- Measure two things: your band (snug under the bust) and your bust (across the fullest point).
- Subtract band from bust. Each inch of difference is one cup letter — 1″ A, 2″ B, 3″ C, 4″ D, 5″ DD.
- Pair your band number with your cup letter. A 32″ band with a 36″ bust is a 32D.
- A cup letter is a difference, not a fixed volume — a 32D and a 36D are different cup sizes.
- Between sizes? Use a sister size — same cup volume, one band over.
- Re-measure every 6–12 months. Brand fit varies; treat the chart as a starting point.
How to Measure Your Bra Size
Two measurements with a soft tape, basic subtraction, a moment to interpret — about five minutes. Measure over a thin, unlined bra (or no bra for the band), and keep the tape parallel to the floor.
Wrap the tape snugly around your ribcage directly under the bust, parallel to the floor, on the exhale. Round to the nearest even inch — bands come in even sizes only (28, 30, 32, 34…).
Wearing an unlined, non-padded bra, wrap the tape around the fullest point of the chest, parallel to the floor, snug but not compressing. For a C cup and above, lean to 90° while measuring.
Bust minus band, in inches. Each inch of difference is one cup letter: 1=A, 2=B, 3=C, 4=D, 5=DD, 6=DDD/F, 7=G. Round to the nearest whole inch.
Pair your band number with your cup letter. A 33″ band (rounds to 32) with a 36″ bust (4″ difference) gives a 32D. A 36″ band with a 39″ bust gives a 36C.
Older guides told you to add four inches to your underbust to find the band. Don't. Modern band elastic is engineered for the direct underbust measurement — adding inches creates a too-loose band, the leading cause of bra mis-fit.

The Master US Bra Size Chart
Find your underbust measurement down the left column, then read across to your bust measurement. Where they meet is your size. The row gives you the band; the cup letter is the bust-to-band difference.
| Underbust (Band) | A (+1″) | B (+2″) | C (+3″) | D (+4″) | DD (+5″) | DDD/F (+6″) | G (+7″) |
|---|---|---|---|---|---|---|---|
| 28″ | 28A · 29″ | 28B · 30″ | 28C · 31″ | 28D · 32″ | 28DD · 33″ | 28DDD · 34″ | 28G · 35″ |

Format: size · bust measurement in inches. Read left to right — a 32″ underbust with a 36″ bust = 32D.
Bra Cup Sizes Explained
The single most misunderstood thing on any bra chart: a cup letter is not a fixed volume. It's the difference between your bust and your band. That's why a 32D and a 36D are not the same cup size — the 36D holds more, because it sits on a bigger band. The cup-size chart below shows what each difference means.
| Bust − Band | US Cup | What it means |
|---|---|---|
| 1″ | A | One inch of projection beyond the ribcage. |
| 2″ | B | The most common starting estimate — often too small once the band is corrected. |
| 3″ | C | The most-shopped cup overall. See C cup size explained. |
| 4″ | D | Last cup that's identical across US, UK, and EU systems. |
| 5″ | DD | Where US and UK sizing begins to diverge. See DD cup size explained. |
| 6″ | DDD / F | US doubles up (DDD); UK and EU continue the alphabet. |
| 7″ | G | Full-bust territory — band fit matters most here. |
Because the cup is a difference and not an absolute, two bras with the same letter on different bands hold different amounts. This is the whole basis of sister sizing — and why the size on your old bra is a poor guide to a new brand.
Sister Size Reference
Sister sizes share the same cup volume on a different band. They solve the most common mis-fit pattern (band wrong, cup right) and roughly triple your shopping range. Going up one band and down one cup letter gives a looser-band sister; going down one band and up one cup gives a tighter-band sister. (For the deep dive, see sister sizes explained.)
| Sister Down (tighter band, larger cup) | Your Size | Sister Up (looser band, smaller cup) |
|---|---|---|
| 30D | 32C | 34B |
| 30DD | 32D | 34C |
| 32C | 34B | 36A |
| 32D | 34C | 36B |
| 32DD | 34D | 36C |
| 32DDD | 34DD | 36D |
| 34C | 36B | 38A |
| 34D | 36C | 38B |
| 34DD | 36D | 38C |
| 36D | 38C | 40B |
| 36DD | 38D | 40C |

"A size chart is a starting point. Brand grading varies, body shapes vary, the same labeled size fits differently across pieces. Use the chart as a hypothesis — and use sister sizing to test it without committing to a wrong number."
