How to Measure Your Bra Size

Find your perfect bra fit - measurement guide illustration

How to Measure Your Bra Size

Step 1: Measure Your Band Size

Put on a non-padded bra and stand in front of a mirror. Wrap a measuring tape snugly around your ribcage, just below your bust. Keep the tape level and flat against your body. Take the reading after a relaxed exhale. If the number is odd, round up to the next even number (e.g., 33" → 34").

Step 2: Measure Your Bust Size

Wrap the measuring tape around the fullest part of your bust. Keep the tape level - snug but not tight. Breathe naturally and take the reading in a relaxed state. Do not pull the tape taut or hold your breath.

Step 3: Calculate Your Cup Size

Cup Size = Bust Measurement − Band Measurement

	27.5-29.5″	29.5-31.5″	31.5-33.5″
Band size	32	34	36

33.5-35.5″	35.5-37.5″	37.5-39.5″	39.5-41.5″
38	40	42	44

	27.5-29.5″	29.5-31.5″	31.5-33.5″	33.5-35.5″	35.5-37.5″	37.5-39.5″	39.5-41.5″
Band size	32	34	36	38	40	42	44

DIFFERENCE (BUST SIZE − BAND SIZE)
