US to EU Clothing Size Conversion Chart

Women's clothing sizes differ significantly between US and EU systems. US women's sizes use even numbers (0, 2, 4, 6, etc.), while EU sizes use a different numbering system based on body measurements in centimeters. The EU system generally adds 30 to the US size number, though this is an approximation and the precise relationship varies by garment type.

The following conversion table covers standard women's apparel including dresses, blouses, jackets, and outerwear. For pants, skirts, and bottoms, the same size conversions generally apply, though hip and waist measurements should be cross-referenced for accuracy.

Men's clothing size conversions between the US and EU depend on the garment category. For suits and blazers, US sizing uses chest measurements in inches, while EU sizing uses a different numerical system. For shirts, US sizes are based on neck measurement in inches, while EU shirts use centimeter-based measurements.

For men's suits and blazers, the EU size is generally the US size plus 10. For dress shirts, the EU size corresponds directly to the neck measurement in centimeters.

Children's clothing in the US uses age-based sizing (2T, 3T, 4, 5, etc.), while EU children's sizing is based on the child's height in centimeters. This height-based system is more consistent across brands since it references a measurable body dimension rather than an age range that can vary significantly.

The following conversions provide general guidance. Because children's growth patterns vary, always cross-reference with the height and weight measurements provided by the specific brand.

The fundamental difference between US and EU sizing systems lies in their reference points. US sizing evolved as a vanity-based system where the size number does not directly correspond to any body measurement. EU sizing is more metric-oriented, with size numbers often deriving from body measurements in centimeters (height for children, bust-based derivations for women).

This difference means that conversions are not perfectly precise — a US 8 from one brand may not correspond exactly to an EU 38 from another. For fashion professionals creating products for both markets, the most reliable approach is to define your size range using actual body measurements in both inches and centimeters, then assign the appropriate US and EU size labels based on those measurements.

Creating detailed measurement charts with both imperial and metric values for every size in your range eliminates conversion confusion for manufacturers and customers. The Skema3D measurement chart template supports dual-unit measurement specifications for exactly this purpose.

When designing for international markets, build your size chart from body measurements rather than converting between size systems after the fact. Start with your target measurements in centimeters (the more universal standard in fashion production), then assign both US and EU size labels based on where each size falls in the respective system.

Always include a detailed size guide on your e-commerce product pages that shows actual body measurements for each size. This reduces returns caused by sizing confusion and builds customer confidence in purchasing. Skema3D's integration with Shopify supports including measurement-based size guides alongside product listings.
