You can easily measure your correct bra size on your own. Just follow the tables below. The sizing system for bras is different in different areas of the world. In the Nordic area we use EU standard. There are two measurements you must consider whilst measuring you bra size: band width (the circumference around your torso under your bust) as well as the measurement where the bust is at its fullest, often leveled at your nipples.
B – BAND WIDTH – CIRCUMFERENCE UNDER YOUR BUST
The measurement under your bust is called band width and is measured in cm which is rounded off to the nearest five-number. Measure around your back with a tape measure. The measuring tape should be tight while measuring. If your number is between two sizes, you should choose the smaller one since the bra will stretch out over time.
A – CUP SIZE
Cup sizes are specified with a letter. To come up with the right cup size you must measure where your bust is at its fullest. Measure while wearing a non-padded bra. The cup size is the difference between the measurement over your bust and the band width. For example if you measure 87 in band width, and 105 around your bust: 105 cm – 87 cm = 18 cm. Then your size is 85 C.
The cup width is proportional to your band width. A cup with the same volume can have different letters depending on which circuit you have under your bust. This will make the volume of the cup on size 85C equal to the cup size on 80D or 75E.
