Bra Size Calculator

Calculate your bra size by entering your measurements below. For the most accurate results, measure directly against your skin using a soft measuring tape.

How to Measure

Band Size:

Measure around your torso directly under your bust, where a bra band would sit. The measuring tape should be snug but not tight. Round to the nearest whole number.

Bust Size:

Measure around the fullest part of your bust. Make sure the measuring tape is parallel to the ground and not too tight.

Tips for the Perfect Fit

  • The band should be snug but comfortable, and parallel to the floor
  • The center of the bra (between the cups) should lie flat against your sternum
  • The cups should fully contain your breast tissue without spillage or gaps
  • The straps should stay in place without digging into your shoulders
  • If you're between sizes, try both to see which feels more comfortable
