How Our Bra Size Calculator Works

Our tool is designed to be simple yet precise. To calculate your bra size, you need two key measurements:

1. Band Size (Underbust Measurement): Measure around your rib cage, just under the bust.
2. Bust Measurement: Measure around the fullest part of your bust, ensuring the tape is level.

The calculator uses the following steps:

1. Measure Your Band: Add inches if needed to round to the nearest standard band size.
2. Measure Your Bust: Subtract the band size from the bust measurement to determine the cup size.
3. Determine Bra Size: Combine the band size and cup letter (A, B, C, D, etc.) to get your accurate bra size.

Example:

• Band Size = 34 inches
• Bust Measurement = 38 inches
• Difference = 4 inches → Cup Size D
• Bra Size = 34D

Step-by-Step Bra Measurement Guide

1. Use a Soft Measuring Tape: Avoid rigid rulers or fabric measuring lines.
2. Stand Straight & Relaxed: Do not puff your chest or slouch.
3. Wear a Non-Padded Bra: Ensures accurate measurement of natural shape.
4. Measure Underbust: Tape snug around rib cage, right under your breasts.
5. Measure Bust: Tape around the fullest part of your bust, keeping level.
6. Check the Fit: Compare your measurements with our bra size chart.
7. Adjust for Comfort: Band should be snug, cups full but not tight, straps support but don’t dig in.
