Australian Bra Size Chart

This Australian bra size chart covers AU and NZ labels beside US, UK, EU, and French equivalents. It is helpful when a brand lists sizes such as 10C, 12D, or 14DD and you want the matching international row.

Australian bands use clothing-style numbers, so they look much smaller than US or UK bands. The table keeps the conversion on one row so the label difference does not hide the actual fit target.

How to use this chart

Measure under the bust and around the fullest part of the bust, then find the matching row. Read the Australian column for the AU or NZ label and compare the other systems if you shop internationally.

If you already know your US size, subtracting 22 from the US band is a common shorthand for the Australian band, but the full row is more reliable because the cup label matters too.

Find my size

Australian bands are US bands minus 22

A US 34 band appears as AU 12 in this chart, which follows the common US-minus-22 relationship. That difference is a label convention, not a sign that the bra is smaller.

Australian cup labels often follow a UK-like sequence in fuller cups. If you are above D, compare the row carefully instead of assuming US and AU letters match exactly.

Brand sizing still matters

A chart gives you a standard reference, but bras are products with shape, stretch, wire width, cup depth, and construction choices. Two bras with the same printed label can feel different if one brand uses firm elastic and another uses a stretchier band.

Use this page to identify the closest label, then check the retailer's chart and the real fit. If the cup volume feels close but the band feels wrong, compare sister sizes before jumping to an unrelated cup letter.

Unusual sizes and sport bras

What if my size is outside this chart?

The active Wearavo dataset covers common reference sizes. If your measurements fall outside this range, use the same measurement principles and compare specialist brand charts that carry extended bands or cups.

Should sport bras use the same chart?

Sport bras often use firmer fabrics, compression, or alpha sizing. Start with your chart size, then check the sport bra's own support level, cup structure, and band guidance.

FAQ

What is US 34C in Australian sizing?

In this chart, US 34C maps to AU 12C. The band label changes, but the row represents the same general fit target.

Are Australian and New Zealand bra sizes the same?

They are commonly treated together as AU/NZ sizing. Individual retailers can still have their own fit notes.

Do AU cup letters follow US or UK sizing?

For the active Wearavo table, Australian cups follow the UK-style mapping used in the shared data. Check fuller cup labels carefully when shopping across brands.

Why is my AU band number so different?

Australian bands use a different numbering convention. A US 34 can map to AU 12, so compare equivalent rows rather than the number alone.
