Now we have the luxury of being able to buy bras online and we can avoid the awkward encounter of having a stranger measure us with their freezing cold hands, but that doesn’t mean that we should forego the measurement process altogether.

We have created the ultimate bra size calculator and it is only 3 easy steps!

A Few Tips Before You Get Started with the Bra Size Calculator

  • Wear an unpadded bra or no bra at all when measuring your bra size to ensure that you get the most accurate size.
  • Using a tailor’s measuring tape to measure is best because it is extremely flexible and easy to maneuver (we like this retractable one)
  • Remind yourself that this is just a number and has no correlation to your value as a woman. A certain size breast doesn’t determine your worth. Be honest with yourself in the measuring process so you can find a bra that fits and helps you feel confident.

3 Easy Steps to Correctly Calculating Your Bra Size

Calculating your correct bra size can be done in a few simple steps.

Step 1: Measure Your Band Size.

To measure your band size, use a measuring tape to measure around your ribcage, just beneath your bust. The tape should be snug but not tight. Round to the nearest whole number. If the measurement is an odd number, round to the nearest even whole number.

Step 2: Measure Your Bust Size

To measure your bust size, use a measuring tape to measure around the fullest part of your bust. Make sure the tape is level and not too tight. Round to the nearest whole number.

Step 3: Calculate Your Cup Size

Subtract your band size from your bust size. The difference will determine your cup size. For example, if your band size was 40 inches and your bust size was 46, you would subtract 40 from 46 (46-40=6) and see that the difference is 6 inches. Using the chart below, you can see that a difference of 6 inches is an E(DD) cup size.
