Breast pumping is an essential part of many mothers’ journeys, and ensuring comfort and efficiency during this process is paramount. A key component often overlooked is the breast pump flange, also known as a breast shield. Using the correct flange size is not just about comfort; it’s crucial for effective milk expression and preventing discomfort. If you’re using a Medela breast pump, understanding the Medela Flange Size Guide is the first step towards a more comfortable and productive pumping experience.
What is a Breast Pump Flange?
A breast pump flange is the funnel-shaped plastic piece that comes into direct contact with your breast when you pump. It creates a seal around your nipple, allowing the pump to effectively draw milk. Flanges are designed to fit over your nipple and areola, creating a vacuum that mimics a baby’s natural suckling. They come in various sizes, typically ranging from 15mm to 36mm, although the size you need isn’t determined by your overall breast size, but rather by the size of your nipple. Most breast pumps, including Medela pumps, usually include a standard 24mm flange. However, this size is not a one-size-fits-all solution.
Why Medela Flange Size Matters for Comfortable Pumping
Using the right Medela flange size is crucial for several reasons, all contributing to a more positive and effective pumping experience. Medela, a leading brand in breast pumps, designs its flanges with the mother’s comfort and milk output in mind. An incorrectly sized flange, whether too small or too large, can lead to a range of problems:
- Pain and Discomfort: A flange that is too small can cause nipple rubbing and pain, making pumping an unpleasant experience. Conversely, a flange that is too large can pull in too much areola tissue, also leading to discomfort.
- Reduced Milk Output: If the flange doesn’t fit correctly, it can hinder milk flow. A flange that is too small might restrict the nipple, while a flange that is too large might not create a proper vacuum, both resulting in less milk being expressed.
- Nipple Damage and Irritation: Incorrect flange sizes can cause nipple trauma, including soreness, bruising, and even cracked nipples.
- Clogged Ducts: Inefficient milk removal due to an ill-fitting flange can contribute to clogged milk ducts, a painful condition that can disrupt your breastfeeding journey.
Choosing the correct Medela flange size, guided by a Medela flange size guide, ensures comfortable, pain-free pumping and optimal milk production.
How to Measure Your Medela Flange Size
Finding your correct Medela flange size starts with measuring your nipple. It’s important to measure only your nipple and not include the areola (the darker area around your nipple). Here’s how to measure accurately:
- Gather your tools: You’ll need a ruler or a fabric measuring tape with millimeters clearly marked. A mirror can also be helpful.
- Measure after pumping: Nipples can swell slightly after pumping, so it’s best to measure shortly after a pumping session when they are closer to their usual size.
- Measure the base of your nipple: Place the ruler or measuring tape across the base of your nipple at its widest point. Measure in millimeters (mm). Do this a couple of times to ensure accuracy.
- Measure both nipples: Nipple sizes can vary slightly, so measure both and use the larger measurement to determine your flange size.
Remember, your flange size can change over time, especially in the early weeks postpartum as your body changes. It’s a good idea to remeasure periodically to ensure your flange size remains optimal.
Medela Flange Size Chart: Finding Your Fit
Once you have your nipple measurement, you can use the Medela flange size guide to determine your starting flange size. A general rule of thumb is to add 4mm to your nipple measurement. However, Medela provides specific guidance for their flanges. Here’s a general chart based on common recommendations:
| Nipple Measurement (mm) | Recommended Flange Size (mm) | Medela Flange Recommendation (Consider) |
|---|---|---|
| 13-16mm | 17mm | 21mm PersonalFit Flex™ or 21mm PersonalFit™ |
| 17-20mm | 21mm | 24mm PersonalFit Flex™ or 24mm PersonalFit™ (Standard Size) |
| 21-24mm | 24mm | 27mm PersonalFit Flex™ or 27mm PersonalFit™ |
| 25-28mm | 28mm | 30mm PersonalFit Flex™ or 30mm PersonalFit™ |
| 29-32mm | 32mm | 36mm PersonalFit Flex™ or 36mm PersonalFit™ |
Important Note: This chart is a starting point. Medela offers various flange types, including PersonalFit™ and PersonalFit Flex™. The PersonalFit Flex™ flanges are designed with a more flexible rim and oval shape, which may provide a better fit for some mothers. Always refer to the specific Medela flange size guide that comes with your pump or consult Medela’s website for the most accurate and up-to-date recommendations.
How to Determine if Your Medela Flange Fits Correctly: The COMFY Test
Beyond just measurements, the feeling and appearance during and after pumping are crucial indicators of a correct flange fit. Many lactation consultants recommend the “COMFY” test to assess flange size. This is particularly helpful when using Medela flanges.
C – Center Nipples Move Freely: Your nipple should be centered in the flange tunnel and move freely without rubbing against the sides. Excessive rubbing can cause pain and irritation.
O – Only a Little Areola Tissue Should be Pulled Into the Tunnel: Ideally, only your nipple should be drawn into the flange tunnel. A small amount of areola is acceptable, but if a large portion is pulled in, the flange is likely too big.
M – Motion of Your Breast is Gentle and Rhythmic: Your breast should move gently and rhythmically with the pump’s suction. There shouldn’t be any tugging or pulling sensations.
F – Feels Comfortable Breast Pumping: Pumping should not be painful! Some suction sensation is normal, but sharp pain, pinching, or significant discomfort indicates an incorrect flange size.
Y – Yields Well-Drained Breasts: After pumping, your breasts should feel softer and emptier. If your breasts still feel full after pumping for a reasonable duration, an incorrect flange size could be hindering milk flow.
If you experience any pain, notice excessive areola being drawn in, or feel your breasts are not draining well even after checking your pump settings, re-evaluate your Medela flange size.
Medela PersonalFit Flex™ Breast Shields: Designed for Comfort and Efficiency
Medela is renowned for its commitment to innovation and mother’s comfort. Their PersonalFit Flex™ Breast Shields exemplify this. These flanges are designed with:

When considering Medela flanges, exploring the PersonalFit Flex™ range is highly recommended, especially if you are experiencing discomfort or struggling with milk output. They represent Medela’s advanced approach to breast pumping technology, focused on both comfort and efficiency.
Conclusion: Finding Your Ideal Medela Flange Size for a Successful Pumping Journey
Choosing the correct Medela flange size is a vital step towards a comfortable and successful breast pumping experience. By understanding how to measure your nipple, using a Medela flange size guide, and paying attention to comfort cues with the COMFY test, you can identify the best flange size for you. Remember, finding the right fit might involve some experimentation, and it’s perfectly normal to need a different flange size than the standard one included with your pump. Don’t hesitate to reach out to a lactation consultant or consult Medela’s resources for personalized guidance to ensure your pumping journey is as comfortable and productive as possible.
