Breast size and bra size chart with sample images

There is some confusion around about how to name the sizes of a woman’s breasts and bras, since different measurements and sizes are used in different countries and geographic areas.

In a company like Model-Studios, which deals with clients and lingerie models from all over the world, we have thought it would be appropriate to create the following list to serve as a standard guide for all parties and thus avoid confusion that can lead to delays in works.

The size of a bra always depends on two factors: the circumference of the body just below the breasts (called band size) and the circumference above the breasts, usually at the level of the nipples (called bust size).

The first is normally expressed with a number, usually corresponding to centimetres or inches, while the second is expressed with a letter that depends on the difference between both measurements. This letter is known as the cup size.

Cup conversion chart.
