Levi's 501 men's jeans: how to choose the right fit, size and colour

The Levi's 501 men's jeans is instantly recognisable for its straight-leg cut and timeless American style. However, not all models bearing the 501 label offer the same fabric, the same comfort or the same sizing. A rushed purchase can leave you with a pair of trousers that are too stiff, too tight or simply not right for your everyday life.

Before you order, there are three pitfalls to avoid:

  • Confusing straight fit with slim fit: the 501 Original is generally worn at the waist, with a classic volume through the thigh and a straight leg. It's not the right choice if you're after the close-fitting silhouette of a Levi's 511 slim jean.
  • Underestimating the denim composition: a 100% cotton jean usually contains no elastane. It feels firmer and has a more structured drape, but it means you need to check the measurements carefully.
  • Relying only on your usual size: the equivalents between Levi's sizes, French sizes and centimetre measurements can vary depending on the fit and the reference. Always consult the size chart for the specific product.

What to check before you buy

1. The fit: 501 straight or 511 slim

The Levi's 501 Original has a straight-leg fit for men, sitting at the waist with a regular volume through the thighs. Its button fly and five-pocket design give it that classic look. It works just as well with trainers as it does with boots or smart-casual shoes.

The Levi's 511 men's jeans, on the other hand, is more fitted through the seat and thighs, with a slim leg. It's less close-fitting than a skinny jean, but the overall effect is noticeably more tapered. For daily commutes, busy days or simply for extra ease, a version containing elastane can be more comfortable.

2. The composition: cotton or stretch denim

It's worth looking at the composition in detail:

  • 100% cotton: on models described as 'non-stretch', the fabric doesn't give. The feel is firmer and the drape more structured.
  • 99% cotton, 1% elastane: this small amount adds welcome flexibility, as seen on several 511 models.
  • 94% cotton, 5% polyester, 1% elastane: this blend is used on some stretch 501s, keeping a straight fit while giving you more freedom of movement.
  • 89% cotton, 9% polyester, 2% elastane: used on certain 511s, this prioritises a softer, more stretchy fabric.

The term 'stretch' doesn't mean the jeans will be loose. It simply means the fabric moves better with you. On the flip side, even a stretch men's jean can lack support if you choose a size that's too big.

3. Colour and care

A dark blue Levi's jeans pairs easily with a light shirt, a grey jumper or a smart jacket. A black Levi's jeans fits better into an urban look and works well with both black shoes and contrasting styles. Medium wash and light wash shades, meanwhile, give a more relaxed feel.

To preserve the colour and the fit:

  1. Wash the jeans cold, inside out and with similar colours.
  2. Avoid bleach.
  3. Opt for a gentle tumble dry or hang the trousers up when the care label recommends it.
  4. Space out washes when the jeans aren't stained.

Some models recommend washing no more than once every ten wears to help extend their lifespan. This is a care guideline from the manufacturer, though, not a guarantee of how long the trousers will last.

Levi's size guide: the simple method

To avoid mistakes, measure your waist at the point where you'll wear the trousers, without pulling the tape tight. If you're between two sizes, also measure your hips.

On several 501 product pages, a Levi's size 32 corresponds to a waist measurement of around 81.3 cm and a hip measurement of around 97.8 cm. A Levi's size 34 is given as around 86.4 cm waist and 102.9 cm hips. These values should be checked on the page for the colour you've chosen, as some models have their own size chart.

For the length, consider both your height and the look you're after: a neat hem suits smarter outfits, while a little extra fabric gives a more relaxed feel. For the 511, length recommendations are usually given in inches and depend on your build.
