How do I choose the correct breast shield or nipple insert size?

Choosing the right size breast shield and nipple insert for your Philips Avent Hands-free Electric Breast Pump is crucial for a comfortable, pain-free pumping experience that supports efficient milk expression.

Try using one of the interactive tools below to help find the size that works best for you.  

Take your time and measure your nipple carefully. Choosing the correct size will help you express milk comfortably and efficiently.

We highly recommend measuring your nipple multiple times, especially if you've recently given birth, as nipple size changes during pregnancy and throughout your breastfeeding journey.

After measuring and choosing your size, watch the "Checking your fit" video to make sure that the breast shields/inserts you've selected fit and that you're wearing them properly.
