Bra sizes, cup by cup
Bra sizes A, B, C, D, E, F, G, H, I, J, K or L and more: our bras sorted by cup depth, with the available band sizes for each and international equivalents.
This page organizes our models by bra size, specifically by cup depth, from A to L and beyond. Each cup has its own selection, with the actual back sizes available and the shapes that suit it, from cup A to large size bras. The bra size chart below provides the measurement gap corresponding to each letter, allowing for a bra size calculation without trying it on.
The twelve cups and their measurement gaps
- Cup A: 13 cm · Cup B: 15 cm · Cup C: 17 cm · Cup D: 19 cm
- Cup E: 21 cm · Cup F: 23 cm · Cup G: 25 cm · Cup H: 27 cm
- Cup I: 29 cm · Cup J: 31 cm · Cup K: 33 cm · Cup L and above: 35 cm and beyond
International cup equivalents
Up to D, the letters match between France, the UK, and the US. From E onwards, they shift by one letter because Anglo-Saxon systems insert double letters. A French cup E equals a British DD, an F equals an E, a G equals an F, and an H equals an FF. The back size converts separately: a French 90 corresponds to a British 34, and a 95 to a 36. Without this double conversion, a bra size ordered from a foreign catalogue almost always misses the mark.
From cup A to cup L, size by size
Cup A and cup B cater to smaller busts, where the shape is created with padding rather than material. Cup C and cup D form the core of the market and can be found in all collections. From cup E, the selection narrows, and the construction changes significantly: cup F, cup G, and cup H require a reworked pattern, not just an enlarged standard size. Cup I, cup J, and cup K belong to specialist brands, and cup L and above to a handful of references that few retailers agree to stock.
