Accurate measurements are the foundation of a great-fitting bra. We'll guide you through each step.
Step-by-Step Instructions
Measure Your Band Size
Wrap the measuring tape snugly around your ribcage, directly under your bust. The tape should be level and parallel to the floor all the way around.
Tips for accuracy:
- • Keep your arms relaxed at your sides
- • Make sure the tape is snug but not tight
- • Round to the nearest even number (31" becomes 30" or 32")
Measure Your Bust Size
Wrap the tape loosely around the fullest part of your bust. Don't pull the tape tight - let it rest gently against your skin.
Tips for accuracy:
- • Stand up straight with good posture
- • Keep the tape level all the way around
- • Don't compress your bust - keep it loose
Calculate Your Cup Size
Subtract your band measurement from your bust measurement. The difference tells you your cup size.

Important Notes
Your calculated size is a starting point
- • Sizes vary significantly between brands
- • Your shape affects fit as much as size
- • Bodies change - remeasure every 6-12 months
- • Consider sister sizes if the band feels too tight or loose
