Ordering a new pair of trousers online might seem straightforward, but a product photo doesn't tell you everything. A fit can turn out slimmer than expected, a fabric can feel warmer or thinner than you imagined, and international sizing can cause confusion. So if you're searching for trousers for women and men, it's worth checking the intended use, the size and the material first.
From a comfortable jogging bottoms or sweatpants to a women's jeans, chinos, cargo trousers or sporty track pants: the right choice depends on where and how you plan to wear them.
A size M or XL isn't the same across every brand. Even within one brand, a slim fit, regular fit and wide leg trouser can fit differently. Always check the waist measurement in centimetres and compare it with a pair of trousers you already find comfortable.
What's more, some models list multiple sizing systems, such as EU, UK, US and international sizes. Look at the size guide for the specific product, not just your usual size.
"Cotton" doesn't automatically mean a trouser is light and flexible. A pair of jeans made from 100% cotton can, for example, have less stretch. A cotton-polyester blend can feel softer or be easier to care for. Polyester can be practical for sportswear, but it feels different from fleece or denim.
So pay attention to:
A slim fit men's trouser offers a close-fitting silhouette, while a regular fit or straight leg gives more room. A high-waisted trouser sits higher on the waist; a mid-rise model sits lower. For sport and relaxation, an elasticated waistband and drawcord are often more practical than a fixed waist with a button closure.
Measure your waist around the point where the trousers should sit. With jeans, two numbers are common: the waist size and the inside leg length, for example 30/30. Also check whether the sizing is given in centimetres, EU sizes or international letters.
Pay attention to the style too:
A women's jeans or blue jeans made from 100% cotton typically has no elastic fibre according to the product specification. That can suit someone looking for a classic denim structure, but check the waist and hip measurements extra carefully.
For jogging bottoms, sweatpants or an adidas trouser, you'll often see a cotton blend. The Adidas Trefoil Essentials Pants IY7361 consists, according to the product information, of 70% cotton and 30% recycled polyester fleece. The elasticated waistband with drawcord makes the fit adjustable. The ribbed cuffs keep the trousers closer to the ankle.
A track pant from Urban Classics is, according to the product information, made from 100% polyester. That material, the straight leg and the elasticated waist suit casual use, walking or light sporting activities. The product specification does not mention any stretch; bear that in mind if you need plenty of room to move.
Check before buying whether the trousers can go in the washing machine and whether the tumble dryer is not recommended. The Adidas trousers must be washed cold on a delicate cycle and, according to the given instructions, should not be tumble dried. The Levi's 501 is also washed cold; the product information additionally states that washing inside out with similar colours is recommended.
A pair of trousers you wear often therefore needs not only the right look, but also a care routine that fits your household.

Measure your waist and, for jeans or long trousers, also your inside leg length. Compare these values with the size guide on the product page. For a style without stretch, an accurate waist measurement is especially important. Also pay attention to the fit: a slim fit differs from a regular or wide leg trouser.
The terms are partly used interchangeably in online shops. Jogging bottoms or sweatpants usually refer to a casual trouser with an elasticated waist, often made from cotton or a cotton blend. Track pants are more often made from polyester and have a sportier cut, cuffs or side panels. Always check the specific material and fit information.
Follow the care label, wash dark colours separately and don't use bleach when it's not recommended. Turn jeans inside out and avoid washing them unnecessarily often. Let fleece or cotton-blend trousers air dry if the product instructions advise against tumble drying. That way, you tailor the care to the fabric rather than just the appearance.
