How to Measure Your Bra Size in USA
- Measure Band Size – Wrap the tape snugly under your bust (in inches). Round to the nearest even number.
- Measure Bust Size – Measure around the fullest part of your bust.
- Find Cup Size – Subtract band size from bust size. Each inch difference equals one cup size (1 inch = A, 2 inches = B, 3 inches = C, etc.).
👉 Example: Band = 34″, Bust = 37″ → Difference = 3 → Bra Size = 34C (USA)
Common Mistakes When Measuring Bra Size
Measuring while wearing padded or push-up bras
Not keeping the tape level around the body
Measuring too loosely or too tightly
