You’ll need to determine your rib band and cup size measurements in inches.
Step 1: Band Measurement
Measure your chest above your breasts - make sure the tape is around your back and under your armpits. Check in the mirror to ensure the measuring tape is parallel to the floor along your back. The tape should be snug around your body without any fingers underneath the tape. If you are in between band sizes, round up or down to the nearest even number. This will be your rib band size (34, 36 etc.).

Step 2: Bust Measurement
Measure around the fullest part of your breasts, over your nipple area. This is a looser measurement than the rib band measurement. While holding both ends of the tape with one hand at the side of your breast, use your free hand to press the measuring tape in between your breasts to your chest. Subtract your band size from your bust measurement. This is your cup size.

Step 3: Calculate Your Nursing Bra Size
Subtract your Over Bust Band Measurement
froim your Full Bust Measurement to deterimine your Cup Size. (See chart below.)
Use the measurement over your bust to determine your Band Size.
