Bra Size Calculator
Find your estimated bra size by accurately measuring your under bust and fullest bust. Use a soft measuring tape and ensure it's snug but not tight.
Understanding Bra Sizing
Finding the right bra size is crucial for comfort, support, and the overall look of your clothing. Many women wear the wrong size, leading to discomfort and poor posture. This calculator provides an estimate based on standard US/UK sizing conventions.
How to Measure Accurately:
- Under Bust Measurement (Band Size): Stand upright without a bra or in a non-padded bra. Wrap a soft measuring tape snugly around your rib cage, directly under your bust. Ensure the tape is level all the way around and exhale fully to get the smallest measurement. This measurement helps determine your band size.
- Fullest Bust Measurement (Cup Size): While still standing upright, wrap the measuring tape around the fullest part of your bust (usually across the nipples). Make sure the tape is level and not too tight or too loose.
What Do the Numbers and Letters Mean?
- Band Size (e.g., 32, 34, 36): This is the number part of your bra size. It corresponds to your under bust measurement and indicates the circumference of the bra band. A well-fitting band provides most of the support.
- Cup Size (e.g., A, B, C, D): This is the letter part of your bra size. It's determined by the difference between your fullest bust measurement and your band size. Each inch of difference typically corresponds to an increase in cup letter.
Important Considerations:
Bra sizing is not an exact science, and there can be variations between brands and styles. This calculator provides a starting point. Always try on bras to ensure the best fit. Look for a band that is snug and level, cups that don't gap or overflow, and straps that don't dig into your shoulders.
Factors like breast shape, breast density, and personal preference can also influence the ideal bra size. Don't be afraid to try sister sizes (e.g., a 34B might fit similarly to a 32C or 36A) if your calculated size doesn't feel quite right.
