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). Proper fitting is essential for comfort and support.

2. How Does the Calculator Work?

The calculator uses standard bra sizing formulas:

Where:

• \( Underbust \) — Measurement around the ribcage just below the bust (inches)
• \( Bust \) — Measurement around the fullest part of the bust (inches)
• \( Band \) — Rounded to nearest even number
• \( Cup \) — Letter representing the difference between bust and band measurements

Explanation: The band provides support while the cup accommodates breast volume. Accurate measurements ensure proper fit.

3. Importance of Proper Bra Sizing

Details: Wearing the correct bra size prevents discomfort, back pain, and poor posture. Many women wear incorrectly sized bras without realizing it.

4. Using the Calculator

Tips: Measure underbust snugly but not tight. Measure bust while wearing a non-padded bra. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why round to even numbers for band size?
A: Bra bands typically come in even-numbered sizes for standardization and manufacturing purposes.

Q2: What if my cup size isn't available?
A: Some brands offer extended sizing. Consider sister sizing (adjust band up/down with opposite cup change).

Q3: When should I remeasure?
A: After significant weight changes, pregnancy, or every 6-12 months as body composition changes.

Q4: Are there limitations to this calculation?
A: Body shape, breast density, and brand variations can affect fit. Always try before buying when possible.

Q5: Should I measure myself or get professionally fitted?
A: Both methods have value. Professional fittings can account for nuances self-measurement might miss.
