Determine your bra size

Category: Fitting, Measuring |

To offer your breasts the right kind of support and to prevent back pain, it is important that you know your bra size. You can ask someone in a lingerie shop to measure your bra size, but you can also do it yourself.

Measuring your bra size

A bra size is made up of two components: the size and the cup. To determine your bra size, you start with determining your size, by measuring the band size:
Take of your bra and use measuring tape to measure the width of your body just below your breasts. Tighten the tape, but make sure it does not squeezing your body. Take these measurements and round them up to the nearest whole inch. That means that 27 2/8” becomes 27”, while 27 5/8” becomes 28”. If the result is an even number, add 4 inches, and you have your band size. If the result is an odd number, add 5 inches,

For measuring your cup size, first measure your breasts at the level of your nipples. Loosen the measuring tape a bit to get the best results. Round this number up or down to the nearest whole inch and detract the band size from this number. Use the table below to find your size:

Difference Standard cup size (UK)
0″-1/2″ (1.3 cm) Cup AA (AA)
1/2″- 1″ (2.6 cm) Cup A (A)
2″ (5.1 cm) Cup B (B)
3″ (7.6 cm) Cup C (C)
4″ (10.2 cm) Cup D (D)
5″ (12.7 cm) Cup DD or Cup E (DD)
6″ (15.2 cm) Cup DDD or Cup F (E)
7″ (17.8 cm) Cup G (F)
8″ (20.3 cm) Cup H (FF)
9″ (22.9 cm) Cup I (G)
10″ (25.4 cm) Cup J (GG)
11” (27.9 cm) Cup K (H)

Please note:
It is important to measure your bra size regularly, since on average, the bra size of a woman changes six times. This is because of age, pregnancies, gaining or losing weight, and hormonal changes.
Sizes can also differ per manufacturer and model, so always try on a bra before you buy it. Your figure and the size of your breasts also influence your bra size. It is possible that the size in the sizing table is another one than that of the bra you buy. The table is based on US sizes and UK sizes (between brackets). Sizes for other countries may differ.
