How Garment Sizing Standards Differ by Region

Sizing standards vary meaningfully between regions, and a size L produced to one regional block can fit differently from a size L produced to another.

Manufacturing partners should be able to work from a buyer-supplied size chart, or provide documented sample measurements so buyers can confirm fit before bulk production.

For multi-market distributors, maintaining a single master size chart per product family — with clearly labelled measurement points — reduces returns and simplifies quality control across production runs.
