What is a 90D Bra Size in the US?
A 90D bra size in European sizing translates to a 40D in US sizing. This conversion is essential for accurate bra fitting, especially when shopping across different regions. Understanding these size conversions can significantly enhance comfort and support.
How to Convert Bra Sizes: 90D to US
Bra sizes can be confusing due to varying international standards. European sizes often use centimeters, while US sizes use inches. Here’s a simple breakdown:
- Band Size: European size 90 converts to a US size 40. This reflects the band measurement around the ribcage.
- Cup Size: The letter ‘D’ remains consistent between European and US sizing, indicating the same cup volume.
Why Accurate Bra Sizing Matters
Wearing the correct bra size is crucial for comfort and support. An ill-fitting bra can cause discomfort, poor posture, and even back pain. Ensuring the right fit can improve your overall well-being and confidence.
Understanding Bra Size Components
A bra size consists of two parts: the band size and the cup size. Here’s how they work:
- Band Size: This number represents the measurement around your ribcage. In the US, it is measured in inches, while in Europe, it is measured in centimeters.
- Cup Size: This letter denotes the volume of the breast. Although the letter remains the same across different regions, the actual volume can vary slightly due to measurement systems.
The Importance of Trying Different Sizes
Different brands may have slight variations in sizing. It’s advisable to try on several sizes and styles to find the best fit. Consider these tips:
- Try Multiple Brands: Each brand may fit differently, even within the same size.
- Check Fit in Different Positions: Ensure the bra fits well when standing, sitting, and moving.
- Look for Adjustable Features: Straps and band adjustments can help achieve a better fit.

Below is a comparison table showing how European sizes convert to US sizes:
| European Size | US Size | Cup Size Consistency |

How to Measure Bra Size at Home
To find your correct bra size, follow these steps:
- Measure Your Band Size: Wrap a measuring tape snugly around your ribcage, just under your bust. Round to the nearest whole number. Add 4 if even, and 5 if odd, to get your band size in inches.
- Measure Your Bust Size: Wrap the tape around the fullest part of your bust. Round to the nearest whole number.
- Calculate Cup Size: Subtract the band size from the bust size. Use the difference to determine your cup size (1 = A, 2 = B, 3 = C, 4 = D, etc.).
