Buying trousers online sounds simple until you have to choose between women’s trousers, men’s trousers, jogging bottoms, leggings, work trousers and sporty styles. A photo tells you little about the waistband, leg length or fabric. A low price doesn’t automatically mean they’ll be comfortable or long-lasting either.
Use this practical guide to start with how you’ll wear them, then check the size and material. That way, you’re less likely to end up with trousers that fit differently after a few washes, restrict your movement or aren’t suitable for the activity you bought them for.
An M or XL isn’t a standard size. Every manufacturer uses its own sizing guide. Some styles list the waist measurement in centimetres, while others use EU, UK or international sizing. So measure your waist and, where relevant, your hips and inside leg. Then compare your measurements with the product page.
For children’s trousers, age is only a guide. According to the product information, the Chicco leggings in size 104 are intended for children aged around 4 and list a waist measurement of 55 cm and a hip measurement of 62 cm, among other details. Always check the exact size chart before ordering.
Words such as “premium”, “performance” or “maximum comfort” can’t be verified on their own. Instead, look for details such as fabric composition, waistband type, pockets, fastening and fit.
Jogging bottoms made from 70% cotton and 30% polyester have a different fabric composition from track bottoms made from 100% polyester. Both can be practical, but for different situations. The product description and care label are your best guides; a brand’s claim about comfort or performance isn’t a guarantee for every wearer.
Soft jogging bottoms are handy for relaxing at home and in your free time, but they’re not always suitable for work that involves a lot of kneeling. Leggings can offer freedom of movement, but may not have pockets. Protective motorcycle trousers with hard armour also need to fit properly, and you should check that the protectors are correctly positioned.
So first decide what you need them for: everyday wear, sport, work, cycling, motorcycling or active children.
Pay attention to the combination of waist size, leg length and style. Slim fit sits differently from regular fit or wide-leg styles. An elasticated waistband with a drawstring gives you more room to adjust the fit, while a fixed waistband depends more on the stated size.
For men’s trousers and work trousers, sizing such as 32/32 or 32/34 matters: the first number usually refers to the waist and the second to the leg length. For international sizes, always check the chart for the specific product.
The fabric helps determine how trousers feel and how you should care for them.
Wash dark clothes according to the care label, and don’t use products on technical fabrics unless they’re recommended. Instructions can vary from one style to another.
Before you buy, check that the trousers have the features you need:
For motorcycle and protective trousers, also check which parts of the body are covered, how the protectors are secured and whether the trousers are designed to be worn under or over motorcycle clothing. The word “protective” doesn’t replace checking the product documentation or relevant safety information.

We’ve put together a complete, up-to-date list of products that meet these strict selection criteria and current European safety regulations.
Measure your waist where you’d normally wear the trousers and compare it with the size chart on the product page. For full-length trousers, measure your inside leg too. For women’s trousers, men’s trousers and children’s leggings, don’t rely on S, M or L alone, as sizes can vary between brands and styles.
Jogging bottoms, soft sweatpants, leggings and casual chinos are popular choices for everyday wear. Check the waistband, fabric composition and pockets. A style with a drawstring is handy if you want more room to adjust the fit. For a smarter look, black trousers or chinos may be more practical than track bottoms.
Follow the care label, wash dark colours separately and avoid bleach unless the label says it’s suitable. Don’t use unnecessarily high temperatures on stretch fabrics. Work trousers and protective trousers also need regular checks of the seams, pockets and protectors. This helps you spot when a part needs replacing.
