When you have large breasts and are plus-sized, it is nearly impossible to find a supportive, comfortable bra. Shopping for said “miracle bra” that actually fits correctly and is semi-cute can be flat out exhausting, so it is crucial to know your actual bra size prior to your search.

According to a study done by inclusive lingerie brand Third Love, only 20 percent of women are wearing the correct cup size, and most go through their whole adult lives wearing the wrong size bra. I myself have been guilty of wearing undergarments that dig into my shoulders and don't fully support me until I finally measured myself and began buying the correct size. Not all brands fit the same, which is why it is extremely important to know your measurements so you can compare with a brand’s own sizing guide.

Insider Sizing Tips

Though there is no real foolproof bra calculator, I have provided a simple outline and rule of thumb, below, to help you determine your correct bra size at home.

All you need is a soft measuring tape and two measurements: the band size, which can be found around your back and under your bust, and the cup measurement, which can be found by measuring around your back and over your nipples. After you have these two numbers you will subtract your band size from your cup size and that difference will correspond to you specific letter cup.

For example, my band size is 44 inches and my cup size is 51 inches, which means 51- 44 = 6, which equals a DDD, according to the below guide.

Easy Cup Size Measure Guide:

1''= A

2''= B

3''= C

4''= D

5''= DD

6''= DDD & F

7''= G

8''= H

9''= I

10''= J

11''= K

Once you have measured your perfect size, it’s time to make sure that your bra is fitting the way it is meant to be worn.

The Band

Most people are surprised to learn that the band is the main support feature to your whole bra and that, when your band fits as it’s intended, then you will actually get the large bust support you need. A quick test to determine if your band fits or not is this: If you cannot fit a finger between the bra band and your skin, it’s too tight. And if there are gaps at the bottom of the cup, then it’s too loose and the bra will inevitably ride up.

Expert Tip: When you buy a new bra, clip it to the loosest row of hooks so that when the bra stretches from washing and wear, you can size down.

Center Gore

The center gore is the little area between the breast cups and the skin. This area of the bra should remain tighter to the skin to keep your breast from slipping out the bottom. If you can stick a finger between the center gore that means that it is too loose and will not provide the necessary support.


When appraising whether or not your cup size is correct, the cups should appear full and smooth. Often when they are too large there will be empty spots and have pockets in the fit. If the cup size is too small you will notice spillage under your arms or over the top and you need to size up accordingly. Next, you need to check if the fit of the underwire stays flat against your skin and doesn’t pinch or poke.


A bra with adjustable straps that you can loosen and tighten on demand, depending on the amount of wear, is key. Your bra straps should fit comfortably on your shoulder without digging and pinching or creating a tight red imprint when you take it off. The straps should also stay in place and not slip off your shoulders when you wear them, which typically indicates the bra is too large or the bra has lost its elasticity and it’s time to get a new one.
