Confirm the chart first. This compares labels using Triumph’s published EU, US and GB columns. It does not claim every Chinese, American or British brand uses this sequence.
Have a US size instead? If your tag reads 34B or 36C and you need the Chinese label, use the US bra size to Chinese converter.
Chinese bra band size to US / UK chart
A label such as 75B has two components: the nominal band and cup. This tool treats the centimetre-number band as EU-style only when the seller follows that system. The band number is a size label; do not convert 75 cm directly into inches and call it a US band.
| EU-style band | US / UK band |
|---|---|
| 65 | 30 |
| 70 | 32 |
| 75 | 34 |
| 80 | 36 |
| 85 | 38 |
| 90 | 40 |
| 95 | 42 |
| 100 | 44 |
| 105 | 46 |
| 110 | 48 |
Cup letters need their own conversion
Use the same row across this named reference. After D, matching the same letter across systems can give the wrong comparison. UK brands using FF or GG require their own chart; those letters are not present in this Triumph GB sequence and the tool does not guess them.
| EU-style cup | US cup | UK (GB) cup |
|---|---|---|
| AA | AA | AA |
| A | A | A |
| B | B | B |
| C | C | C |
| D | D | D |
| E | DD | DD |
| F | DDD | E |
| G | G | F |
| H | H | G |
| I | I | H |
| J | J | J |
| K | K | K |
| L | L | L |
Worked examples: B65, 75B and 100E
B65 is normalised to 65B, which compares with US 30B and UK 30B in this reference. An EU-style 75B compares with 34B. An EU-style 100E compares with US 44DD and UK 44DD. For reverse lookup, select US and enter 34DDD to compare with EU-style 75F and Triumph UK 34E.
Can this calculate my size from body measurements?
Quick answers: common Chinese bra sizes in US sizes
Read the Chinese label, then find its US band and cup. Band 75 is US 34, 80 is 36, 85 is 38 and 90 is 40; cup letters A to D stay the same, while E becomes DD.
| Chinese label | US size | UK size |
|---|---|---|
| 75A | 34A | 34A |
| 75B | 34B | 34B |
| 75C | 34C | 34C |
| 80A | 36A | 36A |
| 80B | 36B | 36B |
| 80C | 36C | 36C |
| 85B | 38B | 38B |
| 85C | 38C | 38C |
| 85D | 38D | 38D |
| 90C | 40C | 40C |
For other sizes, enter the label in the converter above, or open a single-size page: 75A to US, 80B to US, 85C to US.
This is a label converter. It does not choose a new bra from bust measurements, infer a cup from clothing sizes, or suggest a sister size without a fitting context. For a purchase, use the product’s underbust and bust chart and fitting instructions; style, stretch and brand can change the fit.
Reference, range and limitations
Source: Triumph international size charts, bra sizes and cup indicator, checked 2026-10-15. Band labels 65–110 and the listed AA–L EU cup sequence are supported as label comparisons. This does not mean every combination is sold or will fit. If a Chinese seller uses another cup progression, use that chart instead.

Reference answer
Using Triumph’s international sequence, an EU-style 75B label compares with US 34B / GB 34B. An EU-style 75F compares with US 34DDD / GB 34E.
Scope: Band and cup must both be converted. This is label comparison, not a fitting prediction.
