EU Bra Size to US Size: Your Essential Conversion Resource

Shopping for bras across borders can be bewildering, especially with differing sizing systems. The European (EU) and U.S. bra sizes use distinct cup labeling, often leading to errors in size selection. Understanding these conversions is crucial for achieving optimal comfort and support.

Learning how to convert bra sizes can feel daunting since the EU and U.S. systems are distinct and utilize different measurement standards. European sizes are based on centimeters, while U.S. sizes rely on inches.

This article clarifies how EU bra sizes translate to U.S. sizes, complete with examples for easy understanding.

Primary Differences Between EU and US Bra Sizes

EU and U.S. bra sizing systems are independent and require unique approaches. The band size in EU measurements is in centimeters, contrasting with inches for U.S. sizing. The most significant difference, however, lies in the cup size lettering.

In EU sizing, the band sizes increase by increments of 5 centimeters: for instance, 70, 75, 80. An EU E cup generally aligns with a U.S. DD cup, while an EU F cup typically matches a U.S. DDD cup. EU 70 converts to U.S. 32, EU 75 to U.S. 34, EU 80 to U.S. 36, EU 85 to U.S. 38, and EU 90 to U.S. 40. Some modern brands even provide a size conversion chart on the tag, featuring FR, EU, and U.S. sizes side by side. An EU size 75 is equivalent to both a UK size 34 and a U.S. size 34. EU band sizes reflect the actual underbust measurement in centimeters, while U.S. band sizes usually add 4–5 inches to the actual rib cage measurement.

Many retailers lack side support bras for plus-size women, resulting in numerous women wearing incorrect sizes. While the average sizes in the U.S. and Europe are similar, their charts indicate different dimensions. Bra size equivalents vary across brands, making it essential to verify if you're uncertain. Fortunately, international shipping allows for global bra shopping, no matter your location.

This discrepancy complicates the process of finding the right fit, as the systems aren't interchangeable and necessitate separate understanding of each.

Band Size

Accurate band measurements in centimeters (cm) are vital for a proper fit when converting EU sizes to U.S. sizes.

Cup Size

• U.S. sizing employs double letters (DD, DDD)

• EU sizing utilizes single letters (D, E, F, G)

When converting EU to U.S. bra sizes, cup size equivalents can differ, so it's crucial to select the right cup volume for your body to ensure the best fit.

How to Measure for the Right Fit

Finding the correct bra size is essential for comfort, support, and confidence, regardless of the sizing system you encounter. Since sizes can vary across countries, brands, and styles, accurate measurements are the best way to guarantee a comfortable fit and suitable match for your body.

To establish your correct bra size, you'll need two key measurements: your band size and your cup size. Start by wearing a non-padded bra, standing straight with your arms relaxed. Use a soft measuring tape to measure snugly around your natural waistline, just beneath your bust. This measurement is your band size. Ensure the tape is level and parallel to the floor. Record this measurement in inches or centimeters, based on the size chart you'll use.

Next, measure around the fullest part of your bust, keeping the tape comfortably snug but not tight. This gives you your bust size. To calculate your cup size, subtract your band size from your bust measurement. The difference indicates your cup size: for instance, a 1-inch difference equates to an A cup, 2 inches to a B cup, and so forth. Since most European countries use centimeters and U.S. sizes are typically in inches, always refer to the size or conversion chart specific to the brand or country you're shopping from.

Because sizing can differ between manufacturers and regions, it's wise to consult a bra size chart before purchasing. For example, a UK size 32DD translates to a European size 70E. These charts help match your measurements to the correct size, whether you're looking at European, UK, or Australian sizes.
