Belts are worn for both function and style. A seemingly small accessory, they can have a surprisingly large impact on the impression you make. They can be a piece that pulls an outfit together, or end up becoming a distraction that sabotages its overall effect.

Unfortunately, many men don’t know anything about belts, besides the fact that they go around their waist.

So today we’ll talk about when to wear one, the different types, when to choose one kind over another, and how to buy a quality belt that fits you right.

This is a man’s complete guide to belts.

What Is a Belt?

Let’s start by defining what we’re talking about.

A belt is a cinching system that goes around the waist using tension to hold up a person’s pants. Even a piece of string can be a belt!

A belt can be used for carrying things. Look at Batman and his utility belt, or a gentleman who decides to conceal carry. However, most belts are purely decorative.

Simple. Now let’s start getting into more of the details of belts.

Anatomy of a Belt

The vast majority of belts (once you’ve moved beyond the simple string) have two parts: the buckle and the strap.

Many belts also have a keeper loop and/or an end tip (the end tip is usually metal, or leather on cloth belts). The end tip protects the end of the belt from being damaged/frayed and can make it easier to buckle. After the belt is buckled, the keeper loop stops the free end from flapping around.

In some belts, the strap and buckle are permanently joined together; in others, they can be taken apart and the buckle switched out. The part of the buckle that joins it to the strap is called the chape.

When Should You Wear a Belt?

In general, you should wear a belt with all pants (including jeans) that have belt loops. That’s what the loops are for! Leaving it off can look sloppy. Certainly with formal outfits, when your shirt is invariably tucked in, belts are essential. With more casual get-ups, when you’ll be wearing your shirt untucked, you can get away with skipping a belt, but you may still miss its functionality; remember that belts aren’t purely decorative — they help keep your pants up!

To maintain this function in the absence of a belt, you can choose suspenders as a stylish and fun alternative. Suspenders are a great way of dressing well for larger men — they’ll hold up your pants more effectively and reduce bulk at the waist. They also make a short guy look taller (or at least, they don’t make you look shorter by breaking the line of your body the way belts do.)

The one thing you don’t want to do is wear a belt and suspenders; it looks as if you either don’t know what you’re doing, or are just really, really worried about your pants falling down.

Formal vs. Casual Belts

Belts can roughly be sorted into two categories: formal and casual. Let’s dig into how these belts differ, and how to wear each type well.

Formal Belts

Formal belts don’t differ much from each other and share certain characteristics without many exceptions.

Buckle Type

Almost all formal belts include a frame-style style buckle, in which the strap goes through the frame. The prong of the buckle goes through holes in the strap to fasten the belt.

The buckle of a dress belt is usually shiny and sleek, gold or silver in color, and smaller and flatter than those found on casual belts.

Strap Width

A dress belt should be 1-1.5 inches wide, with thinner belts being more formal. A belt on the 1” end of things is suited for a smaller man, with a waist under 34”.

Strap Material

Leather is the only suitable material for dress belts (or a really good imitation leather if you’re vegetarian).

Cowhide. The most common leather used for belts, and comes in a few variations: full-grain leather is the best looking and most hardwearing, while calfskin is the softest and most supple. The highest quality formal belts will be full-grain calfskin.

Ostrich, lizard, crocodile, and alligator. These skins are all technically more casual belt materials, but can work as formal in a dark color.

Ostrich belts are a bold look, dotted with pockmarks from the feathers. They tend to fetch a high price.

Crocodile and alligator belts are even more upscale and have a subtler pattern and texture.

Faux leather is made with polyurethane on a fabric backing. It’s durable and low-maintenance, and the best faux leathers look realistic, although they don’t develop the same patina as real leather. Cheap fake leather looks, well, cheap and fake.

Strap Color/Pattern

A formal belt should be a subtle and understated addition to one’s outfit. Its surface should be solid and smooth, often with a sheen, and only have a subtle pattern at most. Black and brown are the most traditional colors for dress belts; some other colors you might see towards the smart-casual end of formal belts are oxblood, tan, navy, gray, and white for summer.

Matching a Formal Belt with Your Outfit

When you’re wearing a formal belt, be careful to match your leathers and match your metals: the strap of your belt should not only be the same color but also the same level of shininess as your shoes and other leather accessories, and the buckle should be the same color as your other metal jewelry and accessories (with the exception of your wedding ring, which can contrast with the other metals you wear).

Casual Belts

Casual belts come in many more types, styles, and colors than formal belts, and can be used to show more of your personality and individual style.

Buckle Types

Frame-Style

• Not only a buckle style for formal belts, the frame-style — usually with a bigger/thicker profile — can fasten casual belts as well

Plate-Style

• Usually detachable — paired with snap belts (straps without buckles)
• Plate is usually decorated — e.g., in cowboy and biker belts
• Hook goes through the front of the strap
• Throw (distance from chape to hook) adds to the length of your belt

Box-Frame

• Box is hollow, metal and open-ended
• Post presses the strap against the inside of the box
• No need for holes in the strap

O-Ring/D-Ring

• One or two rings form the buckle
• Belt is fastened by threading through them
• Casual, used with braided, webbing, and canvas belts

Snap

• “Male” and “female” ends snap together like a seat belt
• Very casual and functional, often used by those engaging in outdoor pursuits
• Not to be confused with snap belts

Micro-Adjust

• Uses a ratchet-style track system that requires a special type of strap
• A folding piece of metal presses the “teeth” of the track system into the strap
• No need for belt holes — allows minute adjustments

Strap Width

A casual belt will be 1.5-1.75 inches in width, with wider being more casual. A belt around 1.5” in width goes well with denim, chinos, and heavier fabrics. A belt wider than that is more unusual, suits jeans and casual trousers, and can be paired with classic and “statement” buckles.

Strap Materials

Leather

Full-grain leather. Broader, tougher, and stiffer than leather dress belts, leather casual work belts are usually made from the outer layers of a cow’s hide. Some even include marks from scars or brands that the cow acquired during its life.

Some leather belts are made with a snapped loop that can take different belt buckles, making it a customizable piece, and ideal for men who like to collect and show off different belt buckles. 

Braided leather. Used with a frame-style buckle to make very adjustable belts: you can put the prong in any hole in the braid. Braided belts are a good option when you want to keep things simple and unobtrusive; they add a little texture without making an overwhelming statement. They’re also easy to find, and often quite cheap.

More casual than a flat strip of leather, braided belts should not be worn with suits, but can work with a sports jacket.

Multicolored braided belts are even more casual, and are sometimes worn with summer ensembles for an east-coast prep look: khaki shorts, a light polo or button-fronted short-sleeved shirt, and boaters, with the bright belt holding down the center of the image.

Tooled leather. Decorated by “tooling,” a stamping process that leaves patterns on the leather, which are often then stained to make them stand out. Most are designed for interchangeable buckles.

Tooled belts work well with simple outfits, such as a pair of jeans and a basic button-down shirt. As they tend to be visually “busy” pieces on their own, the look starts to get overwhelming if you pair them with too many other patterned/textured items. 

Suede. Often used for casual belts, it’s less durable than full-grain leather, but usually has a full-grain leather backing for extra strength.

Other Materials

Leather-backed ribbon. A casual material that allows you to stand out with bright colors and bold motifs. These are usually paired with a frame buckle. Leatherback ribbon belts go perfectly with sailing, golf, and boat shoes.

Canvas. A staple of uniforms from the Army to the Boy Scouts, canvas belts with metal buckles are a plain, functional style. Most have a flat box buckle containing a sliding peg, which pins the strap in place at the desired position.

The most common styles of canvas belt are plain monochrome and monochrome with a single contrasting stripe running horizontally around the middle of the belt. Both have been in men’s casual wardrobes for the better part of a century.

Webbing. Another functional material, good for outdoor pursuits. It can be found in fun colors and patterns, and most often comes with a D-ring buckle.

Rope. Mostly a women’s fashion, but worn by men in nautical circles. Often fastened with a knot and loop rather than a buckle, they’re a bit preppy but durable and easy to clean, and can take a soaking better than leather.

Vinyl. Cheap, colorful, bold, and alternative. Vinyl belts are a young man’s style and can look tacky on older men. Really, outside maybe a concert, it can look tacky on a man of any age.

Strap Colors/Patterns

Brown is the most popular and versatile color for casual leather belts; black belts don’t pair well with jeans and khakis. With casual non-leather belts, colors can really run the gamut to every kind of pattern and hue.

Formal or Casual?

We can summarize the differences between formal and casual belts this way:

Formal:

• Smaller, sleeker buckle
• Thinner strap width
• Thinner, softer, sleeker, strap material, sometimes with a sheen
• Always leather

Casual:

• Larger buckle
• Broader strap width
• Tougher, thicker, stiffer, more rugged, often matte strap material
• May be leather, or different materials

Just as with shoes, there’s overlap between dress belts and casual belts. Dress belts are largely for wearing with suits and business attire, but can sometimes be paired with more formal sports jackets/ blazers and trousers. Conversely, casual belts are largely worn with jeans, khakis, and shorts, but can work with nicer chinos and more rugged sports coats.

But when an outfit clearly falls into one category or the other, you should choose the belt that best pairs with your clothes. If a dress belt is worn with casual pants, its proportions and materials will make it look too delicate, quite nerdy, and generally out of place. Conversely, wearing a casual belt with a suit will look jarring and throw off the formal effect you’re trying to evince. 

The Top 3 Go-To Belts for Men

If you’re having trouble deciding which belts to add to your wardrobe, we suggest these 3 as your basic essentials:

Dress belt — for business and evening wear

• 1-1.5-inch strap
• Only about 0.1 inch thick
• Black or brown leather
• Usually shiny
• Undecorated — maybe a little broguing or hand burnishing
• Small, plain, polished buckle — normally frame style
• Match leathers, match metals

Casual belt — for jeans/khakis

• 1.5-inch strap or wider
• Can be thicker than a dress belt
• Tan or natural leather
• Matte, rugged and can be braided, textured, or decorated
• Can have a larger and/or more decorative buckle — plate, box, or frame
• Doesn’t have to match leathers exactly (e.g. brown with tan, tan with white)

Webbed fabric belt — for summer casual

• 1.5-inch strap or wider
• Choose a strap color that goes with your wardrobe
• Strap can be patterned
• Usually has a double D-ring buckle
• Wear with chinos or shorts

How to Choose the Right Size Belt

Your belt size should be 1-2 inches longer than the size of your pants waist. So if you take a 40 in pants, you want a 41-42 inch belt.

Alternatively, you can work out the size of your new belt from your old belt. Measure from where you always buckle it to the opposite end of the strap, and get the closest size to that.

When buying a plate buckle, remember the throw (distance from chape to hook) adds to the length of your belt.

If you love a belt that’s the wrong size (or your size has changed since you bought the belt) DO NOT be tempted to gouge a hole in it with your pocket knife or kitchen scissors. It will be obvious, and the belt will end up breaking. Take it to your local cobbler to get a hole made properly.

Dress belts should only have a short tail end. You just want a few inches of leather to the left of the buckle when it’s fastened, long enough to tuck through the first belt loop or the loop on the belt itself if it has one.

Err on the side of shortness if you need to, rather than wrapping a long tail of leather around your hip a second time.

Casual belts can have a little bit more of a tail, although too long will still look awkward. Military-style canvas belts with brass buckles traditionally get their tails docked right down to the buckle.

How to Find a Quality Belt

Your casual belts can come and go, and you may actually like their being replaced every few years, so you can try some new styles. But with a more formal belt, you want something that you can use and enjoy for a long time. A quality belt can last for years if not decades, so it’s worth investing in a top-notch piece that looks good and wears well.

Very similar-looking belts sometimes vary widely in cost. The quality of the leather is one common factor: calfskin is the most common material used for belts, and a good belt will have a soft, supple leather. Flex the belt to make sure it hasn’t turned brittle or started to crack. Another good test of leather is to score the back very lightly with your fingernail — if a faint line appears, the leather is still soft and fresh. Old, hard leather will resist your nail.

Construction is the other major factor affecting the price of a belt. Look for small, tight stitching with no loose ends wherever the leather has been sewn. Buckles attached with a snap on the back of the belt can be changed out, while a buckle stitched in place is the only one you can wear with the belt; some men may find the flexibility of a snapped belt worth paying more for, especially in good leather. Belts can be custom-cut at some leather goods stores.

Brand names, in my opinion, are NOT worth paying more for when it comes to belts, because nobody’s likely to notice where your belt came from! If you’ve got a little extra to spend, invest in quality construction instead.
