Bra Cup Sizes (Smallest to Biggest)

Bra Cup Sizes (Smallest to Biggest)

Which is the smallest bra cup? What about the largest cup?

Well, the answers to these questions really depend on the manufacturer of the bra. Not all manufacturers make bras of all sizes. In fact, if you are full figured, you will find that only a few manufacturers cater for your size.

Generally, the smallest bra cup size available in most stores would be an AA. An AA cup measurement means that when the breast tissue is measured at the fullest area, it is less than one inch larger than the measurement of the underbust.

If you are looking for a bra for a small chest, you are not likely to require one with an underwire as your breasts are not likely to be too heavy to require support.  This means you won’t have a problem finding both bras and bralettes for your size!

There is no limit to how large a bra can get. However, the design usually has to be modified for full figured women. The customization can end up being quite expensive.

In most stores, you will find bras going up to an F cup. A couple of stores will even go up to a K cup.

The bra cup size depends on the measurement of the underbust (under-band) and overbust (the measurement of your bust passing through the nipples). The cup is determined by the difference between the two measurements.

However, keep in mind that not all brands are standardized. Therefore, you should always check the size guide provided by a company.

Bra Cup Sizes

The bra cup size is determined by the manufacturer. Some manufacturers offer a variety of bras from size 32, while other start their sizing from 28.

Generally, Asian bra manufacturers start their sizing from 32 while brands from Europe start from 28.

With that said, let’s look at all the bra cup sizes, from smallest to largest.
