Find Your Perfect Bra Size

8 out of 10 women wear an incorrect bra size, leading to back pain, shoulder digging, and slipping straps. Follow our step-by-step measurement guide to calculate your true band and cup size.

1Determines Band Size (80% Support)

Step 1: Measure Your Snug Underbust

Wrap a soft measuring tape directly around your ribcage, directly beneath your breasts where the bra band sits. Keep the tape completely level and snug against your body. Exhale naturally before noting the measurement.

Snug Underbust (Ribcage)
💡 Pro Tip: Do not pull the tape so tight that it pinches, but ensure it does not sag in the back.
2Determines Cup Volume

Step 2: Measure Across Fullest Bust

Wear an unpadded or lightly lined bra. Wrap the measuring tape around the fullest part of your bust (across the nipples). Keep the tape parallel to the floor, holding it comfortably without compressing breast tissue.

Fullest Bust (Level Tape)
💡 Pro Tip: Stand straight and breathe normally. Look in a mirror to ensure the tape is not slipping down your back.

Your Recommended US Bra Size
34C(34 Band, C Cup)

Based on your snug underbust (32.0") and bust measurement (35.0"), your difference is approximately 3.0 inches, indicating a US band 34 and cup C. Remember that breast tissue density, root breadth, and cup contours (e.g. spacer foam vs unlined lace) will subtly affect the final fit.

How Should a Bra Really Fit?

If your current bra feels uncomfortable, diagnose the issue below to find your corrective adjustment.

Please Note: Bra sizing calculations serve as an educated fitting baseline. Individual breast tissue shape, root width, projection, and asymmetry mean that your perfect fit may vary across different bra cuts (e.g., full coverage minimizer vs plunge lace). We encourage trying both your primary size and sister sizes.
