The Ultimate Guide To Measuring Your Bra Size At Home

There are many reasons you may opt for breast surgery and whether you are choosing breast enlargement or reduction, size and shape are common factors for both. But did you know that you can adjust the appearance of your breasts by simply wearing a correctly fitted bra?

This may sound simplistic and obvious, but many people wear poorly fitting bras without knowing. This can cause breasts to appear smaller or larger than they are and can alter the shape and how they look in clothing.

Before you take the plunge, investing in a perfectly fitted bra can help you properly assess what you’re already working with, making an informed decision on what changes you want. This includes how many cup sizes you want to increase or decrease and whether you want a lift.

First things first, you’ll need a tape measure. A soft, fabric one is preferable and will be easier to use and more comfortable than metal or plastic options. You’ll likely have one in any sewing kit you have handy. 

You will want to measure your band size. This is the measurement taken under the bust and around your rib cage. Stand upright without a bra on and straighten your back and measure around your back and under your breasts where your band usually sits. 

This measurement should be snug, but not too tight, as you want to be supported but still comfortable. Most bras have elastic in the band so there will be some extra give, but if your measurement is an odd number, round up to the nearest even number, not down. 

Cup size comes next. This measurement is taken around the fullest part of the breast. This differs from person to person and while for some it may be at nipple level, for others it may be above or below. 

The best way to find your perfect size is to wear a bra that holds your breasts comfortably in a place you are happy with and take the measurement then. Make sure you don’t wear a padded bra though, as this could increase the cup size and give you poor measurements. 

Once you have this measurement, you’ll want to subtract your band measurement from it. The difference between the two numbers will give you your cup size. 

For example: 

AA = 0in

A = 1in

B = 2in

C = 3in

D = 4in

DD = 5in 

And so forth. 

If your band measurement was 32in and your bust measurement was 36in, you would do 36 minus 32, giving you 4. 4=D, therefore your bra size would be a 32D. 

This is the standard, textbook size of your correct fitting bra. However, there are always going to be some differences between individuals, the type of bra you wear, the brand of bra you wear and the material of the bra itself. 

Therefore, not every bra in your ‘size’ will fit perfectly. Finding the best style and fit for you is unfortunately down to trial and error. You may want to try sister sizes and see if you are more comfortable in a slightly bigger or smaller band and cup size.
