How to Measure Bra Size

1. Measure Underbust (Band Size)

Stand straight and wrap a measuring tape snugly around your ribcage, just under your bust where the bra band sits. Keep the tape level all around your body and do not pull too tight.

Write down this measurement in inches. This number is your band size. Common band sizes include 32, 34, 36, and 38.

2. Measure Bust Size

Wrap the measuring tape around the fullest part of your bust. Make sure the tape is straight across your back and not too tight.

Note this measurement in inches.

3. Calculate Cup Size

Subtract the underbust measurement from the bust measurement. The difference determines your cup size.

Difference (inches) Cup Size
1 A
2 B
3 C
4 D
5 DD

Example: If your underbust is 32 inches and your bust is 36 inches, the difference is 4 inches. Your bra size would be 32D.
