Bra Size Converter & Calculator
Determine your ideal fit using your underbust and bust measurements, and instantly convert between US, UK, EU, and French sizing standards.
Measure snug against the ribcage, directly beneath the bust.
Measure loosely around the fullest part of the chest.
How the Fit is Calculated
Band sizes are derived from the snug underbust measure. In traditional US/UK styling, even underbusts gain +4 inches and odd values gain +5 inches. The Cup depth is calculated directly from the structural discrepancy between the calculated band size and full bust circumference.
Underbust band span is 30.0 in. Bust variance is +4.0 inches, mapping to standard volume indexes.
