How Do Trouser Sizes Work? A Guide for Tradespeople

If you’ve ever bought a new pair of workwear trousers only to find they’re too tight at the waist or too short in the leg, you’re not alone. Sizing can be confusing—especially when you're shopping online or choosing between different brands like Snickers, Blåkläder, and Portwest.

So, how do trouser sizes actually work? In this blog, we break it all down so you can find the perfect fit—first time.

Understanding Trouser Sizing: Waist x Leg

Most workwear trousers use the standard sizing format of “Waist x Leg”, measured in inches. For example, a size 34/32 means:

  • 34" waist (around the waistband)

  • 32" leg (inside leg length from crotch to ankle)

If you’re not sure of your size, grab a tape measure and measure:

  • Waist: Around your waist at the height where you normally wear your trousers

  • Inside leg: From the top of your inside leg (crotch) down to the ankle or where you want the trousers to end

Some brands—especially European ones like Snickers and Blåkläder—may also use EU sizes, but Tradeworx always provides conversion or UK sizing on product pages for convenience.

 

Different Fits for Different Jobs

Work trousers don’t just come in different sizes—they also come in different fits, which can affect how the trousers sit and how they perform on site.

  • Regular fit: Standard cut, suitable for most body types

  • Slim fit: Closer cut through the leg—offers a modern look without sacrificing movement

  • Stretch fit: Includes elastane or 4-way stretch panels for added flexibility

For example, the 6241 Snickers AllroundWork Stretch Trousers with Holster Pockets – Navy are designed with stretch fabric and a slim fit that moves with you—ideal for electricians, joiners or anyone up and down ladders all day.

 

Considering Length and Movement

Work trousers should allow for movement without riding up or dragging down. Too short? They’ll look awkward and could ride up when kneeling. Too long? They’ll bunch at the ankle and may drag on the ground—especially over work boots.

Some trousers come in short, regular, and long leg options, like the 1750 Blåkläder Craftsman Trousers with Stretch – Black. These are ideal if you need specific leg lengths and a custom fit, without compromising on comfort or knee protection.

 

What About Hi Vis Trousers?

Hi vis trousers follow the same sizing rules, but it’s even more important to get the right fit—especially if you’re pairing them with a hi vis jacket to meet Class 2 or Class 3 visibility requirements.

The Portwest PW242 Hi Vis Holster Trouser – Orange/Black is a great example. With a regular cut and ample pocket space, it suits most trades, and is available in a range of waist sizes to ensure a secure and comfortable fit.

 

Sizing Tips Before You Buy

  1. Measure first – Don’t guess; take a tape measure to your waist and inside leg.

  2. Check brand guides – Sizing can vary slightly between brands.

  3. Consider your work boots – Some prefer slightly longer leg lengths to sit well over boots.

  4. Account for movement – If you’re bending and crouching a lot, a stretch fabric or articulated knees are a smart choice.

  5. Read the product description – At Tradeworx, we highlight fit, fabric, and features to help you choose wisely.
