Victoria’s Secret Bra Fit Calculator
Your guide to finding the perfect bra fit from the comfort of home.
This calculator determines your band size by rounding your under-bust measurement to the nearest even number. The cup size is found by subtracting your band measurement from your bust measurement.

Sister sizes have the same cup volume. If your band feels too loose or too tight, try a sister size.
What is a Victoria’s Secret Bra Fit Calculator?
A Victoria’s Secret Bra Fit Calculator is a specialized online tool designed to help you determine your most accurate bra size based on your unique body measurements. Unlike generic calculators, this tool uses a fitting method aligned with the sizing and styles you’ll find at Victoria’s Secret. The primary goal is to eliminate the guesswork and discomfort of wearing an ill-fitting bra by providing a reliable starting point for your size.
Anyone who wears a bra, from teens experiencing their first fitting to adults whose bodies have changed over time, can benefit from using a Victoria’s Secret Bra Fit Calculator. It’s particularly useful if you’ve been wearing the same size for years, have recently experienced weight changes, or are post-pregnancy. A common misconception is that your bra size stays the same forever, but experts recommend remeasuring every 6-12 months. Using this calculator is the first step towards better support and comfort.
Victoria’s Secret Bra Fit Calculator: Formula and Mathematical Explanation
The logic behind the Victoria’s Secret Bra Fit Calculator is straightforward and focuses on two key measurements. The process ensures you find a balance between band support and cup capacity.
Step 1: Determine Band Size. Measure your ribcage directly under your bust (Underbust). This raw number is rounded to the nearest even number to get your final band size. A snug band provides over 80% of a bra’s support.
Step 2: Determine Cup Size. Measure the fullest part of your bust. The difference between this bust measurement and your *original underbust measurement* determines your cup letter. Each inch of difference corresponds to a cup size (1″ = A, 2″ = B, etc.).
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Underbust (U) | Measurement around the ribcage, just below the bust. | Inches | 26 – 48 |
| Bust (B) | Measurement around the fullest part of the bust. | Inches | 28 – 55 |
| Band Size | The numeric part of your bra size (e.g., 34). Calculated from U. | Standard Size | 30, 32, 34, … |
| Cup Difference | The result of (B – U). Determines the cup letter. | Inches | 1 – 10 |
Practical Examples (Real-World Use Cases)
Understanding the Victoria’s Secret Bra Fit Calculator is easiest with examples.
Example 1: Average Measurements
- Inputs:
- Band Measurement (Under Bust): 31 inches
- Bust Measurement: 36 inches
- Calculation:
- Final Band Size: 31 inches is odd, so we round up to 32.
- Cup Difference: 36 (Bust) – 31 (Underbust) = 5 inches.
- Cup Size: A 5-inch difference corresponds to a DD cup.
- Output: 32DD. This indicates the need for a bra with a snug 32 band and a cup volume designed for a 5-inch projection. For more style options, check our full bra collection.
Example 2: Fuller Bust
- Inputs:
- Band Measurement (Under Bust): 34.5 inches
- Bust Measurement: 41 inches
- Calculation:
- Final Band Size: 34.5 is rounded to the nearest even number, 34.
- Cup Difference: 41 (Bust) – 34.5 (Underbust) = 6.5 inches. We round to the nearest whole number, 7.
- Cup Size: A 7-inch difference corresponds to a G cup.
- Output: 34G. This size requires significant support from the band and full-coverage cups. Our expert fitting guide has more tips.
How to Use This Victoria’s Secret Bra Fit Calculator
Using our Victoria’s Secret Bra Fit Calculator is simple. Follow these steps for an accurate result:
- Enter Band Measurement: Use a soft tape measure. Make sure it’s snug and level across your back. Enter the number in the first input field.
- Enter Bust Measurement: Measure around the fullest point of your bust. The tape should be looser here, not compressing your chest. Enter this in the second field.
- Read Your Results: The calculator instantly displays your estimated bra size. Note the primary result and the intermediate values like cup difference.
- Consider Sister Sizes: The table shows your sister sizes. If a bra in your calculated size feels too tight in the band, try the sister size up (e.g., from 34C to 36B). If the band is too loose, try the sister size down (e.g., from 34C to 32D).
Key Factors That Affect Victoria’s Secret Bra Fit Calculator Results
Several factors can influence your fit. Being aware of them helps you choose the right bra even after using the Victoria’s Secret Bra Fit Calculator.
- Bra Style: A plunge bra, a full-coverage bra, and a balconette bra in the same size will fit differently. Some styles, like our Perfect Shape collection, offer more structure.
- Brand Inconsistencies: Sizing can vary slightly between brands. Always use the brand-specific calculator when possible.
- Time of the Month: Hormonal fluctuations can cause breasts to swell, affecting your size. It’s best to measure when you feel your breasts are at their “normal” size.
- Weight Changes: Gaining or losing even a few pounds can alter your ribcage and bust measurements, requiring a new fitting.
- Band Elasticity: Over time, a bra’s band will stretch out. A new bra should fit snugly on the loosest hook, allowing you to tighten it as it ages.
- Breast Shape: Shape (e.g., round, slender, teardrop) affects how you fill a cup. Some shapes fit better in certain styles regardless of the size calculated by a Victoria’s Secret Bra Fit Calculator.
Frequently Asked Questions (FAQ)
It’s recommended to remeasure your bra size every 6-12 months, or after any significant life event like pregnancy or weight change, using a reliable tool like this Victoria’s Secret Bra Fit Calculator.
Gaping cups usually mean the cup size is too big. Try going down a cup size (e.g., from C to B). It can also mean the band is too loose and not pulling the cups flat against your body. If you have questions, feel free to contact our fit experts.
Spillage (when your breasts bulge out of the top or sides of the cup) means the cup size is too small. You should go up one or more cup sizes.
This is an older method where you add 4 or 5 inches to your underbust measurement to find the band size. Most modern brands, including Victoria’s Secret, do NOT use this method anymore as it often results in a band that is too loose and cups that are too small. This Victoria’s Secret Bra Fit Calculator uses the modern, direct measurement method.
Sister sizes offer flexibility. They allow you to find the same cup volume on a different band size. For example, a 32D has the same cup volume as a 34C and a 36B. This is crucial when a certain style’s band runs tight or loose.
While this calculator gives you a great starting bra size, sports bras often use more general S/M/L sizing. However, knowing your precise size (e.g., 34D) helps you find the correct corresponding size on a sports bra chart. Look for our T-Shirt Bras for everyday comfort.
If you’re between sizes, consider the bra style. A lined or padded bra may require you to size up, while an unlined, stretchy style might fit better in the smaller size. Trying on both is the best approach.
Not always. Wireless bras can be more forgiving in fit, but might offer less separation and support. Your size from the Victoria’s Secret Bra Fit Calculator is the right starting point, but you may prefer a snugger band in a wireless style for better support.
