International Bra Cup Size Systems

Finding the correct bra cup size is easy using our copyright to-scale bra cup conversion chart. If you’ve already had a professional bra fitting you can work from the comparison table to find your cup size in the bra style of your choice. We recommend choosing a large cup size specialist for your fitting regardless of your cup size, they’re more likely to recommend the correct size for you than a generic bra store which may only stock cups to E or F.


EU

The European Standard (Metric Bra Cup Size) System runs in consecutive alphabetical order. The difference between each cup size is 2cm, ie:


B Cup, C Cup, D Cup, E Cup, F Cup, G Cup, H Cup, I Cup, J Cup, K Cup, L Cup


It can be easier to find a perfect fit with this system: the slightly smaller difference between cups seems to lessen the incidence of women being between sizes.


UK/CAN

The cup size system used in the UK and Canada is also the most common sizing method for large cup bra ranges regardless of their country of origin. Imperial Cup Sizing of one inch between cup sizes applies for cups D and beyond. B & C cups are based on dressmaking pattern standards relevant to dress size. UK sizing uses a large number of double letters but omits I cup because of the confusion with both L & J cups in some typesets.


B Cup, C Cup, D Cup, DD Cup, E Cup, F Cup, FF Cup, G Cup, GG Cup, H Cup, HH Cup, J Cup, JJ Cup, K Cup, KK Cup, L Cup


AU/NZ

Australia and New Zealand also imply an imperial sizing method in which the difference between cup sizes for cups D and beyond is one inch. Again the B & C cups are based on dressmaking pattern standards with the actual distance between cups varying according to the dress size itself. Australian sizing includes a DD cup, followed by an E cup and then runs in consecutive alphabetical order, however as for the UK method, it also omits the I cup from this sequence, ie:



B Cup, C Cup, D Cup, DD Cup, E Cup, F Cup, H Cup, I Cup, J Cup, K Cup, L Cup



USA/ASIA

The USA system is another imperial sizing method in which the difference between cup sizes for cups D and beyond is one inch. Again the B & C cups are based on dressmaking pattern standards with a smaller difference between cups and relative to dress size. The US system of cup sizing adopted by many Asian nations uses a DD and DDD cup (more recently these are commonly being relabelled E & F cup) followed directly by the G Cup. Unlike the UK/CAN & AU/NZ models, the US system includes an I cup, ie:

B Cup, C Cup, D Cup, DD (E) Cup, DDD (F) Cup, G Cup, H Cup, I Cup, J Cup, K Cup, L Cup
