EUR Bra Size to US Size: How to Convert European Bras

Written by Carmen Rodriguez

Shopping for bras across borders can be exciting but confusing. International bra size conversion can be complicated due to differences between each country’s sizing system. European (EUR) bra sizing follows a different system than US sizing, especially when it comes to cup progression and band measurements. At Olivia Paisley Intimates, we believe that understanding size conversion, whether for Europe, the US, or any other country, is the key to finding true comfort and support, no matter where your bra is made.

This guide explains how EUR bra sizes convert to US sizes, with clear examples and expert tips. Taking exact measurements is crucial to ensure the correct fit when converting between systems. Measuring accurately is essential for finding your international bra size.

Key Differences Between EUR and US Bra Sizes

Band Size

EUR band sizes are based on centimeters (60–110). EU band sizes are determined by measuring the underbust in centimeters (cm) and rounding to the nearest 5cm.
US band sizes are based on inches (28–46). To convert a US band size to EU, you can roughly double the US number and subtract 40.

Cup Size

EUR sizing uses single-letter progression (D, E, F, G)
US sizing uses double letters (DD, DDD) after D

The cup labeling system is where most confusion happens.

Bra Cup and Bra Band Relationship

Understanding the relationship between bra cup size and bra band size is the foundation of finding your perfect fit, especially when navigating different bra sizes across countries. The cup size and band size work together to create the overall dimensions of a bra, and getting both right is key to comfort and support.

It’s important to know that the cup size is not a fixed measurement, it changes depending on the band size. For example, a 32B bra has a smaller cup volume than a 36B bra, even though both are labeled as “B” cups. This is because as the band size increases, the cup size must also increase to maintain the same proportion and fit. So, when you look at a bra size chart, you’ll notice that the cup size is always relative to the band size.

To determine your correct bra size, start by measuring your band size around your natural waistline, just under your bust, and your bust size at the fullest part. These two measurements will help you find your size on a bra size chart. Since European bra sizes are measured in centimeters and US and UK bra sizes are measured in inches, using a size conversion chart is essential when shopping for bras from different countries. For example, a UK 32B is equivalent to a European 70B, so always check the conversion chart to match your measurements to the correct size.

Keep in mind that different styles, like balconette, plunge, or sports bras, can fit differently, and sizing may vary between brands. Always refer to the brand’s specific size chart, as some European countries and manufacturers may have their own sizing standards. This is especially important when shopping online, where you can’t try on the bra before purchasing.

By understanding how the bra cup and bra band work together, and by using accurate measurements and a reliable size conversion chart, you can confidently shop for bras in US, UK, and European sizes. This ensures you find the correct size for your body, no matter the style or brand, and enjoy a comfortable fit that supports you throughout your day.

Why Converted Sizes May Fit Differently

Even when the size converts correctly:

EUR bras often have deeper cups
US bras may have wider underwires
Fabric stretch and construction vary by brand

Fit differences are about design philosophy, not incorrect sizing.

Tips for Buying European Bras in the US

✔ Always reference the brand’s conversion chart
✔ Check the brand’s FAQ or sizing page for detailed information
✔ Use the search function on the website to find the right size or style
✔ Use chat or contact the customer service team for personalized sizing advice
✔ Know your sister sizes in both systems
✔ Pay attention to cup depth and wire width
✔ Look for bra-sized swimwear for better support

EUR vs US Sizing: Which Is Better?

Neither is better, it’s about fit preference. European bras often focus on structured lift, while US bras prioritize comfort and accessibility.

EU band sizes increase in increments of 5 centimeters, while US band sizes increase by 2 inches. EU 60 = US 28, EU 65 = US 30, EU 70 = US 32, EU 75 = US 34, EU 80 = US 36, EU 85 = US 38, EU 90 = US 40, EU 95 = US 42. EU 70B is approximately equal to US 32B, EU 75C is approximately equal to US 34C, EU 80E is approximately equal to US 36DD/DDD, and EU 85G is approximately equal to US 38H or 38G in the UK/US. Check individual brand size charts for variations in cup sizes, especially with DD and DDD. US cup sizes include double letters (DD, DDD), while EU typically progresses from D to E without using the double letters. EU uses single-letter cup sizes (A, B, C, D, E, F, G, H) and does not generally use double letters like US sizes (DD, DDD). A US bra size 38DD is approximately equivalent to a European size 85E. European bra sizes are written differently than UK sizes, despite using the same measurements. The average American bra size is similar to the average European bra size, but the sizing systems are distinct.

Different countries, such as Australia and France, have their own bra sizing systems, so your preferred sizing may depend on the country of origin.

The best bra is the one that fits your body correctly.
