Choosing the correct breast pump flange size is crucial for a comfortable and effective pumping experience.

Using the wrong size can lead to pain, discomfort, and reduced milk production.   

How to Measure Your Nipple

  1. Stimulate your nipple: Gently stimulate your nipple to encourage it to its natural size. 
  2. Measure the diameter: Use a soft measuring tape to measure the widest part of your nipple.
  3. Add 2-3mm: Most experts recommend adding 2-3mm to your nipple measurement to determine the ideal flange size. 

Note: Your nipple size may change over time, so it's important to remeasure periodically.

Common Flange Sizes

  • 15mm to 40mm: This is the typical range of breast pump flange sizes.
  • 24mm: Many pumps come with a standard 24mm flange, but this might not be the right size for everyone.   

Signs of a Poor Flange Fit

  • Pain or discomfort during pumping
  • Nipple damage
  • Inefficient milk removal   
  • Breast tissue being pulled into the flange

Additional Tips

  • Consider nipple shape: Some nipples are longer or shorter than average, which can affect flange fit.
  • Experiment with different sizes: Many pump kits come with multiple flange sizes. Try different ones to find the best fit. 
  • Consult a lactation consultant: If you're having trouble finding the right flange size, a lactation consultant can help.

Remember: The goal is to find a flange that creates a gentle seal around your nipple without causing any discomfort.
