1. What is Bra Size Calculation?

Bra size is determined by two measurements: the band size (underbust measurement) and the cup size (difference between bust and underbust measurements). A proper fit is essential for comfort and support.

2. How Does the Calculator Work?

The calculator uses standard bra sizing formulas:

Where:

• Band size is rounded to the nearest even number
• Cup size is determined by the difference between bust and band measurements
• Each inch difference corresponds to a cup size (1" = A, 2" = B, etc.)

Explanation: The calculation accounts for both the ribcage measurement and breast volume to determine the optimal bra size.

3. Importance of Proper Bra Sizing

Details: Wearing the correct bra size improves comfort, posture, and breast support. Ill-fitting bras can cause back pain, shoulder grooves, and poor breast shape.

4. Using the Calculator

Tips: Measure snugly under your bust for band size and around the fullest part of your bust without compressing. Measurements should be in inches.

5. Frequently Asked Questions (FAQ)

A: Different brands use slightly different sizing systems. Always check the brand's specific sizing chart.

Q3: What if my measurement is between band sizes?

Q5: Should I measure with or without a bra?
A: Measure without a bra for most accurate results, or wear a non-padded bra if you prefer.
