How do you measure flanges?
To determine the best flange size for you, you’ll need to measure your nipple. Take a tape measure or ruler and measure the diameter, or width across, of your nipple in millimeters. Do not include measurements for your areola, the larger part around your nipple. Select your flange size based on your measurement.
