How to measure your bra size
FOLLOW THESE STEPS
STEP 1: TAKING THE MEASUREMENTS
Two measurements need to be taken. The ribcage circumference (measurement A) and the bust circumference (measurement B). Both measurements need to be recorded in inches. The measuring tape should sit firmly, but not tightly against the skin. You should be breathing out when taking the measurements.
STEP 2: DETERMINING THE BAND SIZE
Measurement A will determine the band size.
28” = size 6 38" = size 16
30” = size 8 40" = size 18
32” = size 10 42" = size 20
34” = size 12 44" = size 22
36” = size 14 46" = size 24
STEP 3: DETERMINING THE CUP SIZE
Determine the cup size by doing a simple calculation to measure the difference between the ribcage size and the bust size.
Measurement B (in inches) – Measurement A (in inches) = a difference of ??
Eg Measurement B = 40", Measurement A = 36” = difference of 4” = D cup
Eg Measurement B = 50”, Measurement A = 42” = difference of 8” = FF or G cup
Difference of 1 = A cup Difference of 7 = F cup
Difference of 2 = B cup Difference of 8 = FF/G cup
Difference of 3 = C cup Difference of 9 = G/GG cup
Difference of 4 = D cup Difference of 10 = GG/H cup
Difference of 5 = DD cup Difference of 11 = H/HH cup
Difference of 6 = E cup Difference of 12 = J cup
STEP 4: PUTTING IT ALL TOGETHER
If Measurement A is 32”, then the ribcage size should be a 10. If Measurement B is 36”, then the difference between Measurement A and B is 4 inches, which will mean a cup size D. This example is a 10D.
Another example. If Measurement A is 38”, then the ribcage size should be a 16. If Measurement B is 45”, then the difference between Measurement A and B is 7 inches, which will mean a cup size F. This example is a 16F.
STEP 5: TROUBLE SHOOTING
This isn’t uncommon, there could be a few different reasons for this.
The tape measurement system isn’t a perfect system (there isn’t one!), but it generally works as a very good guide.It can be difficult to measure yourself. Especially without experience. So it’s not uncommon to make the odd mistake when learning these things. Make sure you are using the inches, not cm’s.8/10 women wear the wrong size bra. It is very common that women are wearing bras sizes that are extremely different to what they may be fitted in to in a fitting.
If your size is not aligning with your expectations then send us an email with some detail like what measurements you are getting for both measurements A + B, what size you have been wearing, what t-shirt size you would usually wear (eg 8, 12, 20) and some insight into whether you feel you have been wearing the right size bra. We will be able to guide you better with this info.
