How size conversion works

A converter estimates the closest equivalent between sizing systems using known size relationships or body measurements. Measurements are usually the better reference point, but brand charts should still be checked before buying.

Why sizing varies by brand and region

Even within one system, brands cut differently and numbered sizes have drifted over time. Treat the converted size as your starting point, then confirm against the brand’s own chart before buying. More on why brand sizes differ.
