Reading the chart correctly

Bands convert cleanly (US 34 = EU 75 = FR 90 = AU 12); cups are where systems diverge, and the divergence starts after D. The chart shows each system's own ladder rather than forcing letters to match, because forcing them is how a UK FF gets mislabeled as an American G. When any brand publishes a centimeter chart, that chart wins over these conversions; this reference is for when all you have is a foreign label.

Frequently asked questions

How do I use a bra size chart?
Find your band row from your snug underbust measurement, then your cup letter from the bust-minus-band difference (one inch per letter). Read across for the same size in every system, and diagonally for sister sizes.
What is my UK size if I wear a US DDD?
A UK E at the same band. US DDD, UK E and EU F all describe roughly a six-inch bust-band difference with different letters.
Why do Japanese sizes look different on this chart?
Japan prints the cup before the band (C75) and its letters run about one letter fuller than European for the same measurements, both reflected in the JP and KR columns.
