How to measure bra size

Your bra size consists of two parts:

1. The number indicates your band size and represents the measurements directly under your bust.
2. The letter represents your cup size and represents the measurement of your bust at the fullest part of your chest.

1. Measure your band size

To measure your band size you measure yourself around the bottom of the band, directly under your bust. Stand in front of a mirror and keep the measuring tape level and snug. Your band size represents the size of your bra band and is displayed as a number in inches (30-48 inch).

2. Measure your cup size

Measure your bust at the fullest part of your chest (usually at nipple level) if you want to measure your cup size. Keep your measuring tape loosely but level around your bust. Tip: stand in front of a mirror so you can check if your holding the measuring tape the right way.

3. Enter your measurements into the bra size calculator

After measuring your sizes you can enter these measurements into the bra size calculator to discover the right bra size for you. Your bra size is determined based on the measurements you enter into the bra size calculator. You should bare in mind that every woman is unique and that the suggested bra size is the perfect bra size for you on paper. Therefore it is very important to always check the bra fit as well. This way you can check which bra suits your body and feels comfortable. It is also good to know your sister sizes. Is your bra size a 75C? Then your bigger sister size is a 70D (one band size down, one cup size up). Your smaller sister size would be a 80 B (one band size up, one cup size down). Again the bra fit plays an important role. Make sure that it feels comfortable and that the bra suits your body. A new bra can feel tight when wearing it for the first time. Don’t stress that your new bra size isn’t the right size for you! Your bra band will stretch over time. Just make sure that you can fit two fingers between your bra band and your body.
