Up to 80% of women wear the wrong bra size. Measuring at home takes less than 5 minutes — all you need is a soft tape measure.
Wrap the tape firmly around your ribcage, directly under your bust. Snug but not tight.
| Measurement (cm) | AU Band |
|---|---|
| 63–67cm | 10 |
| 68–72cm | 12 |
| 73–77cm | 14 |
| 78–82cm | 16 |
| 83–87cm | 18 |
| 88–92cm | 20 |
| 93–97cm | 22 |
| 98–102cm | 24 |
| 103–107cm | 26 |
Measure around the fullest part of your bust, tape parallel to the floor. Don’t pull tightly.
Subtract band measurement from bust measurement. The difference is your cup size.
| Difference | Cup | Difference | Cup |
|---|---|---|---|
| <1cm | AA | 15–16cm | FF |
| 1–2cm | A | 17–18cm | G |
| 3–4cm | B | 19–20cm | GG |
| 5–6cm | C | 21–22cm | H |
| 7–8cm | D | 23–24cm | HH |
| 9–10cm | DD | 25–26cm | J |
| 11–12cm | E | 27–28cm | JJ |
| 13–14cm | F | 29cm+ | K |
Example: Underbust 78cm = band 16. Bust 91cm − 78cm = 13cm = F cup. Your size is 16F.
