Elvie Pump FAQs

What Breast Shield sizes are available and how will I know if they’ll fit?

Elvie Pump comes with a 24mm and 28mm Breast Shield (often called a flange), a pack of two 21mm Breast Shields is also available to purchase.

Our Breast Shields are sized based on the width of the base of your nipple. You can measure the width of the base of your nipple with a ruler. The Breast Shield sizes are as follows:

  • Base of nipple width between approximately 16mm and 18mm = 21mm breast shield
  • Base of nipple width between approximately 18mm and 21mm = 24mm breast shield
  • Base of nipple width between approximately 21mm and 25mm = 28mm breast shield

The size of your nipple may change over the course of your breastfeeding journey, so please keep the other Breast Shields that are included in the box in case you need them at a later date.
