Navigating through the world of lingerie can sometimes be a challenging task, especially when it comes to understanding bra sizes in different countries. With brands and designers from across the globe using varying standards, it's essential to know how to convert your bra size accurately. Our comprehensive bra size conversion chart is here to assist you in this task.
This handy guide allows you to convert between the bra sizing systems used in the United States, United Kingdom, Europe, France, Spain, Japan, and Australia. Understanding these conversions is crucial for online shopping, international purchases, or simply when you encounter a foreign brand. For faster bra size conversions or calculations you can also use our Bra Size Calculator.
How to Use the Chart
- Find Your US Size: Begin by locating your US bra size on the chart. This is typically composed of a number (representing your band size) and a letter (indicating your cup size).
- Compare and Convert: Once you've found your US size, you can easily look across the chart to see your corresponding size in the UK, Europe, France, Spain, Japan, and Australia.
- Understand the Differences: It's important to note that while band sizes are generally consistent in measurement (inches or centimeters), cup sizes can vary significantly between countries. For instance, a US 'D' cup might not be the same as a UK 'D' cup.
Key Points to Remember
- Band Size Conversion: The band size, which is the number part of your bra size, is relatively straightforward to convert. However, remember that European sizes often use centimeters instead of inches.
- Cup Size Conversion: Cup sizes can be trickier. They don't always follow a direct alphabetical sequence after 'D' (e.g., DD, DDD/E, F in the US). Be aware of these variations when converting your size.
- Check for Sizing Guides: Always check the sizing guide provided by the brand or retailer, as some may have unique sizing charts.

Measurement Instructions
Tools needed
Measurement tape & a mirror.
Band Measurement Instructions
Stand in front of a mirror and wrap the measurement tape around your body, right underneath your breasts. Make sure the measurement tape is horizontal and wraps tightly around your body. The measurement you identify is your band size in inches. If you find yourself being between sizes, for instance 41, your correct size could be both 40 and 42.
Cup Size Measurement Instructions
Stand in front of a mirror and measure around the fullest part of your breast. In order to get the cup size, you would need to subtract the bust measurements from the band measurements.
Here's an example:
Cup Size = Bust Size - Band Size
0 = AA <1 = A 1 = B 2 = C 3 = D 4 = DD 5 = DDD/E 6 = F 7 = G 8 = H

FAQ on Bra Size Conversions
How do I find my bra size using the International Conversion Chart?
To find your bra size using the International Conversion Chart, start by knowing your current bra size in the US system, which includes your band size (a number) and your cup size (a letter). Then, locate your US bra size on the conversion chart to see how it translates into UK, European, France/Spain, Japan, and Australian sizes. Remember, band sizes are more uniform across countries, but cup sizes can vary significantly. For precise conversion, pay close attention to both the band and cup size columns in the chart.
Why do cup sizes vary so much between countries, and how can I ensure I'm choosing the right size?
Cup sizes vary between countries due to different sizing standards and methods of measurement. For example, after the size 'D', countries may not follow the same alphabetical sequence for cup sizes. To ensure you're choosing the right size, focus on the measurement instructions provided by the brand or retailer, considering the specific conversion for the country's sizing system you're looking into. Additionally, utilize tools like bra size calculators or consult with lingerie specialists for more personalized advice.
What's the best way to measure my band size at home?
The best way to measure your band size at home is by standing in front of a mirror with a measurement tape. Wrap the tape directly under your breasts, where the band of your bra would sit. Ensure the tape is horizontal around your body and snug but not too tight. Read the measurement in inches – this is your band size. If your measurement is an odd number or falls between sizes, consider trying both adjacent sizes for the best fit.
How do I calculate my cup size correctly?
To calculate your cup size, first measure around the fullest part of your breast to get your bust size. Then, subtract your band measurement (measured underneath the breasts) from your bust measurement. The difference in inches determines your cup size based on the standard conversion (e.g., a 1-inch difference is an 'A' cup, 2 inches is a 'B' cup, etc.). This method helps account for the volume of the breast tissue relative to the band size.
Can I use the same conversion chart for all brands and types of bras?
While the International Bra Size Conversion Chart provides a helpful starting point for converting sizes across different countries, it's essential to note that sizes may vary by brand and bra style. Always consult the specific brand's size guide or customer service for the most accurate sizing, especially for styles like sports bras, push-up bras, or bras made with unique materials.
What should I do if my converted bra size doesn't seem to fit well?
If your converted bra size doesn't seem to fit well, consider a few factors: the brand's specific sizing, the style of the bra, and your own body's changes over time. It might be helpful to get a professional fitting in-store, try different sizes around your converted size (one size up or down in band or cup), or reach out to the brand's customer service for advice. Remember, comfort and support are key, so don't hesitate to explore different options.
How often should I re-measure my bra size?
It's recommended to re-measure your bra size at least once a year or after any significant changes to your body, such as weight fluctuations, pregnancy, or changes in exercise habits. Regularly updating your measurements ensures you're always wearing the right size for optimal comfort and support.
By familiarizing yourself with the International Bra Size Conversion Chart and understanding how to measure your bra size accurately, you can navigate the world of lingerie with confidence, ensuring you always find the perfect fit, no matter where you shop.
