Measuring Your Bra (Breast) Size

Measuring Your Bra (Breast) Size

How to correctly measure your bra size


"Around 70% to 85% of UK women wear an incorrect bra size!"

The most common mistake is to choose a bra with a band size that is too large and a cup size that is too small. For example, a 36C bra is incorrectly chosen instead of a 34E bra size.

You could be one of these women! Have you been measured professionally recently?

This is certainly worth doing both before and after your breast enhancement surgery. You will want to know where your starting point is, bearing in mind that breast enhancement surgery usually enables you to go up to 2 cups sizes larger.


Bra Band Size Measurement


It is relatively easy to determine for yourself what bra band size you need. Measure the circumference of your ribcage in inches using a soft tape measure. The measurement should be taken just below the breasts, in the area of the crease; measure all the way around the body. Bra band sizes are available in even numbers of inches 32, 34, 36 etc. So if your measurement is in between band sizes i.e. an odd number, then add 1 to it so that it becomes the next available band size up. For example, if your under bust, chest measurement is 33 inches, then you will need to add 1 inch to round up to the next band size which will be 34 inches.

There is a slight caveat to this rounding, in that some bra fitters recommend women with bigger breasts to round down to the lower band size. This typically applies to women who have a cup size of D or larger who are in between band sizes. So if you have an E cup size, for example, and your under bust, chest measurement is 33 inches, then you may choose a band size of 32 inches, rather than rounding up to 34 inches. This approach is believed to be more comfortable and less prone to back pain caused by supporting larger breasts.


Bra Cup Size Measurement


Cup sizes are more difficult to get right. The actual breast size of a 38D cup is much larger than a 32D. The fact that both are D cups does not matter. There are several ways to measure cup size, however the best way is put a bra on and see if it fits!

First, get a rough idea of what cup size you are. Measure the loose circumference around the chest over the fullest part of the breasts, while standing straight with arms to the side. Measure in inches. This is your bust size measurement. From this measurement, now subtract your under bust, chest measurement taken earlier for your band size measurement. Use your actual measurement rather than any rounded up or down measurement. After subtraction, the number you are left with will be your rough cup size measurement.

Trying On Bras


Having determined your correct bra band size and rough cup size, now try on various bras with those measurements. Also, try on one cup size below and one cup size above what you have measured. If the bra is too small, your bust will double cup. Double cupping or double bubble is where the top of the bra cup appears to be squeezed into the breast and some of the top of the breast bubbles out over the top of the cup. This is because the bra cup size is too small. This is a common problem and many women who wear the wrong bra size exhibit double bubble. If the bra fits correctly, there will be no double bubble and the cup will fit snugly against the surface of the breast. In between the breasts, against the chest bone (sternum), the bra should also fit snugly and should not float away from the surface of the body. Again, if this happens the bra cup size is too small.

From my own personal experience, I had been wearing the wrong bra size for years up until just before my breast enhancement surgery. I though that I was a 32C when in actual fact I was a 30DD! Of course I was pleasantly surprised!

When buying a new bra, you should allow for it stretching over time, particularly across the band measurement. So when you buy it, it should fit you with the straps adjusted near their slackest. When the bra stretches over time, you will then have room for being able to tighten up the straps.


Get Your Bra Measured Professionally For Free


In order to be sure of your bra size, I recommend that are fitted professionally. They use the method described above, in conjunction with experience and a professional eye. You can be measured professionally for free in several high street stores, some of the most popular ones are:

  • Bravissimo

  • Debenhams

  • La Senza

  • Marks & Spencer

One important point to remember is that different bras from different manufacturers may differ in size. The same applies for different styles of bra, even from the same manufacturer. This is fairly standard across the clothing industry; jeans are a good example.


Breast sizes and the British woman


It's official! British women have the largest average cup size of any country in the world.
