How Do You Measure For a Nursing Bra: A Complete Guide for New Mothers

Every new mother should find the perfect nursing bra. A good nursing bra not only helps to give you a bit of comfort in the changing times but it also helps to support your changing body during your pregnancy and while breastfeeding. There are so many sizes it can be a bit overwhelming to know what size you should get. In this detailed guide, I will walk you step by step through the process of getting a nursing bra measured correctly to get a nursing bra fit that both physically supports you as well as the breastfeeding journey.

1. Why Properly Measuring for a Nursing Bra is Essential

The first is not understanding why a well fitted nursing bra matters to you. There are big changes in a woman’s breast as a result of pregnancy and childbirth. Not only will your breasts enlarge, but even their shape and fullness will fluctuate due to hormonal shifts and milk production. During this period, an ill fitting bra could cause you discomfort, back pain, and skin irritation.

A nursing bra that fits correctly will:

• Support your changing breast size as it increases during pregnancy and after birth.
• Make breastfeeding more comfortable by featuring easy-to-release clasps and breathable material.
• Prevent discomfort such as chafing or clogging of milk ducts caused by poor fit.

A proper fit is key to ensuring that you stay comfortable, both physically and emotionally, as you adjust to motherhood.

2. When Should You Measure for a Nursing Bra?

The ideal time to measure for a nursing bra is toward the end of your pregnancy, ideally around 36 weeks. That said, keep in mind that your breasts will continue to change after childbirth, particularly as milk production ramps up. This is why it’s advisable to buy two nursing bras initially: one for the final stages of pregnancy and another for when your milk comes in.

Once breastfeeding becomes more established (usually a few weeks after delivery), you can reassess your size and purchase additional bras to fit your body as it continues to change.

3. A Simple Step-by-Step Guide to Measuring for a Nursing Bra

Finding the correct size for a nursing bra is simple, but accuracy is key. To start, you’ll need a soft measuring tape and a non-padded bra that fits well. Here’s how to measure properly:

Step 1: Measuring Your Band Size

How to Measure:

1. Stand upright and relax your body.
2. Place the measuring tape around your ribcage, directly beneath your bust.
3. Make sure the tape is parallel to the floor and tight enough that it doesn’t come loose and doesn’t slip too easily.
4. Record the measurement in inches, rounding to the nearest whole number.
5. If the result is an even number, add 4 inches. If it’s odd, add 5 inches.

• Example:
  If you are 29 inches in your ribcage, your band size may be 33 inches (29 + 4).

Step 2: Measuring Your Bust Size

How to Measure:

1. Stand in front of a mirror with your arms relaxed.
2. Place the measuring tape round your fullest bust, over your nipples.
3. Place the tape snug, but not too tight, and it should be perfectly level around.
4. Record this measurement in inches.

• Example:
  If your bust measurement is 36 inches, and your band size is 33 inches, the difference is 3 inches, which corresponds to a C cup.

Step 3: Determining Your Cup Size

Cup Size Chart:

• 1-inch difference = A cup
• 2-inch difference = B cup
• 3-inch difference = C cup
• 4-inch difference = D cup
• 5-inch difference = DD/E cup

Note: Keep in mind that cup sizes can vary by brand, so it’s always a good idea to try on the nursing bras to make sure they fit as expected.

4. Common Mistakes When Measuring for a Nursing Bra

Avoid these common errors when measuring for a nursing bra:

• Measuring Over a Padded Bra: Always use a non-padded bra to get the most accurate measurement.
• Pulling the Tape Too Tight: It should be tight enough, but not tight. You should be able to get a finger underneath it easily.
• Not Re-measuring: Your breast size can fluctuate, so make sure to recheck your measurements periodically.
• Forgetting to Account for Postpartum Changes: After giving birth, your breasts will swell as your milk comes in. Be prepared for this change when purchasing bras.

5. Selecting the Right Style of Nursing Bra

After you have your measurements, it’s time to decide which style of nursing bra will work best for you. Here are the most common types:

Wireless Nursing Bra

• Pros: Comfortable and flexible, ideal for daily wear.
• Cons: May not offer sufficient support for those with larger breasts.

Underwired Nursing Bra

• Pros: Provides excellent support, especially for women with fuller breasts.
• Cons: Can be less comfortable for long wear and may irritate the skin.

Sports Nursing Bra

• Pros: Offers great support for active mothers.
• Cons: Can be bulkier and less stylish.

Sleep Nursing Bra

• Pros: Soft and comfortable, perfect for nighttime wear.
• Cons: Provides less support than other styles.

Convertible Nursing Bra

• Pros: It’s also versatile it can be used as either a normal or as a nursing bra.
• Cons: Typically more expensive than other options.

6. How to Ensure Your Nursing Bra Fits Properly

Even with the right measurements, the bra may not always feel perfect at first. Here’s how to check the fit:

• Band Fit: The band should sit securely around your ribcage and stay in place when you raise your arms. It should lie flat across your back.
• Cup Fit: The cups should completely encase your breasts without any overflow, and there should be no gaps between your breast and the fabric.
• Strap Fit: The straps should rest comfortably on your shoulders without digging into your skin.
• Closure Fit: If you’re in the late stages of pregnancy or postpartum, choose a bra with multiple hook options to accommodate your fluctuating size.

7. Caring for Your Nursing Bra

To ensure your nursing bras last as long as possible, proper care is essential:

• Hand wash your bras whenever possible to preserve the fabric.
• If using a machine, place bras inside a laundry bag to prevent damage.
• Air dry your bras instead of using a dryer, as heat can damage the elastic.
• Rotate your bras to avoid over-wearing the same one, which can lead to quicker wear and tear.

Conclusion: The Importance of a Well-Fitting Nursing Bra

Choosing the right nursing bra is about more than just picking a size it’s about comfort, support, and practicality. By carefully measuring your body and choosing a style that suits your needs, you can make your breastfeeding journey smoother and more comfortable.
