How to Calculate Bra Size
To accurately calculate your bra size, you'll need a few essential tools and a basic understanding of the measurement process. Proper sizing ensures comfort and support, enhancing the fit of your clothes.
Tools Required
A flexible measuring tape and a reliable bra size calculator are essential. The measuring tape should allow you to measure snugly around your torso and bust to ensure accurate readings. Use calculators like those provided on popular websites which support various international sizing standards including US, UK, EU, and more.
Measurement Steps
Start with measuring your band size. Wrap the measuring tape directly under your bust, keeping it parallel to the ground and snug. If this measurement is an even number, add four inches (+4) ; if odd, add five inches (+5) . Record this as your band size.
Next, measure your bust size by placing the tape at the fullest part of your chest, making sure it's snug and parallel to the ground. Subtract the band size from the bust measurement to get the size difference. Use this number in combination with your band size to determine your cup size according to a bra cup size chart.
Using a Bra Size Calculator
Input the band and bust measurements into the bra size calculator. These tools typically require both measurements to provide an accurate bra size estimate and display options suitable for various international sizing standards.
This straightforward method ensures that you find the best fitting bra for your body, leading to improved comfort and support everyday.
How to Calculate Bra Size Accurately
To accurately determine your bra size, follow a two-part measurement process involving the band and the bust. This guide provides a step-by-step approach, ensuring a perfect fit.
Measuring the Band Size
Begin by wearing a lightly-lined or non-padded bra to keep the breast shape natural without added volume. Wrap a measuring tape around your back, ensuring it runs parallel to the ground at band level under the bust. For an accurate measure, the tape should be snug but not tight. Round the measurement to the nearest even number; if it's an odd number, round up to ensure the band fits comfortably.
Measuring the Bust Size
Keep the tape around your back at the same level as when measuring the band. Place it across the fullest part of your chest, generally over the nipples, to capture the maximum circumference of your bust. Round up if the measurement falls on a half-inch to accommodate natural variations in size.
Calculating the Cup Size
The cup size is found by calculating the difference between the bust measurement and the band size. Use the following formula: Cup Size = Bust Measurement - Band Size. Each inch of difference corresponds to one cup size up from AA, following this sequence: AA, A, B, C, D, DD, F, FF, G, GG, H, HH, J, JJ, K.
By precisely measuring and applying these steps, you can confidently identify your correct bra size, enhancing comfort and support.

How to Calculate Bra Size: Practical Examples
Example 1: Standard Measurement
Measure the circumference of your chest just below the bust to get the band size. If this measurement is an odd number, round up to the nearest even number. Next, measure the fullest part of your bust for the bust size. The difference between the bust size and the band size determines the cup size. For every inch of difference, the cup size increases by one letter starting from A. For instance, if the band size is 34 inches and the bust size is 36 inches, the bra size would be 34B, because the difference is 36 - 34 = 2 inches.
Example 2: Adding to Band Size
Some brands recommend adding four inches to an odd number band measurement to get an even number. For example, if the under-bust measures 33 inches, add 4 to make it 37 inches. Round off to the next even number, so it becomes 38 inches for the band size. If the bust size is 40 inches, the difference is 40 - 38 = 2 inches. Hence, the calculated bra size is 38B.
Example 3: Large Bust Adjustment
For individuals with a significantly larger bust, measuring technique remains consistent but consider a firmer fit to provide adequate support. If the under-bust measurement is 36 inches (rounded to an even number already) and the bust measurement is 43 inches, the difference in inches is 43 - 36 = 7. This corresponds to a G cup, making the size 36G.
Example 4: Using Sister Sizes
Sister sizes are a useful concept when the calculated size seems off. For example, if 34C feels slightly tight, you can try 36B. Both have the same cup volume. Similarly, if 34C feels loose, try 32D. Adjusting the band size while maintaining cup volume allows for a personalized fit.

Frequently Asked Questions
How do I measure my band size for a bra?
Measure your band size by standing without a bra and measuring around your back and under your bust where the band sits, ensuring the measuring tape is snug and level all the way around. The band size should be a comfortable, even number.
How is the cup size determined in bra sizing?
The cup size is determined by subtracting the ribcage (band) measurement from the measurement around the fullest part of your bust. The difference in inches corresponds to the cup size, represented by letters (A-K).
Why do bra sizes vary across different brands?
Bra sizes can differ from brand to brand due to variations in sizing standards and bra style designs. It's recommended to check the sizing chart of each brand or get professionally fitted to find the best size.
How often should I re-measure my bra size?
It's recommended to get a bra fitting or re-measure your bra size every six months to a year, as your size may change due to various factors like weight changes, hormonal fluctuations, or aging.
What should I do if my bra band rides up in the back?
If your bra band rides up in the back, it usually means the band is too large. Measure the underband tighter and consider choosing a bra with a smaller band size and possibly a larger cup size for a better fit.
Conclusion
Accurately calculating your bra size ensures a perfect fit and comfort. Simple measurements around your bust and underbust provide the necessary data. Typically, the bra size is comprised of a number (band size) and a letter (cup size), calculated from the difference between these measurements.
