Buying belts: how to choose the right belt for every outfit and occasion

A belt may seem like a simple clothing accessory, but you quickly notice when you choose the wrong one. A belt can be too short, fail to fit through the belt loops properly or lose its shape after just a few months. So if you want to buy belts, it is worth looking beyond colour or brand.

Three common pitfalls are:

• The size is interpreted incorrectly. A size 85 does not refer to exactly the same waist measurement for every brand. Sometimes it indicates the distance from the buckle to the middle hole, while in other cases it refers to a different product measurement.
• The material is made to sound better than it is. “Leather look” usually means a faux leather belt rather than genuine leather. That does not necessarily make it a poor choice, but the properties and lifespan are different.
• A universal belt does not automatically suit every outfit. A wide canvas belt works particularly well with jeans and casual clothing. With a suit, a narrower belt and a more understated buckle are usually more practical.

What should you consider before buying a belt?

1. Choose the material based on how you will use it

A leather belt generally has a classic look and works well with jeans, chinos and formal clothing. However, check that the product description specifically states “100% leather” or “genuine leather”. For example, the Calvin Klein Formal Plaque Belt lists 100% leather as its main material. The Calvin Klein Leather Logo Belt also states genuine leather.

A faux leather belt is often made from polyurethane. This material can be suitable for everyday use and is usually easy to clean, but it has different properties from leather. The black Urban Classics belt in the product selection is made from 100% polyurethane.

A canvas belt is lightweight, flexible and suitable for casual outfits. According to the product details, the Canvas Belt Black One Size is made from 100% polyester and has a 120 cm adjustable strap. A canvas belt works well with jeans, shorts and leisurewear, but is less suitable for formal trousers.

A standard trouser belt is not designed for strength training. A weightlifting belt, gym belt or powerlifting belt has a much more rigid construction. Only use this type of belt according to the product instructions, and never as a substitute for proper technique.

2. Check the width, buckle and belt loops

Measure the width of your trousers’ belt loops before choosing a model. A wide training belt will not fit through the standard loops on a pair of suit trousers. For formal clothing, a belt around 3 to 3.5 cm wide is often a practical choice. The Calvin Klein Formal Plaque Belt is 3.5 cm wide.

Also consider the buckle. A large branded buckle is more eye-catching and is best suited to casual clothing. A matt or brushed-metal buckle looks more understated with businesswear. A black belt with a simple buckle is therefore highly versatile, while a prominent logo becomes more of a feature of the outfit.

3. Measure your waist in the right place

Use a flexible tape measure to measure where you actually wear the belt. Do not pull the tape too tightly. Then check the size chart for the specific product.

For example, the Calvin Klein Leather Logo Belt lists size 85 in relation to EU size 38 and a particular waist measurement range. The formal Calvin Klein belt uses a different chart. Do not compare sizes between brands without checking the details.

An adjustable belt or one-size model can be useful if you fall between two sizes. The Canvas Belt Black One Size has a continuously adjustable strap. With a fixed size, such as the Urban Classics belt in M, L or XL, it is important to measure your waist beforehand. Bear in mind that the buckle may not be included in the total length.

Care for a longer lifespan

The right care depends on the material:

• Leather: always follow the care label. Avoid prolonged contact with water and allow the belt to dry at room temperature.
• Canvas: not every model can be washed. For the Canvas Belt Black One Size, cleaning with a soft, damp cloth is recommended.
• Faux leather belt: check whether machine washing is permitted. The Urban Classics models state that they can be washed on a cold, delicate cycle, but should not be tumble-dried.
• Training belt: wipe the belt after use, allow it to air-dry and check the stitching, buckle and closure before every training session. According to the safety information, the Thor Athletics belt is not a tool for preventing injuries caused by incorrect lifting technique.

A Levi’s belt from the Athena Collection is another casual option. According to the product details, this unisex belt is made from 69% cotton and 31% hemp. When choosing between sizes such as 70, 80, 85, 90 and 95, pay close attention to the selected variant.

Frequently asked questions about buying belts

How do I determine the right belt size?

Measure your waist where you wear the belt and compare it with the size chart on the product page. Do not look only at your trouser size. For some brands, the belt size is based on the distance to the middle hole, while other models list the total length.

Is a black belt suitable for formal clothing?

A narrow black belt with a simple metal buckle often works well with a suit or smart trousers. Check that the colour of the buckle matches other metal details, such as a watch or cufflinks. A wide buckle or prominent logo is more likely to work as part of a casual outfit.

When do I need a gym belt or powerlifting belt?

A gym belt or powerlifting belt is designed for specific strength-training exercises, not everyday use. Only choose one when its width, thickness and closure are suitable for your training. Follow the manufacturer's safety and care instructions, and continue to focus on performing the exercises correctly.
