Use this calculator to estimate your bra size based on your measurements. While this provides a good starting point, remember that bra sizing can vary between brands, and a professional fitting is always recommended for the best results.

Understanding Your Bra Size for Victoria's Secret
Finding the perfect bra can be a game-changer for comfort, support, and confidence. While Victoria's Secret is a popular brand, their sizing can sometimes feel a bit different from other retailers. This calculator aims to give you a good estimate of your size, keeping in mind general bra sizing principles.
How to Measure Yourself Accurately
Underbust Measurement (Band Size): Stand upright and wrap a soft measuring tape snugly around your rib cage, directly under your bust. Make sure the tape is level all the way around and exhale to get the smallest measurement. This measurement helps determine your band size.
Bust Measurement (Cup Size): Wrap the measuring tape loosely around the fullest part of your bust, usually across your nipples. Ensure the tape is level and not too tight or too loose.
It's best to wear a non-padded bra or no bra at all when taking these measurements for the most accurate results.
How the Calculator Works
Our calculator uses a common method for determining bra size:
Band Size: Your underbust measurement is rounded to the nearest whole number, then adjusted to the nearest even number. For example, if your underbust is 29 inches, your band size will be 30. If it's 30 inches, your band size will be 30.
Cup Size: The difference between your bust measurement and your underbust measurement (before rounding for the band) determines your cup size. Each inch of difference corresponds to a cup letter (e.g., 1 inch = A, 2 inches = B, 3 inches = C, and so on).
Victoria's Secret Sizing Nuances
Historically, some bra sizing methods, including those sometimes associated with Victoria's Secret, involved adding 4 or 5 inches to your underbust measurement to get your band size. However, modern and more accurate fitting practices generally recommend using your true underbust measurement (or rounding to the nearest even number) for the band. Victoria's Secret's size range can also be more limited compared to specialty bra boutiques, often focusing on common sizes. If your calculated size falls outside their typical offerings (e.g., very small bands or very large cups), you might find their selection limited.
Important Considerations
Sister Sizes: If your calculated size isn't comfortable or available, you might try "sister sizes." For example, a 34B has a similar cup volume to a 32C or a 36A. Going down a band size means going up a cup size to maintain similar volume, and vice-versa.
Fit is Key: The numbers are just a starting point. A well-fitting bra should have a band that is snug and level around your back, cups that fully encapsulate your breasts without gaping or spilling, and straps that provide support without digging in.
Professional Fitting: For the most accurate and comfortable fit, especially if you're unsure, consider getting a professional bra fitting at a lingerie store.
Examples:
Let's look at a few examples using the calculator's logic:
Example 1:
Underbust: 30 inches
Bust: 35 inches
Calculation: Band = 30 (30 rounded to nearest even). Cup difference = 35 – 30 = 5 inches.
Result: 30DD
Example 2:
Underbust: 29 inches
Bust: 34 inches
Calculation: Band = 30 (29 rounded to nearest even). Cup difference = 34 – 29 = 5 inches.
Result: 30DD
Example 3:
Underbust: 32 inches
Bust: 33 inches
Calculation: Band = 32 (32 rounded to nearest even). Cup difference = 33 – 32 = 1 inch.
Result: 32A
