Bra sizes in UK

0 618

‘E is the new C’, some bra fitters say. How so? With the range of bra sizes growing to cater for the needs of women of all kinds of build, bra sizes such as E and bands as narrow as 28 inches are becoming a standard in lingerie shops.

You may be well aware that many stereotypes arose around cup sizes. According to popular beliefs B is average and DD is a ‘celebrity’ bra size. Yet, cup sizes mean virtually nothing on their own without the one crucial aspect: the band size. For example, a woman who wears a 34C cup has more breast tissue than a woman who fits into 30C.

What a cup size really is, is the difference between your rib cage and bust circumferences. In practice, this means that if you choose a narrower band than usually, you should go up in a cup size.

A well-fitted bra is an indispensable clothing item for every woman. Whether you are looking for an everyday T-shirt bra, sensual lingerie or a swimming suit top, it is crucial to know your measurements. Size tables tend to be confusing, as they differ depending on a country of production and a particular brand. It is always a good idea to make sure whether your usual size matches the table of the given manufacturer.

Below you will find a rough guide to UK bra sizes.

First you need to find your band size:


Rib cage measurements (cm) 58-62 63-67 68-72 73-77 78-82 83-87 88-92 93-97 98-102 103-107
UK band size (inches) 28 30 32 34 36 38 40 42 44 46


And then calculate the difference between your rib cage and bust circumference to determine your cup size:

Technically Scotland doesn't count because they abolished the use of counties, hence why Inverness shire is not on the list.
