How to Measure Your Bra Size: Band Size, Bust Size, Cup Size


Every woman knows how troublesome it can be to find a bra that fits. The reality however, is that most of us are not having our bra size correctly measured. Measuring the cup size and band size is not only important to ensure you feel comfortable, but also to protect your health! Poorly fitted bras can cause serious back pain, so make sure you take the time to measure yourself to ensure that your bra fits exactly as it is supposed to.

If you don’t like the idea of being measured for a bra at a store, then why not ask mum, sis or a good friend to do it for you (measuring yourself is not really ideal), then you can buy a bra with confidence, knowing you’re selecting the correct size for you.

The three measurements that should be taken to correctly fit your bra are as follows:

Band size of the bra

The band size refers to the measurement taken just below the bust.  This is measured by simply extending the dress making tape around the torso at the point where the band will sit. Measurements will need to be converted into Australian sizes – for example, if you measured 70 cm or 32 inches, you are likely to require a size 10 bra. Please see the chart below:

Australia 8 10 12 14 16 18 20 22 24
UK/US 30 32 34 36 38 40 42 44 46

Measurement above the bust

The second measurement that should be taken is done just above the bust. This measurement gives an indication of whether the woman has broad shoulders or narrow shoulders and upper torso. Taking this measurement can help to determine the size cup needed. If two women measure the same size at the mid bust point, but one has a much narrower torso, then this means that the actual cup size she will need is going to be larger than a woman with a broader torso.

Cup size

Measuring your bust size requires you to wrap a measuring tape around the centre of your bust, which is usually the nipples. Subtract your band size from your bust size to determine your cup size. Cup sizes are described using letters with the smallest size starting at A and working upward. Considered alongside the band measurement and the measurement above the bust, this helps to determine the right size cup to fit you correctly. If this is too big or too small, then the bra will either be loose, or you’ll end up with unflattering silhouette line where the breast is being squeezed over the top of the bra.
