How bra size is calculated
Estimate a US/UK-style band and cup size from underbust and bust measurements in inches. The result is a starting point because sizing systems, brands, fit preferences, and measurement technique differ; sister sizes can feel different across styles. A 34-inch underbust and 37-inch bust suggests roughly 34C under this simple inch-difference rule. The calculation validates each input and keeps its stated units explicit. No. It is a measurement-based estimate; try the brand’s chart and assess band, cup, and wire comfort. This is an estimate for the stated assumptions; confirm measurements and any applicable professional or local standards before relying on it.
