All About B Cup Bra Size

What is B cup bra size?

A "B cup" bra size generally indicates a moderate cup size, where the difference between the bust and band measurements is approximately 2 inches. This size is considered medium, larger than an A cup but smaller than a C cup for the same band size.

How Is It Measured?

To measure

To measure your bra size, you'll need two measurements: the underbust and the overbust (the fullest part of your breasts). Wrap a measuring tape around your bust and note the numbers. You can then use a bra size calculator or bra size chart to determine the correct size. Common bra sizes consist of a number and a letter: the number denotes the band size, and the letter denotes the cup size.

Difference from Other Sizes

In bra sizing, the letters A, B, C, D, etc., represent the difference in inches between the bust and underband measurements, with each letter corresponding to a one-inch increment. Specifically, an A cup indicates a one-inch difference, while a B cup signifies a two-inch difference.

Cup Size	Inch Difference
A Cup	1 Inch
B Cup	2 Inch
C Cup	3 Inch
D Cup	4 Inch
DD or E Cup	5 - 6 Inches
DDD or F Cup	6 - 7 Inches
G Cup	7 - 8 Inches

For Example:
When your Bust = 34 inches and if your Band is =32 inches, 34-32 = 2 inches. Then 32 B is your bra size.
