How To Measure Your True Bra Size

Far too many women are wearing the wrong bra size. This can affect your breasts by leaving them unsupported, and can also cause you to have poor posture as well. It’s important to give your boobs the support they deserve, and its easy peasy to measure yourself to get an idea of your correct bra size.

Step 1 – Working Out Your Band Size
Get yourself a dressmakers tape measure (one of those soft ones).
Measure the dimensions of your ribcage directly beneath your bust whilst wearing a bra you think fits you really well. The tape should sit on the lower band of your bra.

Make sure that the tape is level at the front and back (use a mirror to help you) and that it is reasonably snug against your skin.

This measurement is what you use to work out your band size. Add five to this number to get the correct band. i.e. if you have a 27 inch measurement, you need a 32 band size for your bra. If you get an odd number i.e. 33 it is usually OK to go up to the next band size (i.e. 34). However, you might also want to try on the next band size down (i.e. 32) to check which is the best fit for you.

Step 2 – Working Out Your Cup Size

OK, now we have your bra band size we need to work out your cup size!

Measure around your bust at its fullest point. Again, make sure it sits evenly all the way around you and is snug against your body. The difference between this measurement and the band measurement we worked out previously is used to determine cup size.

For example. If you measured 27 inches under your bust, worked out from that you needed a 32 band size, and had a bust measurement of 36 inches, you would require a 32D bra.

This is worked out using the following: -

if the difference is:
less than 1 inch = AA cup
1 inch = A cup
2 inches = B cup
3 inches = C cup
4 inches = D cup
5 inches = DD cup
