Bra sizes are definitely not created equal. Numbers and letters can vary wildly between countries and even between brands in the same country. It’s enough to make you want to give up and just wear comfy bralettes forever.
But a well-fitting bra is so important for comfort, support, and even your overall well-being. So, to help you navigate the confusing world of international bra size charts, we’ve put together this guide to help you find the perfect fit, no matter where you are or what brand you’re buying.
Breaking down bra size
To get a better handle on international bra sizing, it helps to understand how sizes are determined.
Band size
The number in a bra size refers to the band size. It’s a measurement of the circumference of your chest directly under your breasts.
Cup size
The letter or letters in a bra size refer to the cup size, which is calculated by subtracting the band size from the bust measurement at the fullest part of your chest. This difference determines the cup size.
Sizing systems
Different countries use different sizing systems. The key systems are those used in the United States, the United Kingdom, the European Union, France, and Australia. Because the sizing methods are different, you’ll need to use a conversion chart to make sure you’re getting the right fit.
International bra size conversion charts
Bra sizing can be so tricky! Here are some general guidelines to help you translate your US bra size to other sizing systems.
- US to UK: In most cases, the band and cup size will be the same in both countries. A US 32C is usually a UK 32C.
- US to EU: The European Union uses a different sizing system. A US 34B is roughly equivalent to a 75B in the EU.
- US to French: French sizes are often based on the EU band size, plus 15. So if you’re a 75B in the EU, you’re likely a 90B in France.
- US to Australian: Australian sizing tends to be similar to UK sizing.
Using conversion charts can be a lifesaver when you’re shopping for bras from international brands. Just keep in mind that bra sizes can vary a bit from brand to brand.
Measuring Yourself for Accurate Bra Sizing
Getting an accurate bra size starts with taking careful measurements.
Underbust Measurement
Measure snugly around your ribcage, keeping the measuring tape directly under your bust. Use that measurement to determine your band size.
Bust Measurement
Measure around the fullest part of your bust. Then, subtract your underbust measurement from this bust measurement to get your cup size.
Tips for Accurate Measurement
Measuring yourself can be tricky, so consider asking a friend or family member to help. Also, make sure you’re wearing a non-padded bra when you take your measurements, so you get the truest results.
Troubleshooting Bra Fit Issues
Is your bra not quite right? Here’s how to troubleshoot some common fit problems:
- Band Rides Up: The band should sit snugly and horizontally around your torso. If it’s riding up, try a smaller band size.
- Band Too Tight: Feeling constricted? Go up a band size.
- Cups Gapping: Empty space in the cups? Try a smaller cup size.
- Spillage: Overflowing cups? You need a larger cup size.
- Straps Digging: Adjust the straps. They should support, not dig.
- Straps Slipping: Tighten the straps or look for a bra with different strap placement.
- Underwire Digging: If the underwire digs, it could be too small. If it feels like you are being squashed, consider a larger bra size. If the digging is under your arms, it may be that you need a larger cup size.
Frequently Asked Questions
Are bra sizes the same internationally?
Nope! Bra sizing isn’t universal, and can vary significantly between countries. What’s a 34C in the US might be a completely different size in the UK, EU, or Australia. This is due to different measurement systems and sizing standards. Always check a conversion chart specific to the brand or region when buying bras internationally to ensure the best fit.
What is EU in bra size?
“EU” in bra size refers to the European sizing system, which uses centimeters for band measurements. An EU size will typically be a higher number than its US equivalent. For example, a US 34 band size is approximately an EU 75. Cup sizes are also different; while some EU countries use the same letters as the US, others use different systems, so always double-check a conversion chart.
What is 40-90 bra size in the US?
The “40” refers to the band size in centimeters in the EU system, and “90” refers to the bust circumference. To convert to US sizes, you would generally subtract about 12 cm from the band size, so 90 cm is about 35 inches. A bra size of 40-90 in EU measurements is roughly equivalent to a 36B in US sizing.
Wrapping Up
So, figuring out international bra sizes means understanding the different sizing systems, using conversion charts, and taking your measurements carefully.
Keep in mind that finding the perfect fit might take some experimenting. Sizes can be different from one manufacturer to the next.
When choosing a bra, focus on comfort and support. And if you’re not sure what size you need, don’t be afraid to ask a professional for help. A good bra fitting can make all the difference!
