If you’re anything like me, at some point in your life you’ve had the experience of something that was just “not a good fit” – the wrong partner, the wrong job, the wrong size outfit or bra. What started out as “those adorable pumps that match my Holiday dress PERFECTLY” are now just a painful memory in the Goodwill box in the garage. Ladies, those shoes might still be in your closet if you had just gone with a slightly wider toe and a somewhat smaller heel!! Just like so many other things in life a good fit can mean the difference between a great experience and a painful one.
Incorrectly sized breast pump flanges (or breast shields) can lead to soreness, blocked milk ducts and ultimately lack of milk production. Learning how to figure out what size flange is right for you can help you avoid problems before they begin.
The standard flange is going to be 24mm – so when measuring, you can start with that. Center your nipple and gently hold the breast shield in place. While doing this you are going to want to put your pump in the “expression mode” and be looking for several things when you turn the pump on.
These can all be signs of the wrong size flange! When your breast pump flange size is correct, your nipple is centered and moves freely in and out of the tunnel. It should mimic baby more like a gentle suck/tug, NOT be painful or cut off blood flow in any way. Make sure to perform this on both sides in case you need two different flanges. Having a good fit will allow for a good start to a comfortable and productive pumping experience!
Keep in mind that breast pump flange fit can change between the time you give birth and when you actually begin using a breast pump. What fits when you began breast pumping may change, so it is important to check your breast pump flange fit from time to time.
When determining the right breast pump flange size, remember the word ‘COMFY’. This term was specifically designed to help moms just like you remember five guidelines about breast pump flange sizing.
Your nipple should move freely in the breast pump flange tunnel. You should not experience any rubbing.
(If you do, this indicates your breast pump flange is too small).
If your nipple is able to move freely in the breast pump flange tunnel you will notice there will be
a gentle pulling movement in the areola each time your breast pump cycles. If there is no movement
in the areola, your breast pump flange is more than likely too small. On the contrary, if there
is a lot of movement or a large amount of your areola is pulled into the tunnel, your breast shield
is probably too big.
You should see gentle breast movement with each cycle of the pump just as you do with your nipple. Gentle
breast movement indicates your breast is getting proper stimulation while pumping.
Using a breast pump should not be uncomfortable for you nor should it cause nipple pain or tenderness.
If you experience pain or discomfort, more than likely you have an ill-fitting breast pump flange.
Your breasts should feel soft after each use of your breast pump.
We hope this breast pump flange size chart has helped you determine if your breast pump flanges fit correctly.

I am 47 years old - I am originally from L.I. New York but moved to NC when I was 23 years old and never
left! My breastfeeding background includes breastfeeding all three children for a period of 7 years total
from 1991-1998. I was also very involved in my local La Leche League during that time. I cannot say enough
good things about breastfeeding and how important and rewarding it is for both mom and baby!
