How to find your size across brands

A medium isn't a medium. When your cart spans four labels, one size never carries across all of them — here's how to get it right the first time and stop sending things back.

Why sizes don't match between brands

There's no enforced standard for clothing sizes. Each brand picks a “fit model” and grades the rest of the range around that body, so a label's medium encodes that brand's house silhouette as much as any measurement. Add vanity sizing, different target markets, and fabrics with different stretch, and the same number lands differently on every rack.

The fix isn't memorising a dozen size charts. It's knowing your own body measurements and reading each brand's chart against them — the number on the tag matters far less than the centimetres behind it.

Measure yourself once

Spend five minutes with a soft tape and you'll never guess again. Record four numbers and keep them in your notes:

  • Chest / bust — around the fullest part, tape level.
  • Waist — at your natural waist, roughly at the navel.
  • Hips — around the widest point, feet together.
  • Inseam — from crotch to ankle on trousers that already fit.

Match those to each brand's chart at checkout. When you fall between two sizes, size up for structured pieces and down for anything with stretch.

Brand-by-brand fit notes

UniqloCut for an East-Asian fit standard — tops and outerwear often run slim and a touch short; many shoppers size up one for a relaxed look.
H&MTrend-led cuts vary by collection and run small fairly often, especially fitted styles. Check the specific item rather than assuming your usual size.
ZaraEuropean sizing with a slim, structured silhouette; shoes in particular tend to run narrow and small — sizing up is common.
NikeFootwear often runs about a half-size small and narrow on performance models; apparel offers clear regular vs slim cuts.
AdidasShoes generally fit true-to-size with a roomier toe box on classic court styles; some running lines fit snug.
Levi'sDenim is sized by waist/inseam in inches; raw and shrink-to-fit styles change after washing, so follow the specific fit guidance.
ASOSHuge range and extended/“tall”/“petite” lines; fit varies a lot across its own labels, so lean on the per-product measurements.

Category-specific tips

Denim stretches with wear — buy snug at the waist for rigid styles. Knitwear relaxes, so avoid sizing up out of caution. Outerwear needs room for layers; check shoulder width first, since it's the hardest thing to alter. Shoes vary most between sportswear and fashion brands — read the length in centimetres, not just the EU number.

When in doubt

Check the product reviews for “runs small / large” patterns, favour the measurement chart over the size label, and lean on free returns for your first order from an unfamiliar brand. Once you've nailed your size with a label, it tends to hold across its range — so the work pays off every order after.
