Introduction to Bra Size Measurement

Bra size is determined by two key components: band size and cup size. Band size refers to the circumference of the ribcage, while cup size indicates the difference between the ribcage and bust measurements.

Understanding Bra Size Components

Band Size

Band size is measured around the ribcage, just below the bust. It determines the width of the bra’s band and provides the majority of the bra’s support.

Cup Size

Cup size represents the volume of the breasts and is determined by the difference between the bust measurement and the band measurement. Cup sizes are denoted by letters (e.g., A, B, C) and increase in volume as the letters progress.

Methods for Measuring Bra Size

Using a Measuring Tape

Wear a well-fitting bra (preferably without padding) and stand in front of a mirror.
Use a soft measuring tape to measure the circumference of your ribcage just below the bust, ensuring the tape is snug but not tight.
Record the measurement in inches or centimeters.
Measure the circumference of your bust at the fullest part, keeping the measuring tape parallel to the ground.
Subtract the band measurement from the bust measurement to determine cup size.

Using a Bra Size Calculator

Alternatively, you can use an online e2-e4.tv/ calculator that takes your measurements and calculates your bra size automatically. Many lingerie retailers offer bra size calculators on their websites for convenience.

Tips for Accurate Bra Size Measurement

Wear a Well-Fitting Bra

Ensure you’re wearing a bra that fits well and provides minimal padding or shaping to obtain accurate measurements.

Take Measurements When Standing Up

Stand up straight with your arms at your sides to ensure proper posture and accurate measurements.

Measure Underbust and Bust Circumference

Measure both the circumference of your ribcage under the bust and the circumference of your bust at the fullest part for comprehensive bra size calculation.

Determining Bra Size

Calculating Band Size

Use the measurement of the ribcage circumference under the bust to determine the band size. Round up to the nearest whole number to find your band size.

Calculating Cup Size

Subtract the band measurement from the bust measurement to determine the cup size. Each inch of difference corresponds to a cup size (e.g., 1 inch = A cup, 2 inches = B cup).

Conclusion

Finding the right bra size is essential for comfort, support, and confidence. By understanding the components of bra size, utilizing accurate measurement methods, and following helpful tips, you can ensure a perfect fit and enjoy the benefits of a well-fitting bra.
