HOW DO YOU CALCULATE BRA SIZE?

Two measurements are needed to calculate your bra size. These are your band size and your cup size. Your band size makes up the number while your cup size is represented by the letter.

The only equipment that you need to measure your bra size is a flexible tape measure. You’ll find your bra size by measuring around your rib cage and your bust. Read on to discover how to calculate your bra size correctly.

BAND SIZE

Your band size is the number that you see within your bra size. For example, 30, 36 or 40. This refers to the size of your rib cage.

To measure your band size, wrap your tape measure around your rib cage, directly under your bust. The tape measure should lie exactly where the band of your bra would naturally sit. It should be level and snug. The number in inches is your band size.

This is where many high street stores go wrong as they are renowned for adding several inches to this measurement. This is because back in the 1950s, bras were made from silk and satin and did not stretch. However, fast-forward to the 21st century and our bras now allow for stretch, so we don’t need to add anything onto this measurement.

So, if you measure around your rib cage and find that it is 32 inches, this is your band size. If the number is an odd number, you might need to try the band size below and above to see which fits you best.

CUP SIZE

Your cup size is letters than you see in your bra size, for example B, DD or G. This refers to the size of your breasts in relation to the size of your rib cage.

To measure your cup size, wrap a measuring tape around the fullest part of your bust, level with your nipple, and then round the number in inches to the nearest whole number. You’ll then need to subtract your band measurement from this number.

So, if your bust measurement is 41” and your band measurement is 34”, you’ll do the calculation 41-34 and be left with 6”. You can then use the table below to discover your cup size. In this example, your bra size would be 34E.
