Bra Size Calculator: How to Calculate Your Bra size

As a woman, one of my consistent struggles is keeping track of my bra size.

It seems that by a certain age that a woman would know her own bra size, but your bra size can change depending on the brand and the various styles that the brand may make (such as strap-less, balconette, etc.).

It is even advised to get your bra measurements taken once a year due to how styles, as well as your body, change.

Aging, hormone fluctuations, pregnancy, weight loss or gain, and stress are factors that can result in changes in your breasts.

When considering the various brands of lingerie and bras available, sizes may run differently. For instance, one brand’s DDD-cup may be smaller than the next brand’s DDD-cup.

Unless I decide to have my measurements taken every time I go bra shopping, I’m usually playing a guessing game on my size. How many can relate?

Learning how to efficiently calculate your bra size will be beneficial in the long run for a few reasons.

Bra Size Calculator

The bra size calculator estimates your bra size according to your band (frame) and bust sizes:

What's your band/frame size? This is the firm circumference directly underneath the breast (measured at a close fit – not tight!).
What’s your bust size? This is the loose circumference around the chest at the fullest part of your breasts (wear a properly fitted bra to get a proper measurement while standing straight with your arms to your side).
What’s your bra cup size? This is the difference between your band and bust size.

How to Measure the Bra Size Calculator

You will need a measuring tape to measure around your torso directly under your bust where the bra band would sit. Make sure the tape is level and snug.

For the most accurate measurements, measure to the nearest ¼ inch or ½ cm.

How will you know when you’ve found the perfect bra size?

There are a few signs that indicate that you may not have found the right, let alone perfect, size bra.

Your breasts should not spill over the sides or middle of the bra.
“Double breasts” should not form between the cups.
The cups of your bra should not be loose; they should enclose the whole breast.
The band around your body should not be pulled up at the back and should form a straight line at the bottom.
The shoulder straps of your bra should not dig into your skin, and you should be able to comfortably place your finger between your shoulder and the strap.

Why You Should Have a Professional Bra Fitting

If all else fails with your ability to determine your true bra size, having a professional bra fitting will be best.

Whether you’ve had a professional fitting many times or later in your life, you will be amazed by the results of being fitted with the perfect bra.

The professional fitters can assist you with any problems you have had with choosing the right size bra on your own, as well as introduce you to the best bras that work best for your shape and figure.

Go to your local lingerie boutique or specialty store to get your bra fitting so you can start bra shopping the proper way.

In the end, not only do you save yourself from an improper-looking outfit, but also from any back and breast pains that may come with consistently wearing an ill-fitted bra; this especially holds true for women with larger breasts.
