20A Bra Size – Find Your Perfect Fit
Understanding the 20A Bra Size
The 20A bra size is a specific fit designed for those with a broader band size and a smaller bust volume. In Australian sizing, the number refers to your band size—the measurement around your ribcage. A 20 band typically suits an underbust measurement of around 85 cm. The letter “A” refers to the cup size—indicating a smaller bust. Together, this size caters to bodies needing wider bands with a petite bust. Finding the perfect bra in this size offers better comfort, less slipping, and a fit tailored to your body.

How to Measure: Quick Tape Measure Guide
Use a soft tape measure and follow these two simple steps:
- Band size: Measure firmly under your bust and round to the nearest even number in centimetres.
- Bust measurement: Measure around the fullest part of your bust while standing straight.
Subtract your band size from your bust measurement. A 1–2 cm difference typically indicates an A Cup. Still unsure? Use our size chart or book a virtual fitting with our expert team.
