Bra Size Formula:
From: | To: |
Bra size calculation determines the proper fit for a bra based on body measurements. It consists of a band size (number) and cup size (letter) that together provide optimal support and comfort.
The calculator uses standard bra sizing formulas:
Where:
Explanation: The band size provides the foundation of support while the cup size accommodates breast volume.
Details: Proper bra sizing is crucial for comfort, posture, and breast health. Ill-fitting bras can cause back pain, shoulder grooves, and tissue damage.
Tips: Measure while wearing a non-padded bra. Take underbust measurement snugly and bust measurement loosely at fullest part. Measurements should be in inches.
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 measurement falls between sizes?
A: Try both sizes - different brands may fit differently. The band should be snug but comfortable on the loosest hook.
Q3: When should I remeasure?
A: After significant weight changes (gain/loss of 10+ lbs), pregnancy, or every 6 months as bras stretch over time.
Q4: Why does my calculated size differ from what I usually wear?
A: Many women wear incorrect sizes due to outdated sizing methods or store fitting practices. Trust your measurements.
Q5: Are there different sizing systems?
A: Yes, this calculator uses US/UK sizing. European and Australian sizes use different numbering systems.
