What is my flange size ?

1. What do we measure?

The nipple only, not the areola.

2. How do we measure it?

Using a ruler or tape measure, measure the nipple diameter at its base (top to bottom) in millimeters (mm).

Diagram: measuring nipple diameter at the base

3. How to choose the size?

Based on your measurement, select the corresponding flange size.

Measurement Flange size
Up to 11 mm 15
11 mm to 14 mm 18
14 mm to 17 mm 21
17 mm to 20 mm 24
20 mm to 25 mm 27

Example: if your nipple measures 16 mm in diameter, the recommended flange is size 21.

If you need a smaller size, you can order these Amazon adapters and combine them with our size 24 flanges.

💡 As a general rule, go with the larger size if you're between two sizes.

Simple rule: a comfortable pumping session = an effective one. Milk should flow easily, without pain or friction.

4. How do I know if I have the right flange size?

As soon as you receive the product, we recommend checking the flange size before starting to pump.

Correct flange size

✅ Right size

The nipple is centered and moves freely; it doesn't touch the sides of the flange.

→ This is the right size.

Flange too small

❌ Too small

The nipple rubs against the side of the flange.

→ Try a larger flange.

Flange too big

❌ Too big

The nipple and excess areola tissue get pulled into the tunnel.

→ Try a smaller flange.

Other warning signs of an incorrect size:

  • Visible redness;
  • Nipple or areola turning white;
  • Feeling that milk wasn't fully expressed.

If you notice any of these signs, try a different size. You can also reach out for guidance at support@perifit.co.

5. Did you know?

  • Each breast may need a different size. In that case, two options:
    1. Buy two single Perifit Pumps in different sizes using code MIXMATCHDOUBLE.
    2. Buy a Perifit Pump Double and add an extra flange separately.
  • Size depends on breast tissue and skin elasticity.
  • Your size may change over the course of breastfeeding.
  • The pump should be held securely in your bra, without compressing the breast, so milk can flow freely.
  • For optimal support, use it with the Perifit nursing bra.

6. Practical info

  • Most common sizes: 21 mm and 24 mm.
  • All sizes are available individually on our site.

7. Choosing your nursing bra size

Perfect

The size of the pouch is perfect for Perifit. Too bad it only comes in black 😊

Great pouch, well suited for my Perifit, its instructions, and a pack of intimate wipes to clean it after each use.

Love perifit pump

I love that bottles can be easily bought extra. Only remark; the volume mentioned on the bottles are not correct. When they are put in a bottle to drink, it can differ easily up to 20mL

I had a little problem with the bottle but the after-sales service was magical.
This breastpump is so practical, and perfectly suited to my speed life.
Only downside sometimes the app bugs but fortunately we do not have to go through the app to use it .... I recommend 100%

I bought it 3 months ago for the return at work. I am a nurse, my baby is 10 months old and it allows me to pump during the commute, at work, during my break ...
I am very happy with it. Only issue I think I boiled it for too long. The bottle have shrunk, but the customer service sent me 2 new bottles for free. It takes time to clean it properly. But it is a freedom that I do not regret.

The bottle is sensitive to high temperatures! If sterilization is too hot it deforms and becomes unusable. But the customer service was super proactive in sending me a replacement.

I pump my milk 8 times a day and thanks to perifit I save a considerable time because I get as much or more milk than before in less time (20 minutes vs 40) and I can do my other tasks at the same time.
It's not noisy, I pumped during lunch in a restaurant and nobody could hear.
And I am free to move with a small bag, pumping any time while driving, walking, etc.
Finally, my flanges were too small, the after-sales service was very responsive and sent me a new larger pair without cost. I recommend 100%.
