Bra Size Calculator

Enter your bra size:

1. Band Size: inches ( >=25 and <=60 )

Measure band size:

1) Remove all articles of clothing from the waist up, including your bra.

2) Wrap the tape around your torso, directly under the root of your breast. Wherever your breast tissue terminates into the torso is where the band should be sitting, even if it seems high.

3) After exhaling, pull the tape tight enough that it feels really snug (because bras are stretchy), but not so tight as to leave a red mark in your skin.

4) Write down this number.

Note: If you have an underbust measurement of 36 inches or more, record the measurement when pulling the tape as tight as possible.

2. Cup Size: inches ( >= 25 and <= 86 )

Measure cup size

1) Lean forward, so that your back is parallel with the floor, so that gravity pulls all your breast tissue forward, even the migrated breast tissue that former ill-fitting bra squished back under your arms and around onto your back.

2) Reach back, and massage your sides, pushing the breast tissue forward with a sweeping motion.

3) Loosely measure around your bust, with the tape passing over the fullest part of your hanging breasts. Don't bend the tape into your cleavage; keep it running straight, touching your breasts in a straight line, perpendicular to the floor. Tighten the tape just enough so that it doesn't easily slide off the skin if nudged, but not tight enough to begin to deform the breast tissue.

4) Write down this number.
