E at 5 in, system by system
A cup letter stands for a difference between bust and band. The same letter sits at a different difference in some systems.
| System | Difference (in) | Difference (cm) | Written as |
|---|---|---|---|
| US | 5 | 12.7 | DD/E |
| UK | 6 | 15.2 | E |
| EU | 5 | 12.7 | E |
| FR/BE | 5 | 12.7 | E |
| AU/NZ | 6 | 15.2 | E |
| JP | 4 | 10.2 | E |
| EU method (cm) | Measured in cm | 20 to 22 cm | E |
Where sources disagree about E
- US letters: most charts print DD/E, DDD/F and DDDD/G, and some US brands use other sequences between D and H.
- UK double letters: FF, GG and HH appear in many UK charts, and one UK retailer leaves out some of them.
- JP letters vary by brand, and the JP column follows one label chart.
Three inch values sit behind E: 5 in, 6 in and 4 in. The US figure for 5 in is 12.7 cm.
At 5 in, US tags print DD/E, UK and AU/NZ tags print DD, EU and FR/BE tags print E, and JP prints F. A single cup may carry another letter depending on where its tag comes from.
F follows E in all six systems. DD precedes it in UK and AU/NZ, and D precedes it in EU, FR/BE and JP. F stands for 6 in, one more than E on a US tag.
The EU method sets E at 20 cm to under 22 cm. Your bust runs 36.5 to 37.5 in on band 32 (92.7 to 95.3 cm), then 38.5 to 39.5 in, 40.5 to 41.5 in and 42.5 to 43.5 in as the band grows through 34, 36 and 38.
Beside 34E stand sister sizes 32F and 36D; beside 36E stand 34F and 38D. A US tag marks DD and E as the same 5 in, so neither letter says more than the other.
