How to Measure Your Bras Size
Measure your underbust (the ribcage directly below the bust) snugly with a tape measure — this gives the band size. Then measure the fullest part of the bust loosely. The difference between bust and underbust measurements determines your cup size. Each inch (or 2.5 cm) of difference equals one cup letter. Wear a non-padded bra or go braless for the most accurate result.
Understanding EU and AU Sizing
European (EU) sizes follow the Continental European sizing system, which uses a single number scale across most of Europe. This system is based on the Paris Point for footwear (each size equals 6.67 mm of foot length) and on centimetre-based body measurements for clothing. EU sizing is generally considered more standardised than US sizing, though Italian and Scandinavian brands sometimes run smaller or larger.
Australian (AU) bra sizing follows the same band-number system as UK sizing but uses a different numbering offset — an AU 12, for example, is equivalent to a US 34 or UK 34. Australian sizing is common in Australia and New Zealand. Cup letters (A, B, C, etc.) work the same way as in the UK system.
Tips for Converting Women's Bras Sizes
Bra sizes consist of a band number (underbust measurement) and a cup letter (the difference between bust and underbust). Both must be correct for a good fit.
Sister sizes share the same cup volume at different band lengths — for example, 34C, 36B, and 32D all hold the same breast volume. If your band size is between two numbers, try a sister size in the adjacent band.
Up to 80% of women wear the wrong bra size according to lingerie fitting specialists. Getting professionally fitted or carefully self-measuring can dramatically improve comfort.
