How to Calculate Cup Size
The cup size is calculated based on the difference between bust and underbust circumference.
| Difference between Bust and Underbust (inches) | Cup Size |
|---|---|
| ~ 4 | AA |
| 4 ~ 5 | A |
| 5 ~ 6 | B |
| 6 ~ 7 | C |
| 7 ~ 8 | D |
| 8 ~ 9 | DD/E |
| 9 ~ 10 | DDD/F |
| 10 ~ 11 | G |
| 11 ~ | H |
Final Bra Size Calculation
The final bra size is calculated as follows:
- 1. Determine the band size based on underbust circumference.
- 2. Subtract underbust circumference from bust circumference to get the difference.
- 3. Find the corresponding cup size based on the difference.
- 4. Combine [Band Size] + [Cup Size] to determine the final bra size. (Example: 35C, 40D, etc.)
