Imagine this: you’re traveling in China or browsing a Chinese online store, and you spot the perfect bra. But when you check the label, the size looks totally unfamiliar — numbers like 75B, 80C, or 85D. What do they mean? And how do they compare to your familiar US sizes like 34B or 36C?
Shopping for bras across countries can be confusing, especially because different regions use different sizing systems. In this guide, we’ll make it simple by giving you a US to China bra size conversion chart, a step-by-step measuring guide, and FAQs to make sure you get the perfect fit.
Why Bra Size Conversion Matters
Buying bras abroad or online is tricky if you don’t understand how sizes translate. A US 34B is not labeled the same in China — and cup letters can vary slightly in volume depending on the band measurement.
Without a conversion guide, you risk buying bras that feel too tight, too loose, or just plain uncomfortable.
How Bra Sizes Are Measured in the US vs. China
US System
- Band size: measured in inches (e.g., 32, 34, 36, 38).
- Cup size: letters (A, B, C, D, DD, etc.).
- Example: 34B → 34-inch band, B cup.
China System
- Band size: measured in centimeters (cm), based on the underbust.
- Cup size: also letters (A, B, C, D), but combined with band number.
- Example: 75B → 75 cm underbust (≈ US 34), B cup.
So, a US 34B usually equals China 75B.
