How to measure bra size

Posted on

Measuring your bra size accurately is crucial for ensuring comfort, support, and the health of breast tissue. Wearing the right bra size not only improves posture but also minimizes discomfort throughout the day. The process involves measuring both the band size and the cup size, and although it might seem daunting at first, with careful steps, anyone can do it at home with just a measuring tape. Here is a detailed explanation of how to measure your bra size correctly:

1. Gather the Necessary Materials

To measure your bra size, you need a flexible measuring tape. Make sure it’s soft, as this will make it easier to wrap around your body accurately. It’s also helpful to have a notebook and a pen to jot down measurements, and perhaps a mirror to help you ensure that the tape is positioned correctly across your back.

2. Measure Your Band Size

  • Step One: Wear a Non-padded Bra
    To get the most accurate measurements, wear a non-padded bra that doesn’t alter the shape of your breasts. This helps in measuring your natural form without any enhancements or reductions caused by padded or push-up bras.

  • Step Two: Measure Under Your Bust
    Stand straight with your arms at your sides. Wrap the measuring tape around your ribcage, right under your bust. Ensure that the tape is parallel to the ground and snug but not too tight. Breathing normally, pull the tape until it feels secure but comfortable and note this measurement. If you get an odd number, round it to the nearest even number. This measurement is your band size.

3. Measure Your Bust Size

  • Step Three: Measure at the Fullest Part of Your Bust
    Without tightening the tape, wrap it around the fullest part of your bust. Make sure the tape is straight and not too loose or tight. It should align horizontally across your back and over your nipples. Stand naturally and take the measurement. It's crucial that the tape is not compressing your breasts, as this can lead to an incorrect measurement.

4. Calculate Your Cup Size

  • Step Four: Subtract Your Band Measurement from Your Bust Measurement
    The difference between the bust measurement and the band measurement determines the cup size. Each inch represents one cup size up. For instance, a 1-inch difference suggests an A cup; a 2-inch difference suggests a B cup, and so on. Here’s a simple breakdown:

    • 1 inch = A Cup
    • 2 inches = B Cup
    • 3 inches = C Cup
    • 4 inches = D Cup
    • 5 inches = DD or E Cup
    • 6 inches = DDD or F Cup
    • And so forth.

5. Consider Sister Sizing

  • Step Five: Understanding Sister Sizes
    Sister sizing is a technique used when your calculated bra size doesn’t seem to fit correctly. It involves moving up or down a band size while adjusting the cup size in the opposite direction to maintain the volume of the cup. For example, if a 34C is too tight around the band but the cup fits well, you might try a 36B.

6. Try on Bras for the Best Fit

  • Step Six: Try Different Brands and Styles
    Different brands and styles of bras can fit differently even if they are labeled with the same size. It’s important to try on different bras to ensure the measurements work across different styles. Make sure the bra is comfortable, the band is level all around your body, and there's no spilling out of the cups. The center of the bra should lie flat against your chest, and the straps should not dig into your shoulders.

7. Assess the Fit

  • Step Seven: Double-Check the Fit
    Once you have your bra on, lean forward to allow your breasts to fall naturally into the cups, then stand up and adjust the bra straps if necessary. The band should feel snug on the loosest hook to allow for the bra to stretch over time. Double-check by inserting two fingers under the band; if you can do this comfortably, the fit is likely correct.

By following these steps, you can accurately measure your bra size, ensuring that you wear bras that are both comfortable and supportive. Remember that women’s bodies can change over time, so it’s a good idea to measure your bra size at least once a year or after any significant change in your weight or body shape. Properly fitted bras not only enhance the appearance of your outfits but also support your posture and prevent discomfort throughout the day.
