How to Measure Your Flange Size？

In the field of breast pumps, the flange plays a pivotal role, yet its significance is often underestimated. A flange, sometimes referred to as a breast shield, is the component of the breast pump that directly contacts the breast. Its primary function is to create a vacuum seal around the nipple, facilitating the extraction of milk from the breast to the bottle. The right flange size is essential for several reasons: it ensures comfort during pumping, maximizes milk flow, and prevents potential nipple trauma.

Understanding the anatomy of a flange and its operational mechanics is the first step toward a comfortable and efficient pumping journey. As we progress, the importance of personalized flange sizing will become increasingly clear, underscoring the need for every pumping mom to find her perfect fit.

Selecting the right flange size is more than a matter of comfort; it's crucial for effective milk extraction and breast health. A size too small can lead to nipple irritation or blockage of milk ducts, while a size too large can decrease milk production and cause unnecessary discomfort. Proper flange fit ensures that the nipple moves freely within the flange tunnel during pumping, enhancing the efficiency of milk flow and mimicking the natural breastfeeding rhythm as closely as possible.

Measuring your flange size accurately is essential for a comfortable and efficient pumping experience. Follow these steps to find your perfect fit: Measure Your Nipple: Without including the areola, measure the diameter of your nipple in millimeters (mm). This can be done using a ruler or a measuring tape, preferably after a pumping session when your nipple is more likely to be in its expanded state.

Add Extra Millimeters: To the measurement obtained, add 2-4mm to accommodate the natural expansion of the nipple during pumping. This ensures that the nipple can move freely within the flange tunnel, enhancing comfort and effectiveness. To more accurately select the breast pump flange size that suits you, we provide users with a more convenient Flange Measuring Tool. By following these steps, you can ensure that you select a flange size that provides the best fit for your body, minimizing discomfort and maximizing your breast pumping efficiency！
