Battle of the Bands - Measuring Your Band Size

Measuring bra band size

In a non-padded bra, stand up tall with your arms at your side. Take a deep breath and let it all out — you want this measurement to be as accurate and air-free as possible. Now with the measuring tape parallel to the ground, measure the band that runs around your ribcage, just under your bust. Round this measurement up or down to the nearest whole number.

  • If the measurement is even, add 4”
  • If the measurement is odd, add 5”

Cup a Feel - Measuring Your Cup Size

Step 1: 34” (under-bust measurement) + 4” = 38” Band Size
Step 2: 2 ¾” (measurement from apex to bottom of breast) = 3” (rounded to nearest whole number) = Cup Size C
Step 3: Your bra size is 38C!

Helpful Hints-

You’ve found your size, now make sure it fits with these helpful hints:

  • Bust and band do not go hand in hand. Just because you’re busty does not mean you will need a bigger band size - the cup size is where volume counts.
  • Your cups should be full but should not runneth over. If you’re spilling over the sides, it’s time to re-measure.
