Elvie Sizing Guide
The Breast Shield (or flange) is one of the most important parts of your pump. If it doesn’t fit you, using your pump could be like wearing the wrong bra. Awkward, frustrating, and pretty damn uncomfortable. Luckily we're on hand with this helpful guide to help you find the right combination of products for you.
Which size is right for me?
We've created a handy tool to help you find your nipple measurement and choose the right product combination for you.
Already know your nipple measurement?
Use the below table to find your recommended fit:
11 mm - 12 mm
15 mm Nipple Cushion placed in 24mm Breast Shield
13 mm - 15 mm
17 mm Nipple Cushion placed in 24mm Breast Shield
15 mm - 17 mm
19 mm Nipple Cushion placed in 24mm Breast Shield
17 mm - 19 mm
21mm Breast Shield
20 mm - 22 mm
24mm Breast Shield
23 mm - 26 mm
28mm Breast Shield
Your pump uses a breast shield to connect your nipple with the pump. Elvie makes these in 21 mm, 24 mm and 28 mm. You can purchase additional Breast Shields with our accessories.
If you have smaller sized nipples you might also need Elvie Nipple Cushions. These fit inside 24mm Elvie Breast Shields (which are included with all Elvie breast pumps).
Understanding breast pump sizing
Why is sizing so important?
No two ways about it. The Breast Shield is kind of a big deal. It connects your pump to your body. If it doesn't fit, you might experience decreased milk volumes and pain or discomfort.
Not ideal, right? Well, the good news is that different Breast Shield sizes are available to help you find your perfect fit.
What if the Elvie Breast Shields are too big?
Elvie also makes Nipple Cushions, which are soft, silicone accessories that you can place inside a 24mm Breast Shield to help size down your shield and provide extra comfort. Elvie Nipple Cushions are available in size 15mm, 17mm or 19mm.
What am I sizing?
Good question. The answer is your nipple. More specifically, the width of the base of your nipple. The base of your nipple is where it meets the areola.
It’s important to size both of your nipples. No two nipples are the same, so you might find you need different sizes for left and right.
How do I find the right size?
Already own an Elvie Breast Pump and Shields? You can use the fit lines on the Breast Shield itself. To see if a Breast Shield fits, start by putting it on your nipple. If it fits you, the fit lines should line up with the outside of your nipple.
Yet to buy an Elvie Breast Pump? We'd recommend using our sizing tool before you buy.
Do my nipples really change size?
Yup, they certainly do. Your nipples could get bigger or smaller before and after giving birth.
This is why It’s really important to check your Breast Shield sizing during your pumping journey. We’d recommend doing this every couple of weeks.
Where do I start?
The best place to begin is by taking some time to use our Elvie Nipple Sizing tool. We'll take you step-by-step through measuring your nipple and choosing the right product combination for you.
