How to Measure Your Bra Size in 3 Simple Steps
You only need a soft measuring tape and our easy-to-follow guide.
Step 1: Measure Your Band Size (Underbust)
Wrap the tape snugly around your ribcage, just below your bust.
Keep it parallel to the ground and take the measurement in inches.
If the number is even, that’s your band size. If odd, round up.
? Example: If you measure 31 inches, your band size is 32.
Step 2: Measure Your Bust Size (Overbust)
Measure around the fullest part of your bust (without squeezing too tight).
Round to the nearest whole number.
Step 3: Calculate Your Cup Size
Subtract your band size from your bust size and use the difference to find your cup:
| Difference (inches) | Cup Size |
|---|---|
| 0-1 | AA |
| 1 | A |
| 2 | B |
| 3 | C |
| 4 | D |
| 5 | DD/E |
| 6 | DDD/F |
| 7 | G |
| 8 | H |
? Example:
Band size = 34 inches
Bust size = 38 inches
Difference = 4 inches → D cup
Your bra size = 34D
