Measuring for Band Size
For the most accurate measurement we suggest you remove your top and leave your bra on. Wear a bra that is free of padding to ensure an accurate measurement.
To measure for your band size, place the measuring tape around the ribcage, directly under the bust. Make sure the tape is straight and flat across the back and parallel to the floor. Pull the tape snug. Round the measurement to the nearest even number. This number will be your band size and is the first step in determining what bra size you are.
Measuring for Cup Size
To determine your cup size, measure at the fullest part of the bust with the tape parallel to the floor. If someone is measuring you, make sure to keep your arms at your side. Do not pull the tape snug, but rather pull the tape just gently enough to keep it in place. Round the number up or down to the nearest full inch. Write this number down on a piece of paper with the words “cup measurement” next to it.
Calculating Your Size
Each inch difference between your cup and band measurement represent a cup size:
1 inch difference: A Cup
2 inch difference: B Cup
3 inch difference: C Cup
4 inch difference: D Cup
5 inch difference: E Cup
