3 Easy Steps to Correctly Calculating Your Bra Size

Calculating your correct bra size can be done in a few simple steps. Here is a general guide:

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.
