With that said, here are some frequently asked questions about 30B bras as well as the answers:
Is 30B smaller than 32A?
A 30B bra is 1 band smaller than the 32A. Generally, the difference between the underbust and the overbust denote the cup size alphabet. When the difference is one inch, the cup size is A. When the difference is two inches, the cup size is B.
However, a 30B and 32A are sister sizes, i.e., they have the same cup size but different band sizes. With these two bras, a 32A has a bigger band size than a 30B.
Is 30B bra size small or medium?
30B falls under the small breasts category. A woman with 30 inches band size is a woman with slender figure and B cup is also not a big cup size.
What is 30 bra size in CM?
In terms of centimeters, a woman who wears a 30B bra size measure 61-71 cm on the underbust and 79-81 cm on the overbust. However, a 30 bra size does not give us the full picture when we don’t know the cup size. For example, a 30B and 30D are not the same size. Generally, bras that are higher up in the alphabet are larger than those that are lower in the alphabet.
Therefore, a 30A bra size is smaller than a 30G bra size. This means that to get the correct 30 bra size in cm, you have to specify the cup size also.
