Finding the Right Fit

Flange size – and your fit – is determined by the width of the flange opening. You can measure your nipple to estimate which size flange is best, then check your flange fit by watching your nipple during pumping. A good fit is when your nipple moves freely in the breast flange tunnel during pumping. You see space around the nipple, and not much of the areola is drawn into the breast flange tunnel with the nipple. A flange is too small when some or all of your nipple rubs against the sides of the breast flange tunnel, and can be uncomfortable. A flange that is too large will allow more of the areola to come into the breast flange tunnel with your nipple and rub against the sides, causing discomfort. Flange fit can change as the breast changes after birth and with pumping. Use a size that feels comfortable and provides the best results.
