Choosing the right breast pump can be a game-changer for breastfeeding moms, especially for those with large breasts who need a comfortable, efficient, and well-fitting pump. In 2025, the market offers a variety of breast pumps designed to cater to different needs, from wearable and hands-free options to hospital-grade electric pumps. This guide compiles the best breast pumps for large breasts, focusing on comfort, effectiveness, and compatibility with larger flange sizes. We’ve gathered insights from real moms, lactation consultants, and rigorous testing to highlight top choices, their pros and cons, testing scenarios, and a buying guide to help you make an informed decision.
Why Choosing the Right Breast Pump Matters for Large Breasts
Finding a breast pump that fits well is crucial for moms with large breasts. The flange, or breast shield, is the part of the pump that fits over the nipple and areola, and its size directly impacts comfort and milk output. A flange that’s too small can cause pain, reduce milk flow, or even lead to clogged ducts, while one that’s too large may not provide adequate suction. For moms with large breasts, standard 24mm flanges often don’t suffice, and pumps offering larger flange sizes (27mm, 30mm, or more) or customizable options are essential. Comfort, portability, and suction strength also play significant roles in ensuring a positive pumping experience.
Top Breast Pumps for Large Breasts in 2025
Below, we’ve curated a list of the best breast pumps for large breasts based on mom reviews, expert testing, and compatibility with larger flange sizes. Each pump has been evaluated for comfort, efficiency, and suitability for daily use.
Spectra S1 Plus
The Spectra S1 Plus is a popular choice among breastfeeding moms for a good reason. Whether it is top marks in our testing or user reviews online, everyone can agree that this is a comfortable and efficient pump for most moms. One of our lactating moms said, “I loved this pump, it was comfortable and pumped so quickly I was done in half the time as other pumps.” With a rechargeable battery, you can pump wherever and whenever necessary. This pump has a strong, adjustable suction featuring 12 suction levels and different speeds. In our tests, it pumped 0.55 ounces of milk per minute. It is also pretty quiet, with a measured decibel reading of 44.5 dB in our tests.
- Pros: Expresses milk quickly and comfortably. Closed system — safe for multi-person use. Lightweight at just over 3 pounds.
- Cons: The tubes fall off easily during pumping (which means they need to be replaced). The pump vibrates during usage.

Medela Pump In Style Advanced
The Medela Pump In Style Advanced model has many features that make it a good investment. Plus, for women with large chests and bigger than average nipples, the nice thing is that you can separately buy extra-large breast shields to make this pump work. Nipple size also varies during breastfeeding, so you will want to have easy options to grab. The Pump In Style Advanced kit already comes with two sizes of breast shields – the 24mm and 27mm. Before automatically ordering the extra-large shields, you should give the included shields a test drive. The nipple shouldn’t hit the side of the flange, you also shouldn’t be sore from pumping.
- Pros: Mimics the natural sucking rhythm of babies — more comfortable. Double pump system for more milk in less time. Easy to use and clean.
- Cons: The charge only lasts two hours, so it might need to be recharged a few times a day. The suction power could be better.

Elvie Stride
For mamas wanting a hands-free pumping solution, look no further than the Elvie Stride Double Electric Breast Pump. With its portable, lightweight design and silent operation, it allows users to express milk discreetly and comfortably making it ideal for mums going back to work. Our mum tester, Samantha, found it to be a game changer when she returned to work. “In the morning, when I needed to express myself, I would be in the house working and would find it extremely convenient that I could still use both hands to type. I found that gave me back so much freedom, and most of the time, I would catch myself forgetting that I was expressing milk,” She said.
- Pros: Lightweight, effective, easy to use, and made from higher-quality components. Offers the strongest suction at 300 mm Hg among wearable pumps.
- Cons: Naturally, because of its wearable design, it doesn’t offer the cup capacity of other hospital-grade breast pumps, meaning it requires more frequent emptying.
Pumpables SuperGenie
The Liquid Shield Kit (sold separately) provides a perfect flange fit, with soft silicone that “conforms to the body slightly,” says Anderson. “I love the Pumpables liquid flanges. They’re super comfortable and often the answer for someone who needs to pump eight times a day and is tired of pumping on hard plastic.” This added comfort is a game-changer for moms who pump frequently.
- Pros: Super comfortable Liquid Shield Kit. Powerful and lightweight. Long battery life of three to four hours.
- Cons: The shield kit has many pieces that aren’t dishwasher-friendly. Slightly heftier than some portable pumps.

Momcozy S9 Pro
The Momcozy S9 Pro is the only one of our picks that has flanges made from food-grade silicone, which we found was more comfortable against the breast than plastic. This pump is also easy to assemble and clean. But it has an awkward shape, so it was the most obtrusive of our picks, and the battery life wasn’t as long.
- Pros: Affordable with powerful suction. Comfortable silicone flanges. Easy to assemble and clean.
- Cons: Awkward shape makes it less discreet. Shorter battery life compared to other wearable pumps.

Testing Scenarios and Performance
To evaluate these breast pumps, testers conducted real-world and lab-based scenarios to assess efficiency, comfort, and usability. Below are key testing scenarios and findings:
Efficiency Testing
We put each pump through rigorous testing to see how it performs, how it works, and how it feels for users. We evaluated factors like efficiency, comfort, ease of use, portability, hygiene, and more. For example, the Spectra S1 Plus pumped 0.55 ounces of milk per minute in lab tests, making it one of the most efficient. The Elvie Stride, tested by a working mom, allowed her to pump discreetly while typing, yielding consistent milk output comparable to standard electric pumps.
Comfort Testing
Comfort was assessed by moms using pumps for multiple sessions daily. The Momcozy S9 Pro’s silicone flanges were rated highly for comfort, with testers noting no discomfort even on higher settings. The Pumpables SuperGenie’s Liquid Shield Kit was praised for its soft silicone, which conformed to the breast, reducing fatigue during frequent pumping.
Portability and Real-Life Use
Testers used pumps in various settings: at home, in the car, at work, and during travel. The Elvie Stride scored high for portability, with one tester noting she could pump while making tea or working. The Spectra S1 Plus, while bulkier, was favored for its long battery life, allowing untethered use at home.
Noise Level Testing
Noise was measured using a decibel meter app placed 3 feet away. The Spectra S1 Plus registered at 44.5 dB, described as “purring like a kitten.” The Elvie Stride was nearly silent, ideal for office or nighttime use, while the Momcozy S9 Pro was noted as slightly louder but still discreet under clothing.
Buying Guide for Breast Pumps
Choosing a breast pump for large breasts involves several considerations to ensure comfort and efficiency. Here’s a step-by-step guide based on expert advice and mom feedback:
- Determine Your Pumping Needs: The type of breast pump—or breast pumps—you’ll need depends on when, where, and how often you’ll be using it. “The first thing to think about is how the parent will use the pump. So a regular separation, for example, versus going back to work or school, where you’re going to be separated from your baby every day for several hours,” says Jacque Ordner, an International Board Certified Lactation Consultant (IBCLC).
- Check Flange Size Compatibility: While breast pumps themselves do not come in different sizes, crucial breast pump parts called flanges, or breast shields, do come in different sizes, and finding the right fit for you is critical for optimizing milk output and comfort. “There are measuring tools; however, we recommend starting with the flange that comes with your pump and then buying one size smaller as well,” says Harvey. Most pumps come with 24-millimeter flanges, and Medela did a study which suggests that about 95 percent of women are 21s to 24s.
- Consider Comfort and Fit: Comfort: Does the pump fit your body well? With any pump, it’s crucial to make sure you can get compatible flanges that fit the size of your nipples. Loudness of the pump: Some pumps have motors that are louder than others. It can be hard to know how loud a pump is until you’ve tried it, so be sure to read reviews to determine whether a pump you’re interested in purchasing is louder or on the quiet side.
- Evaluate Power Source and Portability: If you’re planning to exclusively pump right out the gate, you might want a device that’s strong enough to get your supply flowing when you’re still in the hospital or just recently home. In this situation, you may want to use a multi-user pump, sometimes called a “hospital-grade pump.”
- Look for Additional Accessories: In addition to your breast pump, you may look for other accessories that can help streamline the pumping process, such as breast milk storage bags, nursing pads, nipple creams, and nursing bras. Don’t forget to consider cost effective ways to test out a potential pump before buying it. Some hospitals offer pump rentals.
Frequently Asked Questions (FAQ)
What flange size should I use for large breasts?
Flange size depends on nipple diameter, not breast size, but moms with large breasts often need larger flanges (27mm, 30mm, or more) for comfort. Use a nipple ruler or consult a lactation consultant to measure your nipple size. Start with the flange included with your pump and test larger or smaller sizes as needed.
Are wearable breast pumps suitable for large breasts?
Yes, wearable pumps like the Elvie Stride and Momcozy S9 Pro are suitable, provided they offer compatible flange sizes. These pumps are discreet and hands-free, ideal for multitasking, but may have lower milk capacity, requiring more frequent emptying.
How often should I pump?
The American Academy of Pediatrics recommends breastfeeding exclusively for six months. According to the AAP, breastfeeding gives your baby antibodies just as they received in utero, which improves their immune system. When your baby is gaining weight and keeping a moderate weight, experts recommend waiting 6 weeks to use a breast pump to first establish a nursing routine.
Can I rent a hospital-grade pump?
Yes, hospital-grade pumps like the Medela Symphony are available for rent from hospitals or medical supply companies. These are ideal for exclusive pumpers or moms with supply challenges but may not be as portable as personal-use pumps.
