Psst. Take the size quiz instead of reading below, and we'll suggest a size for you.
Step 1: Measure your nipple
Watch this video to see how to measure your nipple for Milkdrop products.
Step 2: Choose your size
Ordering a Milkdrop Pump
Choose the size pump that is the next biggest size from your nipple.
So if you measure:
- Up to 15mm (0.6") choose XS
- 15-20mm (0.6-0.8" choose S
- 20-25mm (0.8-1.0") choose M
- 25mm (1.0-1.2") or over choose L
If you're between sizes, choose the larger size. We will swap out a different cushion size (free of charge) if you find you need it, but it's best to go with a slightly larger flange size, and then reduce it with a cushion.
If you are measuring 25mm+, please contact us at support@milkdroppumps.com so we can double-check your pump setup.
All Milkdrop Pumps come with flange sizes or inserts and cushions. When they arrive try different combinations to see what is most comfortable. You may even find that the flange alone (without the cushion) gets the best out of your body - everyone is different!
Step 3: Check the FAQs
Do I measure before or after pumping?
Measure before pumping. Pumping can swell your nipple, which means you might measure too large!
Which part of the nipple do I measure?
We're looking for the measurement across your nipple at its base, where it meets the areola.
Common mistakes are to measure the areola or the flange size - but we're just looking for your nipple only measurement here!
If you have flat or inverted nipples, try to measure where the nipple skin looks different from the areola - it might be a little lumpier. Try to stimulate your nipple to bring it out slightly to find where to measure.
What if I'm exactly between sizes?
It can get a bit tricky figuring out sizing if you're right on the edge.
If you're ordering just cushions only, then start with the smaller of the two sizes. We offer a free size switch within 30 days of your order.
If you're ordering a pump, then start with the larger of the two sizes. This will mean you receive a slightly larger flange, which you can then use a smaller cushion on. Again, we can send you a size switch within 30 days of your order for the cushion if you need it.
Which pumps are compatible with Milkdrop cushions?
Our cushions are designed specifically for Milkdrop Pumps, because they fit them best.
However, if you purchase the cushions as part of our pump, you can detatch them and use them with other pumps you've previously bought. Check with us at support@milkdroppumps.com to see if your pump is compatible.
Still confused with sizing?
We get it. There's enough to figure out with a new baby. The size quiz takes out the guesswork for you, and even recommends a pump for you if you're not sure.
