Bra Size Calculator: Find Your Fit?

The easiest way to find your bra size right from your bedroom. Put on an unpadded bra, grab your tape measure and let's find your bust and band sizes! Our fit calculator will figure out the rest.

Step 1: Measure Your Band Size

Wrap the tape measure around your back and chest going under the arms so it's snug — not tight — and sitting just above the bustline. Round to the nearest whole number.

Step 2: Measure Your Bust Size

Measure around the fullest part of your bust keeping the tape loose enough that it's not squeezing.

Step 3: Enter Your Measurements

Look For the Signs

If you've ever worn an ill-fitting bra, you know how uncomfortable it can be. Not only does improper fit cause discomfort, but it can also keep you from looking your best.

For the past 100 years we’ve made it our mission to help women find the perfect fitting bra tailored to suit their shape. We encourage women to take advantage of our no questions asked - free shipping, free returns policy. Order multiple sizes to find what works best. Try them on in the comfort of your home and send back whatever doesn’t feel quite right. It’s free--we pay postage.

Not sure your bra is fitting the way it should? If you’ve ever experienced any of the following it’s a safe bet that you can find a better fit:
- Your band leaves painful red marks
- Your underwire pokes you in the chest or under your arms
- Your bra cups have large gaps at the top or they have wrinkles
- Your breast tissue spills out over the top of your cups
- Your band rides up in the back
- Your straps constantly fall off of your shoulders
- Your bra hikes up when you raise your arms
- Your straps dig into your shoulders
If you've never measured yourself for a bra before, don't worry it's easier than you think! All you need is a flexible tape measure. You can normally find them with the sewing supplies at craft stores or online. Next, put on an unpadded bra and follow these steps:
1. Measure your band size by wrapping the tape measure around your back and chest, directly under your arms. It should sit directly above your bustline. Round to the nearest whole number.
2. Measure your bust size by wrapping the tape measure across the fullest part of your bust.
3. Enter both measurements into our size calculator to find your size.
Wrap the tape measure around your chest under your arms just above your bust. Make sure that it’s snug but not tight. Round this number to the nearest whole number to get your band size (so 39 becomes a 40 band size).
Wrap the tape measure around yourself again but this time go across the fullest part of your bust. If you plug your band and bust measurements into the bra fit calculator it will calculate your size. Or calculate your cup size by subtracting your band measurement from your bust measurement.

The difference is your cup size:
- 1 = A
- 2 = B
- 3 = C
- 4 = D
- 5 = DD
- 6 = DDD, or F
- 7 = G
- 8 = H
- 9 = I
- 10 = J
- 11 = K
- 12 = L
Sure, but if you want your bra to fit like it was made for you and be as comfortable as possible, the best thing to do is calculate your bra size by measuring yourself.
Enter your measurements into the bra fit calculator to find the size that’s right for you. Knowing your bra size will make bra shopping a much more pleasant experience.
Knowing how to measure yourself will also help you adjust to changes in your breasts. Gaining or losing weight, pregnancy, and aging can all cause your breasts to change size and/or shape. Read our guide to bra sizes to learn more.

Here is a bra size chart to see all of Glamorise's sizes in order.
Once you get your new bra you’ll need to make some adjustments so that it fits as perfectly as possible. When you put your bra on fasten the hooks in the back on the last set of hooks. Make sure that the band is level all around. You should be able to slip a finger underneath, but no more and no less.

As for the cups, try the bend and scoop. After you fasten the band bend over slightly and with one hand scoop and center your breast tissue into each cup.

Next, adjust the straps. Depending on where they adjust you may need to take your bra off if you can’t reach the back of the straps. Like the band, you should be able to slip a finger underneath the straps, but no more than two.

After everything feels secure, take a look at how it fits. Is the band causing bulges? Are your breasts spilling out of the cups? Raise your arms and make sure that everything stays in place. If anything is off you need to re-evaluate your size or possibly the style of the bra.

Every woman is different, and everyone has her own sense of what feels right. The calculator is only a starting point--you may choose a different size that works better for you. That’s why we encourage you to use our free return policy until you find your perfect fit.
