🎯 Your Aussie Bra Size
Knowing your correct Australian bra size helps heaps when shopping for bras in Australia or from Aussie brands. No more guessing! This guide and our Australian bra size calculator make understanding Aussie bra sizes easy!
Australia uses centimeters (cm) for measurements. The band size is a number like your dress size (8, 10, 12, 14…) and the cup size is a letter (A, B, C, D, DD…). Let’s find out how to measure!
How to Measure for Your Australian Bra Size
Finding your Australian bra size is simple with a soft measuring tape and using centimeters (cm)! Getting measurements right is important for a good fit, as measurement guides like this one from the Craft Yarn Council show.
- Measure Your Underbust: Wear a comfy, non-padded bra or no bra. Breathe out normally. Wrap the tape measure firmly around your body, right underneath your breasts where the bra band sits. Keep the tape straight and snug.
Write down this number in cm. - Measure Your Bust (Overbust): Keep the tape level and wrap it loosely around the fullest part of your breasts. Don’t pull the tape too tight.
Write down this number in cm too. - Put Numbers in Calculator: Enter your underbust measurement and your bust (overbust) measurement in cm into the Australian bra size calculator above.
- Find Your Size: Click the calculate button! It will suggest your Australian bra size.
Easy Tip: Stand in front of a mirror to make sure the tape measure is straight all around. Asking a friend or family member for help can make it easier!
How an Australian Bra Size Work
Australian bra sizing is unique!
- Band Size: The number (8, 10, 12, 14…) is like Australian dress sizing and relates to your underbust measurement in cm. Each band size covers a range of cm.
- Size 8: ~63-67 cm underbust
- Size 10: ~68-72 cm underbust
- Size 12: ~73-77 cm underbust
- Size 14: ~78-82 cm underbust
(And so on, usually going up by 5cm per size)
- Cup Size: The letter (A, B, C, D, DD, E, F…) shows how much bigger your bust (overbust) measurement is compared to your underbust measurement. Unlike other systems that use the difference, Australian charts often list the actual overbust cm range for each cup within a specific band size.
- For example, for a size 12 band (73-77cm underbust):
- A cup might be ~87-89 cm overbust
- B cup might be ~89-91 cm overbust
- C cup might be ~91-93 cm overbust
- D cup might be ~93-95 cm overbust
- DD cup might be ~95-97 cm overbust
(These cm ranges change for each band size! This is why using a calculator or chart is important)
- For example, for a size 12 band (73-77cm underbust):
This system is also used in New Zealand.
What Your Australian Bra Size Means
Your calculated Australian bra size (like 12C or 14DD) helps you shop locally. Remember that sizes can feel a bit different between brands, even if they have the same size label!
You can compare your Aussie size to other systems using our US Bra Size Calculator or UK Bra size Calculator.
Our bodies change, so remeasuring every year is smart. If you feel between sizes, sister sizes might help. If a 12C band feels loose, try 10D (smaller band, bigger cup). If 12C feels tight, try 14B (bigger band, smaller cup). Our Sister Size Finder helps find these!
Fixing Common Australian Bra Size Fit Problems
Getting the right Aussie bra size can solve many common issues!
- Band Rides Up Back? The band number (10, 12, etc.) is probably too big. Try a smaller band number, but go up a cup letter (like change 14B to 12C).
- Straps Dig In? Check the band fit first! It should do most of the work. If straps still dig, the style might not suit you.
- Spilling Out of Cups? You need a bigger cup letter! Your breasts should fit smoothly inside.
- Gaps in Cups? The cup might be too big, or the bra shape is wrong for your breast shape. Try a smaller cup letter or a different style.
- Wire Pokes? The underwire should sit flat against your chest and curve around your breasts comfortably. If it pokes, the size or style is likely incorrect.
Changing US/UK/EU Sizes to Australian
Converting international sizes to Australian bra size requires using a conversion chart because the systems are quite different.
- UK to Australia: Band sizes are different (UK 32 ≈ AU 10, UK 34 ≈ AU 12). Cup sizes often align up to D/DD, but check carefully after that (UK E ≈ AU E, UK F ≈ AU F, UK FF ≈ AU G).
- US to Australia: Band sizes are different (US 32 ≈ AU 10, US 34 ≈ AU 12). Cup sizes often align up to D, but US uses DD, DDD, G while Australia uses DD, E, F, G. Conversion is needed.
- EU to Australia: Band sizes are different (EU 70 ≈ AU 10, EU 75 ≈ AU 12). Cup sizes often align up to D/DD, but check carefully after that.
Knowing how to measure accurately is key, as shown in guides like this one on taking body measurements. Always trust your cm measurements for Aussie sizing!
| Underbust (cm) | Australian Band Size | Approx. UK/US Band | Approx. EU Band |
|---|---|---|---|
| 63-67 cm | 8 | 30 | 65 |
| 68-72 cm | 10 | 32 | 70 |
| 73-77 cm | 12 | 34 | 75 |
| 78-82 cm | 14 | 36 | 80 |
| 83-87 cm | 16 | 38 | 85 |
