Band and cup references by region

International Bra Size Charts by Region for Europe, North America and Asia-Pacific

Compare common regional labels without scanning one extra-wide global table. Every conversion remains a starting point because brands can grade bands and cups differently.

Regional Bra Size Conversion Tables for International Online Shopping

Start with the table for the retailer's market, then compare the full band-and-cup label. A cup letter alone is not a fixed volume, and the same country can contain several brand-specific sequences.

Specialist Polish brands

Comexim and Ewa Michalak Polish Bra Size Guide

These are brand systems, not a single Polish national standard. Use the labels below to understand their structure, then confirm measurements with the retailer's own calculator or size table.

How Comexim and Ewa Michalak bra size labels are structured
Brand systemCommon bandsCup sequence exampleConversion boundary
Comexim60, 65, 70, 75...B, C, D, E, F, G, H, HH, J...Brand chart uses approximately 2 cm cup intervals; treat conversion as a starting point.
Ewa Michalak60, 65, 70, 75...AA, A, B, C, D, DD, E, F, FF...Proprietary sizing; the brand states that it is not a 1:1 EU, US, French or UK conversion.

The interactive converter provides approximate starting labels. Ewa Michalak explicitly describes its sizing as proprietary and not directly equivalent to EU, US, French or UK sizing.

How to Use an International Bra Size Chart Without Losing Cup Volume

Always convert the complete size. For a specific starting label, use the interactive bra size converter. China, South Korea and India are not presented as direct conversions because local retailers may use metric, international or proprietary labels under the same market name.
