure, but each cap comes in a fixed size. The crown stands high and structured, the brim is flat and stiff.

That's exactly why it's a permanent fixture in street style: it sits cleanly and doesn't slip. The catch: you need to know your size. Find more options in our 59FIFTY Caps and the full range of Fitted Caps.

9FIFTY: The Snapback with a Flat Brim

The 9FIFTY looks like a 59FIFTY from the front. At the back, instead of a fixed size, there's a plastic strap with notches. This means one model fits many head sizes, and you can pass it around your crew.

It's the cap for anyone who wants the flat brim without dealing with a size chart. Check out the 9FIFTY Caps or browse the whole range of Snapback Caps.

9FORTY: The Adjustable Strapback

The 9FORTY is our workhorse. Curved brim, structured crown, open adjustable back – simple as that. The closure varies by model: strap with buckle, snapback strap or velcro. It wears less noticeably than a 9FIFTY and fits almost any style.

The 9FORTY also comes in a junior version with a smaller crown. That one sells especially well for us: a Junior NY cap regularly ranks among the ten most popular individual products in our shop.

39THIRTY: The Stretch-Fit Between Fitted and Snapback

The 39THIRTY solves the fitted's sizing problem with an elastic band. There's no closure and no edge at the back of the neck. Sizes run as ranges, typically S/M, M/L and L/XL.

The brim is curved, the crown sits close to the head. That's why it's the first choice for sports and cycling. Nothing wobbles, nothing sticks out at the back.

9TWENTY and 9SEVENTY: The Soft and the Stretchy Route

The 9TWENTY is New Era's dad cap: unstructured crown, soft fabric, low-profile fit, open adjustable back. It collapses when you take it off – that's part of the look.

The 9SEVENTY blends two worlds. It combines a stretch-snap closure with a structured, slim crown – New Era itself describes it as a mix of the 9FIFTY and 9FORTY. The result: snapback looks with the feel of a stretch cap. Whether the brim is flat or slightly curved depends on the specific model.

59FIFTY vs. 9FIFTY vs. 9FORTY: The Direct Comparison

These three models sit side by side in almost every cart. The difference comes down to exactly two questions.

• Do you want a flat brim? Then stick with the 59FIFTY and 9FIFTY. The 9FORTY is out, since its brim is curved.
• Do you know your head size? If yes, go for the 59FIFTY – it fits most precisely. If not, go for the 9FIFTY.
• Do you want the cap to stay understated? Then the 9FORTY is your move. Curved brim, mid-height crown, adjustable back.

Unlike the 9FORTY, the 59FIFTY and 9FIFTY sit higher on the head. They visually lengthen the head and make the fit bolder. The 9FORTY blends into an outfit, while the other two make a statement.

The NY Baseball Cap: Which New Era Model Is Behind It?

The dark blue cap with the white NY logo isn't its own model line. NY is the New York Yankees' team logo, and New Era holds the MLB license for it. That's why the same logo appears on different models.

You'll find it most often on three families:

• 9FORTY NY: adjustable, curved brim – the easiest entry point.
• 39THIRTY NY: stretch-fit, close fit, no closure at the back.
• 59FIFTY NY: the fitted with a flat brim, the OG among NY caps.

We can see just how popular this is from our own bestseller list. A 39THIRTY NY cap ranks #2 among all individual products. Three NY caps in total appear in the top ten – no other design comes close.

Which New Era Model for Which Situation?

Construction is one thing, use case is another. This breakdown covers the most common cases.

• Everyday, uni, errands: 9FORTY. It handles rain, backpacks and hoods just fine and doesn't need to fit like a glove.
• Concerts, skateparks, street style: 9FIFTY or 59FIFTY. The flat brim is the whole point here.
• Running, cycling, gym: 39THIRTY. The closed back with a stretch band means nothing presses under your helmet.
• Summer, relaxed outfits: 9TWENTY. The unstructured crown folds up and fits in your pocket.
• Adjustable, but without pressure points on the neck: 9SEVENTY. The elastic band spreads out the tension.

Size and Fit: What Sets Fitted, Snapback and Stretch-Fit Apart

At New Era, the sizing logic is directly tied to the model. Three systems run in parallel.

• 59FIFTY: fixed sizes. Measure your head circumference in centimeters and match it against the size chart in the shop. The US size, like 7 3/8, is listed there as well.
• 9FIFTY, 9FORTY, 9TWENTY, 9SEVENTY: one size, adjustable. The range covers most head sizes.
• 39THIRTY: ranges like S/M or M/L. If you're between sizes, go for the larger range – the elastic band will adjust.

Measure your head circumference horizontally, just above your ears and a finger's width above your eyebrows. Don't pull the tape measure tight. A cap that already presses when you put it on will really press after three hours.

The Sticker on the Brim: Keep It On or Take It Off?

New New Era caps often come with a gold or holographic sticker on the brim. On fitted models, it also shows the size; otherwise it's a manufacturer authenticity mark, not a decorative element. Still, many people leave it on.

Both options are fine – it's a style choice, not a rule. We've broken down why the sticker became a style statement in the first place here: Why Do People Leave Stickers on Their Caps?

Frequently Asked Questions About New Era Cap Differences

What's the difference between the 59FIFTY and the 9FIFTY?

The 59FIFTY is a fitted cap: fixed size, no closure, flat brim. The 9FIFTY has the same flat brim, but closes with a snapback strap at the back. In short: same look up front, different fit at the back.

NY cap, New York cap, NY hat – is it all the same thing?

Yes. All three terms refer to the same cap: the white NY logo of the New York Yankees on a dark blue background. It's made by New Era, since the brand holds the MLB license. Only the underlying model differs – usually the 9FORTY, 39THIRTY or 59FIFTY.

Which New Era cap is adjustable?

The 9FIFTY, 9FORTY, 9TWENTY and 9SEVENTY are adjustable – depending on the model, via a snapback strap, buckle strap, velcro or stretch-snap. The 59FIFTY is not adjustable. The 39THIRTY has a closed back and adjusts via a stretch band, but runs in size ranges.

Can I bend the brim of a New Era cap?

Yes, on models with a flat brim – that is, the 59FIFTY and 9FIFTY. New Era explicitly states that both are designed to have a flat brim, but that it can be bent. Do it slowly, over several days. On the 9FORTY, 9TWENTY and 39THIRTY, the brim is curved at the factory and stays that way.

Which New Era model fits kids?

The junior versions of the 9FORTY. They have a smaller crown and the same adjustable back as the adult model.
