Measuring Bra Size

We're passionate about helping you find the perfect fit. Use this guide to get it right. And remember—with surgery can come swelling—so you may want to order a band size or two bigger to allow for that. Always be sure to try on your bra before surgery.

Measuring for Band Size
Measure around the rib cage just beneath the breast. Keep the tape snug and straight around the back. Suggested band size based on back measurements:

  • For 29"-32" we suggest a 34 band
  • For 33"-34" we suggest a 36 band
  • For 35"-39" we suggest a 38 band
  • For 39"-41" we suggest a 40 band
  • For 42"-43" we suggest a 42 band
Measuring for Cup Size
To find cups size, measure gently around the body across the high point or fullest point of the bust line while wearing a bra. Subtract the band size from the cup measurement just taken. This difference will help you find the right cup:
  • 3" larger indicates C cup
  • 4" larger indicates D cup
  • 5" larger indicates DD cup
Measuring with Existing Bra
You can also use your everyday bra as a guide. Fasten your bra on the hook you wear it and lay it flat. Measure that length across and compare it with heart&core band measurements to get a true fit:
  • Our 34 band measures 12 inches when flat 
  • Our 36 band measures 13 inches when flat 
  • Our 38 band measures 14 inches when flat 
  • Our 40 band measures 15 inches when flat 
  • Our 42 band measures 16 inches when flat
