A cup size is measured according to the band size. Each letter represents an inch more than the band. For instance, if a bra is a 32B, it means the measurement around the rib cage is 32" and the measurement including rib cage and the swell of the breasts is 34". So, if the cup is a D, it means the swell of the breasts are 4" more than the rib cage. If the bra is a 36D, the rib cage would be 36", and the rib cage and breasts would be 40". For a smaller framed woman, the average in the United States is a 34B. For a woman with a larger frame, the average is a 34DD. Keep in mind, these are just the averages. There is quite a variety of larger and smaller sizes.
