What is a Breast Pump Flange?
The flange is the breast pump part that comes in contact with your body when placed onto the breast and nipple, forming a vacuum seal with the areola. It's shaped like a funnel. The flange draws your nipple into the tunnel of the pump where milk is extracted.
Whether the shield or flange size of your breast pump is right or not greatly affects your breast comfort and milk output. If you want to ensure the most amount of milk during your pumping and comfort during and after pumping, getting the right measuring size of your nipples is very crucial.

Tips
1. Your left and right nipples may have different sizes, so please measure them both to get the exact size of them.
2. When you start pumping, your nipple size may change. So it's recommended that you choose the size of the flange which is 1-3 mm larger than your nipple's size, or you can measure the exact size when you finish pumping.
Will My Flange Size Change?
Possibly! Your breasts may change between the third trimester and after giving birth. Also, your breasts may change through your breast pumping journey, so it's important to regularly check your flange size.
If you measure your nipples before beginning to pump or before you have your baby, you will want to add 1-3 mm to the measurement you found for your nipple diameter for choosing the correct flange size. This will allow for the amount of swelling that occurs during pumping.
