How to Choose the Right Flange Size

 


For the most comfortable and effective pumping experience, choose a flange size that is 2-4mm larger than your nipple measurement. Here’s a simple guide:

  • 11mm nipple size → Recommended flange: 13mm or 15mm

  • 15mm nipple size → Recommended flange: 17mm or 19mm

  • 20mm nipple size → Recommended flange: 24mm

  • 23mm nipple size → Recommended flange: 27mm
