1. What is Bra Cup Size?

Bra cup size represents the difference between your bust measurement and your band measurement. It's a letter designation (A, B, C, etc.) that indicates the volume of the breasts relative to the band size.

2. How Does the Calculator Work?

The calculator uses the standard bra sizing formula:

Where:

• \( Bust \) — Measurement around the fullest part of the bust (inches)
• \( Band \) — Measurement under the bust, on the ribcage (inches)

Explanation: The difference between these two measurements determines your cup size according to standard sizing charts.

3. Importance of Correct Bra Size

Details: Wearing the correct bra size is important for comfort, posture, and breast support. An ill-fitting bra can cause back pain, shoulder grooves, and other discomforts.

4. Using the Calculator

Tips:

• Measure your bust at the fullest part while wearing a non-padded bra
• Measure your band snugly under your bust
• All measurements should be in inches
• Round to the nearest 0.5 inch for most accurate results

5. Frequently Asked Questions (FAQ)

Q1: How often should I measure my bra size?
A: It's recommended to measure every 6-12 months, or after significant weight changes, pregnancy, or breastfeeding.

Q2: Why do bra sizes vary between brands?
A: Different manufacturers may have slightly different sizing standards. Always check the brand's specific size chart when possible.

Q3: What if my measurement falls between sizes?
A: Try both sizes to see which fits better. The band should be snug but comfortable, and the cups should fully contain breast tissue without gaping or spillage.

Q4: Should I measure myself or get professionally fitted?
A: While self-measurement works well, a professional fitting can be more accurate, especially for difficult-to-fit shapes.

Q5: How tight should the band measurement be?
A: The measuring tape should be snug against your skin but not constricting. It should stay in place without digging in.
