Believe it or not, 80% of women wear the wrong bra size almost all their life! Either the band size is wrong, or the cup size is completely incorrect. Either way, an incorrectly sized bra is not only uncomfortable but may also not do its job of supporting the breasts.

Do YOU know how to measure your bra size?
Do you know that bra size measurement should be taken every six months?
Do you know that bra size changes with weight fluctuations?

Yes, it is true. Bra size changes so often that you need to measure it every six months. If you don’t do that, you will continue to wear (or buy) a size that is no longer correct for you. This will not only make you uncomfortable, but will also lead to sagging breasts. So if you have not measured your bust size recently, do it now. Memsaab brings you the right technique to measure your bra size.

Measure Your Bra Size

You need a measuring tape to begin with. Follow the instructions given below to arrive at your bra size.

Your bra size actually contains two measurements. The first is your band measurement and the second is your cup measurement. For instance, size 36 C means that the band measurement is 36 and the cup measurement is C. For a perfectly fitting and comfortable bra, you must get both the measurements right.

Band Measurement

Band measurement is the diameter of your ribcage, just under your breast. It is quite easy to take. All you need to do is take a measure of your ribcage with the tape. You need to measure just under your breasts, making sure that no breast tissue is included in the measurement.

Note down the measurement on a piece of paper. Now add 5 to this number to arrive at the numerical part of your bra size. If the number you get after adding 5 is odd, add 1 to it to arrive at the next even number. For instance, if your ribcage measurement is 29 inches, your Band Size Measurement will be 34 (29 +1). At the same time, if your ribcage measures 30 inches, your Band Size Measurement will be 36 (30 + 5 + 1).

Cup Size Measurement

To get the right cup size, you need to measure your breast with a tape. While taking the measurement, make sure that you hold the tape over the fullest part of your breasts. We will call this measurement the Breast Measurement. For most women, this will be over the nipples. Do not press or tighten the tape. Also make sure that the tape does not bend downwards behind your back. So it is advisable to stand before a mirror while taking the measurement. After you hold the tape around your breasts, look at yourself in the mirror (both front and back) to make sure that the tape is in correct position and is over the fullest part.

Note the measurement on the paper. Now to get the cup size, you need to subtract the band measurement from the breast measurement. The difference will give you your cup size as given in the chart below.

Difference (Breast Size minus Band Size) Cup Size

0 to 1/2 inch : AA
1/2 to 1 inch : A
1 to 2 1/2 inches : B
2 1/2 to 3 1/2 inches : C
3 1/2 to 4 1/2 inches : D
4 1/2 to 6 inches : DD (E)
6 to 7 inches : DDD (F)
7 to 8 inches : G


Let's assume your frame size is 30 inches, your Band Size is therefore 36 inches (30 + 5 + 1 = 36 inches). If you measured your Breast Size at 40 inches, take your Breast Size (40), and subtract your Band Size (36). You get 4 inches as the difference. Using the table above, you find that anyone with a difference between 3 1/2 to 4 1/2 inches (including 4) has a cup size D. Your correct bra and cup size is therefore 36 D.

Hopefully, this article will make bra size measurement easy for you. Happy Bra Shopping!!!
