What is bra size?

Bra size is a measurement system used to indicate the size of a person's breasts and the appropriate size of bra needed to provide support and coverage. It typically consists of two components: the band size and the cup size.

Band Size:

The band size refers to the measurement around the ribcage just below the breasts. It represents the circumference of the torso beneath the bust and is expressed in inches or centimeters. For example, a common band size might be 36 inches or 80 centimeters.

Cup Size:

The cup size indicates the volume or space needed to accommodate the breast tissue. It is determined by the difference between the ribcage measurement and the bust measurement, which is taken around the fullest part of the breasts. Different letters, such as A, B, C, D, and so on, are assigned to correspond to specific cup sizes. In general, as the difference between the ribcage measurement and the bust measurement increases, the cup size increases.

Therefore, bra size is expressed as a combination of the band size and the cup size. For instance, a bra size of 36B or 80B signifies a band size of 36 inches or 80 centimeters and a cup size of B.

Bra sizes can vary among different brands and countries, as various sizing systems may be used. It is always recommended to get professionally measured or to refer to size charts provided by specific brands to ensure an accurate and comfortable fit.
