Finding a bra that actually fits is essential. An uncomfortable bra can lead to back pain, bad posture, and general misery. And if you’re working out, proper fit and support are even more critical.
The trouble is, bra sizes aren’t consistent. They vary from country to country and even between different brands. Studies show that many women are wearing the wrong size bra, and that’s why a conversion chart for bra sizes may be helpful.
This article will provide a comprehensive guide to bra size conversion, including international conversions and tips for finding your perfect fit.
Measuring Your Bra Size
Finding the right bra starts with knowing your measurements. Here’s how to get them:
Measuring Your Underbust
Using a soft measuring tape (or a piece of string you can measure later with a ruler), measure snugly around your ribcage just under your breasts. Round up to the nearest whole number. This measurement determines your bra’s band size.
Measuring Your Cup Size
Again, using your measuring tape or string, measure around the fullest part of your bust. Round up to the nearest whole number.
To figure out your cup size, subtract your underbust measurement from your bust measurement. Each inch of difference corresponds to a cup size: 1 inch = A, 2 inches = B, 3 inches = C, and so on.
Bra size charts: US, UK, and EU
Bra sizes can vary depending on whether you’re in the United States, the United Kingdom, or Europe. Here are a few general guidelines that may help you find the right fit.
US to UK conversion
In many cases, bra sizes in the US and the UK are the same. For example, a 34C in the US is often a 34C in the UK. However, it’s important to double-check the fit, particularly if you wear a larger cup size.
UK to EU conversion
Bra sizes in the UK and Europe are often different. For example, a UK 32B is equivalent to an EU 70B, and a UK 34C is an EU 75C. Sizing in Europe is based on centimeters.
Why brand-specific charts matter
Keep in mind that bra sizes can vary quite a bit from brand to brand. To be sure you’re getting the right fit, it’s a good idea to look at the brand’s size chart before you order.
International Bra Size Conversion Details
Bra sizing gets even more complicated when you’re talking about international sizes. Here’s a little about Japanese bra sizes, along with a few notes on how to navigate the world of international bra sizing.
Japanese Bra Sizes
To convert from Japanese to U.S. bra sizes, you’ll need to know your band size in centimeters and your bust size in inches. Here are a few examples:
- Band Size 65cm (30″), Bust Size 29.5″ = A65
- Band Size 70cm (32″), Bust Size 31.5″ = A70
- Band Size 75cm (34″), Bust Size 33.5″ = A75
- Band Size 80cm (36″), Bust Size 35.4″ = A80
- Band Size 85cm (38″), Bust Size 37.4″ = A85
Other International Considerations
Many countries have their own sizing systems, so if you’re planning to shop for bras while traveling or ordering online, you’ll want to do a little research to make sure you’re ordering the right size.
Frequently Asked Questions
How can I calculate my bra size?
Calculating your bra size involves two measurements: your band size and your bust size. Measure snugly around your ribcage directly under your breasts for your band size. Then, measure loosely around the fullest part of your bust. Subtract your band size from your bust size. Each inch difference corresponds to a cup size (1 inch = A, 2 inches = B, 3 inches = C, etc.).
What is 34G bra size equivalent to US?
Bra sizing can get confusing because of the differences between countries. A 34G in UK sizing is typically equivalent to a 34I in US sizing. Sizing variations can occur depending on the brand, so it’s always best to consult the specific brand’s size chart.
Why add 4 inches to band size?
This is an outdated practice from when bra bands were less elastic. This method is no longer recommended, as it often leads to inaccurate measurements and ill-fitting bras. Using your direct underbust measurement is the most reliable way to determine your band size.
How to convert measurements to bra size?
After obtaining your band and bust measurements, subtract the band size from the bust size. The resulting number corresponds to your cup size. For example, if your band size is 32 inches and your bust size is 36 inches, the difference is 4 inches, indicating a D cup. So your bra size would be 32D.
Summary
To make sure your bra is a good fit, check the straps to see that they stay put and don’t dig into your shoulders. The band should fit snugly and provide the right amount of support. And to really test the support, try doing a few jumping jacks to see if you have enough bounce control.
It’s important to get fitted regularly to get the best size for comfort and support. When your bra fits well, you’ll feel great!
