How to Choose the Right Flange Size

Selecting the correct flange size for your breast pump is key to a comfortable and efficient pumping experience. The flange—the part of the pump that comes into contact with your breast—directly affects milk flow, comfort, and overall effectiveness. In this guide, we’ll walk you through the importance of proper flange sizing, how to measure your size, and how to adapt if adjustments are needed.

Why Is Flange Size Important?

The flange size determines how well the pump fits your breast. A properly sized flange ensures:

• Comfort: Prevents pain or irritation during pumping.
• Optimal Milk Flow: Reduces blockages and allows for efficient milk expression.
• Healthy Breast Tissue: Minimizes stress on the nipple and surrounding area, reducing the risk of soreness or clogged ducts.

On the other hand, an incorrect flange size can lead to:

• Pain or Discomfort:A flange too small may pinch, while one too large can pull in excess areola tissue.
• Reduced Milk Output: Improper sizing can restrict milk flow or create an ineffective suction.
• Prolonged Pumping Time: Inefficient pumping sessions can be time-consuming and frustrating.

How to Measure for the Right Flange Size

Measuring your nipple is the first step toward finding your ideal flange size. Follow these simple steps:

1. Measure After Feeding or Pumping: This ensures your nipple is at its natural size, as it may temporarily swell during or after use.
2. Use a Measuring Tool: A ruler or tape measure works well. Measure the diameter of your nipple (not including the areola) in millimeters.
3. Add 1-2 Millimeters: This extra space allows the nipple to move freely within the flange tunnel without rubbing or causing discomfort.

Most breast pump flanges come in standard sizes, typically ranging from 21mm to 27mm. If your nipple size falls between two standard options or changes over time, consider using flange inserts to adjust the fit for optimal comfort.

Signs That You May Be Using the Wrong Size

Even with careful measurement, it’s possible to discover that your flange size isn’t quite right. Here are some common signs:

• Flange Too Large: Your areola is pulled into the flange tunnel along with the nipple, causing discomfort or inefficient suction.
• Flange Too Small: Your nipple rubs against the sides of the flange, resulting in pain, redness, or irritation.
• Reduced Milk Flow: Pumping takes longer, or you’re unable to express as much milk as usual.

If you notice any of these issues, reassess your flange size. Adjustments, such as using inserts, can make a significant difference.

Adjusting to Changes in Nipple Size

Breastfeeding is a dynamic process, and your nipple size may vary due to factors like hormonal changes, feeding frequency, or milk production levels. Regularly reassessing your flange size is important to ensure continued comfort and efficiency.

For mothers experiencing fluctuating sizes, flange sizing kits are a helpful solution. These kits allow you to try different sizes, ensuring you find the most comfortable and effective fit for your changing needs.
