How Much Bigger Is A Bra Cup Size?

Last Updated on March 21, 2022 by Sarah Keene

The larger the band size, the larger the cup. Therefore, the cup of 34B is the same as 32C or 36A.

Considering this, which cup size is bigger A or C? If your bust size is less than 1 inch bigger than your band size, you’re a cup size AA. 1-inch difference = A. 2-inch difference = B. 3-inch difference = C.

Subsequently, how do I know if I need a bigger bra cup size? If there are gaps between the cup and your breast, you’re wearing a cup size too big. If you find your breast spilling over the top, side, or bottom of the cup, you most likely need to go up in size. You also need to consider a larger cup size if the underwire or bottom of the bra is resting on your breasts.

Beside the above, is an A cup small? Generally, the A cup is considered the smallest available but for some this is still too big and compensating with a smaller band size won’t help. If you want something that’s going to fit your form you’ll have to go down a level to an AA or even AAA cup.
