Why Brands Size Differently

Two shirts labeled "Large" from two different brands can differ by several inches. Here's why.

Different target bodies

Brands design around the body shape of their core customer base, which varies by brand identity, price point, and region.

Different fit philosophies

A streetwear brand designing for an oversized aesthetic will cut its "Medium" with far more room than a corporate formalwear brand cutting a slim, tailored "Medium."

Regional manufacturing standards

Sizing conventions that grew out of different regions — US, EU, UK, and various Asian markets — developed independently, which is exactly why cross-region conversion (like our Size Converter) is so commonly needed.

Fabric and cut choices

A stretch-cotton blend fits differently than a rigid, non-stretch weave, even at the same labeled size — stretch fabrics often run a size more forgiving than they appear on the chart.

The practical takeaway

Use general calculators and charts (like ours) to get in the right neighborhood, then check brand-specific reviews or charts for anything you're ordering online without trying on first.
