What is the letter ABCD in bra?

ABCD represents the volume of the breasts i.e. how much flesh is in the boobs. A or AA represents a small volume B represents a bigger volume than A, C represents a bigger volume than B, and so on. Let’s look in detail at how to determine the volume of breasts in the letters.

How breast volume is mapped to alphabets:

Each letter size is the one-inch height of the breasts from the skin to the areola. A is one inch from the chest, B is two inches from the chest and C is three inches from the chest skin—a double size DD represents a wider breast, not a heavier breast DD is not an E cup size.

Measuring breast volume is simple than you think. Breasts volume is also called cup size or bust size. It is measured by wrapping a measuring tape around your breasts as shown in the figure. You can know more detail about how to correctly measure breast volume at home.

Bras have two parts of their size. The band size the measurement around the rib cage, measured in inches or centimeters. In inches, band size goes from 28-50 or 70-125 for centimeters. The cup size is measured around the fullest part of the breasts, i.e: the nipple.

If the band size is 34 and the cup size is 35 then the bra size will be 34A see the following formula:

Bra size is
Band size. (difference of band and cup size).

The 1-inch difference is A two-inch difference is B and so on. A shows breast volume that is 1 inch 2.5cm larger than band size. B that is two inches bigger than band C that is three and so on.

Upon reaching D cup size get complicated as the breast becomes heavier and wider. So to cover wider areas DD/DDD sizes are also available that are the same in height as D but wider than D.
