Complete Guide To Nursing Bra Sizing

Bra shopping is confusing. Let us help you.

Bra shopping is hard enough before you’re pregnant, but pregnancy and nursing boobs add a whole new set of complications. We see you. We hear you. And we’re here to help.

What is the best bra style for me?

Our Comfort Zone Nursing Bra is best suited for cup sizes A - H. Our Body Bra is best suited for sizes A - E/F. The Everyday Bra, Cozy Rib Nursing & Sleep Bra, and Pumping & Nursing Bra Top are best suited for cups A - E. For cup sizes F - H, the Comfort Zone Nursing Bra will offer the best fit. Other bra styles may accommodate but with less support.

The Body Bra offers our most flexible fit to accommodate cup size changes, so one bra can take you from pregnancy through postpartum and beyond.

How to measure my bra size?

To get to this answer, you must, must, must measure. Even if you’ve never worn a “sized” bra in your life, we are here to tell you that your time has come. Getting an accurate picture of your nursing bra size will spare you a lot of poorly-fitting bra grief and a great many online returns down the line. So let us begin:

Step 1 Measure Your Underbust. This is the zone right below the boob. Using a soft measuring tape, wrap the tape only around your ribcage just under your breasts, making sure it’s not wrapped over any of the soft tissue of your breasts. It should be snug but not suffocating you. Make a note of this measurement in inches, and round any fractions up to the next whole number. Great, now you’ve got your band size.

Step 2 Measure The Fullest Part of Your Chest. The measuring tape will go around your back and across your boobs where they are the fullest. This is usually right over your nipples. Try to make sure the tape is sitting level from back to front (aka not dipping down or riding up in the back). Make sure you are not squishing your boobs at all with the measuring tape, let them breathe, and round up any fractions to the next whole number. Boom. This is your bust measurement.

Step 3 Do Some Simple Math (on your phone calculator, of course!). 

Bust Measurement - Band Measurement = Numerical Cup Size 

Round up to a whole number, and you’ve got your Cup Size. Once you have your Cup Size number, you can convert it to the letter equivalent as below. 

1 = A | 2 = B | 3 = C | 4 = D | 5 = DD/E | 6 = DDD/F | 7 = DDDD/G | and so forth

Here’s an example. For a band size measuring 29.5” (round up to 30”) and a bust measurement of 34.25” (round up to 35”) your numerical cup size is 5 which equates to a 30DD.

Once you have your bra size, reference our size chart below to find your Storq size!

What are common problems with bra fit?

1. Bra Too Tight: While nursing, you may experience sudden changes in breast size due to fluctuations in milk production that can lead to engorgement. Wearing a bra that is too tight can cause discomfort, restrict milk flow, and cause clogged ducts or mastitis. Opting for bras with stretchy or adjustable bands can help accommodate these literal ups and downs.

2. Insufficient Support: Breast size and weight can increase during breastfeeding, requiring more support. Bras with wide straps and strong elastic bands can provide the necessary support and prevent discomfort.

3. Poorly Fitted Cups: As milk supply fluctuates, the cup size may change, leading to cups that are too small or too large. Ill-fitting cups can cause spillage, compression, or lack of support. Regularly measuring and reassessing your cup size, and adjusting the straps on your bras as necessary, is essential for maintaining comfort and proper fit.

4. Limited Accessibility for Nursing: Traditional bras may not offer the necessary convenience for breastfeeding or pumping. Nursing-specific bras with easy-access features, such as drop-down cups or clasps, allow for discreet and effortless nursing.
