How International Clothing Sizes Work: A Simple US/UK/EU Guide for Online Shoppers
Understand how international clothing sizes work across US, UK and EU systems with simple measuring tips for online shoppers.
International clothing sizes can feel confusing because the same body measurement may appear as a US 8, UK 12 or EU 40. For online shopping, the safest method is to convert the label, then confirm measurements. Start with the Clothing Size Converter.
US, UK and EU Labels Use Different Numbers
Women's US and UK sizes usually have a consistent offset, while EU numbers use another scale entirely. Men's clothing may use chest, collar, waist, inseam or letter labels depending on the garment. This is why category-specific measurement matters more than memorizing one formula.
Measure Before You Convert
Take bust or chest, waist and hip measurements with a soft tape. For trousers, measure inseam and rise. For kids, use the Kids Size Converter because age, height and weight all affect size.
Use the Product Chart Last
A converter helps you understand the regional equivalent, but the product chart makes the final decision. Always check fabric stretch, cut and garment measurements. If your body measurements fall across two sizes, choose based on the area where fit matters most.
