How do I know what size Flanges will fit me?

Our ELEBEBE breast pump comes in three flange size options 21mm, 24mm and 27mm. You can also purchase an extra convertor offering the ability to size even smaller to 17mm or 19mm if needed.

To determine your "SIZE", you have to measure your nipple size as follows:

Stimulate your nipple so that it stands up and use a ruler to measure the width (diameter) of the nipple base (don't include the areola).

If you are currently pregnant consider sizing up a few millimeters as your nipple size can get slightly larger following childbirth.

Finding the best fit breast shield is important for both your comfort and effectiveness of the breast pump. Once you are pumping, if you have any discomfort or concerns about your size we recommend talking to a Lactation Consultant.
