Bra sizes aren’t universal, and they vary significantly from country to country. That’s because measurement methods and standards often differ.
So, why does bra size conversion matter? Well, if you’re shopping online from international retailers, traveling abroad, or just interested in trying out a brand from another country, you’ll need to know how to convert your size.
This guide offers a comprehensive overview of bra chart conversion, covering major international sizing systems, plus some tips for finding the perfect fit, wherever you are.
Understanding International Bra Sizing Systems
Bra sizes aren’t universal. What’s a 34C in the United States might not be the same in Europe. Here’s a quick rundown of how bra sizing varies across the globe:
- United States (US): Uses a standard inch-based system.
- United Kingdom (UK): Similar to the US, but cup sizes can differ after DD.
- Europe (EU): Uses the metric system (centimeters) for band size.
- Australia/New Zealand (AU/NZ): Similar to UK sizing.
- France/Spain (FR/SP): Uses a different band size calculation than the rest of Europe.
The Band and Cup: The Basics
Understanding band and cup measurements is key to finding the right fit, no matter where you are.
- Band size: The measurement around your body directly under your breasts.
- Cup size: The difference between your bust measurement (around the fullest part of your breasts) and your band measurement.
Cup sizes tend to vary more across countries than band sizes do.
Bra Size Conversion Charts: A Detailed Comparison
Navigating bra sizes across different countries can feel like learning a new language! Here’s a breakdown to help you understand the common conversions:
US to UK Conversion
Good news: US and UK band sizes are usually the same. However, cup sizes can differ, particularly for larger busts. For example, a US 34D is typically a UK 34D, but a US 34G might translate to a UK 34F.
US to EU Conversion
To convert from a US to an EU band size, add 30 to the US size if it’s an even number, or 32 if it’s an odd number. So, a US 34 would be approximately an EU 75.
EU cup sizes generally line up with UK sizes, but it’s always wise to double-check a conversion chart, particularly if you wear an uncommon size.
US to Australian/New Zealand Conversion
Generally, Australian and New Zealand bra sizes mirror UK sizes, so use the same conversion as above.
US to France/Spain Conversion
French and Spanish band sizes are calculated by adding 15 to the EU band size. For example, an EU 75 becomes a FR/SP 90. Converting cup sizes accurately requires a detailed conversion chart.
How to measure your bra size
Finding the right bra starts with measuring your bra size accurately. Here’s how to do it:
- Measure your band size: Use a measuring tape to measure around your torso right under your breasts. Round to the closest whole number. If the number is even, don’t add anything. If it’s odd, add one inch. This is your band size.
- Measure your bust size: Measure around the fullest part of your chest. Make sure the tape isn’t too tight.
- Calculate your cup size: Subtract your band size from your bust size. The difference determines your cup size. A = 1 inch, B = 2 inches, C = 3 inches, and so on.
You should remeasure your bra size every year. You should also measure after any major weight gain or loss.
What can affect your bra size and fit?
Bra sizes aren’t uniform, so you can’t assume that a 34C from one brand will fit the same as a 34C from another. If you can, always check the brand’s sizing chart.
The style of bra you choose can also impact fit. A balconette will fit differently than a full-coverage or a sports bra.
Finally, changes in your body can affect your bra size. Weight fluctuations, pregnancy, and hormonal shifts can all change your cup and band size.
Frequently Asked Questions
Is a 36C bigger than a 34C?
Yes, a 36C is bigger than a 34C, but only in the band size. Both have the same cup volume (the “C”). The number refers to the band size, which is the circumference around your ribcage just under your breasts. So, a 36C has a bigger band and will fit a larger ribcage. If you need a bigger cup, you’d go up in the letter (D, DD, etc.), not the number.
Will losing 20 pounds change my bra size?
It’s definitely possible! Weight loss often affects breast tissue and your ribcage circumference. You might find your band size decreases (36 to a 34, for example), and/or your cup size changes. After losing weight, it’s a good idea to remeasure yourself or get professionally fitted to ensure you’re wearing the right bra size for optimal comfort and support. Remember, your bra size is not a fixed number and can fluctuate with weight changes, hormonal shifts, and even different bra styles. It’s all about finding the best fit for your current body!
Key Takeaways
Navigating international bra sizing can feel confusing. But if you understand the different sizing systems, use a conversion chart, and measure yourself accurately, you’re one step closer to finding the right fit.
Whenever possible, try on bras in person to make sure they’re comfortable and supportive. And don’t be afraid to experiment with different sizes and brands to find what works best for your body.
