Whether you’re a man rocking a fitted running cap, a comfy beanie, or a classic fedora, there is one common denominator: A well-sized hat can take your look to the next level. But what are the components of determining hat size? When is it imperative to have a proper fit? Fret no longer, gentlemen, because after reading this guide, you will know the ins and outs of how to measure hat size like a professional, allowing you to wear your favorite hats and caps with confidence.

Step 1: Grab a tape measure

One of the basics you’re going to need is a tape measure to start measuring the circumference of your head. Begin by wrapping a flexible tape measure around your head, with actual tape measure approximately an inch above the eyebrows. Be sure the tape runs just above your ears and just below the bump that sits at the back of your skull. This is the spot that keeps your hats positioned just right.

If you are in a bind and don’t happen to have a tape measure around, be creative and use a piece of string and use the same steps, measuring the string against a ruler. To make the process as easy as possible, do the measuring in front of a mirror or ask a friend for a hand.

Step 2: Jot down your measurements

Once you’ve marked off your measurements, be sure to write them down in centimeters and inches because, depending on the brand, you might find the sizes only using the metric system or only the imperial. If you have both numbers on standby, you can save yourself a headache when shopping for the next hat to add to your collection. If you end up with a measurement that’s between sizes, always opt for the size up. It’s better to have more room than not enough, as a tight cap can be very uncomfortable.

Step 3: Understanding the one-size-fits-all system of measurement

Oftentimes, you are likely to see a hat labeled as “one size fits all.” This label generally applies to more relaxed styles of hats like beanies or hats with elastic bands designed to fit head circumferences within a certain range — usually between 54 and 61 centimeters. While these fit most men just fine, if you have a particularly small or large head, you may need to invest in a fitted version and avoid a potential fiasco.

While beanies are definitely more forgiving and versatile, adjustable styles like snapbacks or those with buckle closures offer a customizable fit that works for just about any head size. Learn how to wear a hat, have it sized properly, and then you will never be in doubt again.

Step 4: Adjusting for comfort

Some hat brands include cork bands that can go behind the inner band in order to make the fit even better. They aid in tightening or loosening caps to optimize comfort, so use them and adjust them until you find the best fit for your head. 

Why fit matters

A well-fitting cap goes beyond just about looking your best — it’s about feeling good as well. Whether you’re trekking on trails, lounging at a backyard BBQ, or just running around the city on errands, the perfect hat should be comfortable without squeezing your brain. So, gentlemen, grab your tape measure, find the correct size, and begin building a hat collection with confidence. Because at the end of the day, life is too short for ill-fitting hats!

The 5 suit brands you need to know to build your first suit wardrobe: Including the first aspirational one
Building a suit wardrobe starts with the brands you can trust
Men's Wearhouse Custom

Look, starting a wardrobe is difficult. You have to decide what kind of man you want to be. What kind of message do you want to send? What kind of budget do you want to use? And how often you want to go back to the drawing board. What kind of man do you want to be? Sounds heavy. Sounds dramatic. Maybe because, in some ways, it is. So much of what people initially believe about you remains in their subconscious long after they get to know you. So what you wear is important. The message you want to send is one of being put together, attentive to details, or it is the opposite. Laid back and unbothered. The budget is also integral to the wardrobe you build. High quality comes with high prices. However, it comes with longevity, so it means you don't have to replace it as often, saving money in the long run. So, what kind of man do you want to be? Hopefully one that wears men's suits.

No matter what man, message, budget, or shopping frequency you choose, a good suit wardrobe will need to be a part of it. So, where do you go? How do you start? Here are the five brands to trust to get started. No Tom Ford, Brioni, giant fashion houses here. These are the five suits for the man starting out. And one for the man aspiring to the next step. The first four, you can grab your first quality suit for around the $1,000 mark. The aspirational one will be your first custom, so it will be a bit more.

Longines refreshes its cult-favorite central power reserve in light blue
The Swiss watch company is giving the Conquest Heritage Central Power Reserve some new dial and bracelet options.
Wristwatch, Arm, Dial

Longines has been around since 1832, which makes it one of the oldest continuously operating watchmakers on Earth — old enough to have spent decades strapped to the wrists of aviators and explorers before most brands existed. So when the Saint-Imier company, now part of the Swiss giant Swatch Group, revives something from its own archives, it's got real history to draw on. The Conquest Heritage Central Power Reserve is a good example.

The Conquest line dates to 1954 — the first Longines collection to have its name trademarked with the Swiss IP office. And in 1959, one Conquest model introduced the complication this watch is built around: a power reserve indicator planted dead center on the dial. For 2026, Longines has given the modern revival a light refresh: a new light-blue opaline dial and (for the first time on this model) a stainless-steel bracelet alongside the returning dark leather strap.

Shohei Ohtani’s newest Seiko is out of this world
Seiko built Shohei Ohtani a one-of-one watch that tracks a million hours across five rotating discs — and you can't buy it.
Wristwatch, Arm, Body Part

The Seiko Star Time, presented to Shohei Ohtani on July 3, marks his tenth year as a Seiko ambassador. It's not for sale, will never be for sale, and there's exactly one on Earth — currently strapped to the best baseball player alive. Oh, and also? It looks absolutely nuts. Instead of hands, the Star Time tells time with five stacked, concentric discs, each tracking a different scale of accumulated time: 24 hours, then 1,000, 10,000, 100,000, and finally a disc that runs all the way to one million hours.

That's roughly 114 years — a full human lifetime, give or take. The discs turn continuously, so slowly you can't see them move. Seiko named it "Star Time" for exactly that reason: like stars drifting across the sky, the motion is imperceptible in the moment but relentless. A little existential for a watch company, but let's go with it.
