How to Measure Correctly
Underbust Measurement
Wrap the measuring tape snugly around your ribcage, directly under your bust. Make sure the tape is parallel to the floor and not too tight.
Bust Measurement
Measure around the fullest part of your bust, keeping the tape parallel to the floor. Don't pull too tight - the tape should be snug but not constricting.
Check Your Posture
Stand up straight with your arms at your sides. Wear a non-padded bra or no bra for the most accurate measurement.

Why Accurate Sizing Matters
Wearing the wrong bra size can lead to discomfort, poor posture, and even health issues over time. An estimated 80% of women wear the wrong bra size without realizing it.
Understanding Band and Cup Sizes
The band size represents the measurement around your ribcage, while the cup size indicates the difference between your bust and underbust measurements. Our calculator automatically computes both for you.
