How to Use

  1. 1Measure snug underbust by placing a tape measure level around your ribcage directly under your breast tissue.
  2. 2Measure your full bust at the fullest point with the tape measure parallel to the floor.
  3. 3Estimate your band size by rounding your underbust measurement using local sizing conventions.
  4. 4Find your cup difference by calculating the difference between your bust and band measurements.
  5. 5Finally, click the Calculate button and read the results to find your estimated bra size.

Formula

Cup Difference = Bust - Band

The formula calculates the Cup Difference by subtracting the Band measurement from the Bust measurement. The Band size is a numeric representation of your ribcage measurement, while the Bust measurement is taken at the fullest point of your breasts. The resulting Cup Difference is then used to determine the cup letter according to the size chart.

Example Calculation

Suppose you measure your underbust at 32 inches and your bust at 35 inches. First, calculate the Cup Difference: 35 - 32 = 3 inches. This difference indicates a cup size of C based on standard sizing charts. Thus, your estimated bra size would be approximately 32C, although it may vary slightly depending on the brand.

Understanding Your Results

Bra sizes typically consist of a band size and a cup size. A lower band size with a higher cup difference indicates larger cup sizes, while a higher band size with a low cup difference signifies a smaller cup. Understanding this can help you find a bra that offers the best support and comfort for your body type.

Frequently Asked Questions

How do I measure my bust accurately?

To measure your bust accurately, stand straight and wrap a measuring tape around the fullest part of your breasts, ensuring the tape is parallel to the floor. Keep the tape snug but not tight, and take the measurement in inches.

What if my measurements don't match typical sizes?

If your measurements don’t align with standard sizes, consider trying sister sizes, which involve adjusting the band size up or down while changing the cup size accordingly. This can help you find a better fit.

How often should I measure my bra size?

It’s advisable to measure your bra size at least once a year or whenever you experience significant weight changes or hormonal fluctuations that affect your body shape.

What is a sister size?

A sister size is an alternative bra size that may fit similarly to your regular size. For example, if you wear a 34C, your sister sizes would be 32D and 36B, offering different band and cup combinations.

Can I use this calculator for sports bras?

Yes, while this calculator provides a standard bra size, it can also serve as a guideline for selecting sports bras. However, consider the style and support level you need for physical activities.

Why is it important to wear the right bra size?

Wearing the correct bra size is important because it provides the necessary support, improves posture, and enhances comfort, helping to prevent issues like back pain and skin irritation.

What should I do if my bra feels uncomfortable?

If your bra feels uncomfortable, check your measurements and consider trying a different size or style. Also, ensure that your bra is not too tight in the band or too loose in the cup.

Are there different sizing systems?

Can my bra size change over time?
