How to Measure Breast Pump Flange Size: A Comprehensive Guide

Why Flange Size Matters

When it comes to breastfeeding, comfort and efficiency are paramount. One of the most overlooked yet critical components of a breast pump is the flange. The flange is the part of the breast pump that fits over the nipple and areola, creating a seal that allows the pump to express milk. If the flange size is incorrect, it can lead to discomfort, reduced milk output, and even damage to the breast tissue. Therefore, knowing how to measure breast pump flange size is essential for every breastfeeding mother.

Understanding Flange Size

Flange size is determined by the diameter of the nipple, not the breast. The standard flange sizes range from 21mm to 36mm, but some women may require sizes outside this range. A flange that is too small can compress the nipple, causing pain and restricting milk flow. Conversely, a flange that is too large can pull in too much of the areola, leading to discomfort and inefficient milk expression.

Step-by-Step Guide to Measuring Flange Size

Step 1: Gather Your Tools

To measure your flange size, you will need a flexible measuring tape or a ruler. Some women also find it helpful to have a mirror on hand to ensure accurate measurements.

Step 2: Measure Your Nipple Diameter

After breastfeeding or pumping, measure the diameter of your nipple at its base. Make sure to measure only the nipple, not the areola. This measurement should be taken in millimeters.

Step 3: Add 3-4mm to Your Nipple Diameter

Once you have your nipple diameter, add 3-4mm to determine your flange size. This additional space allows for comfortable movement of the nipple during pumping.

Step 4: Test the Fit

After determining your flange size, test the fit by using the breast pump. Your nipple should move freely within the tunnel of the flange without rubbing against the sides. If you experience discomfort or notice that your nipple is not moving freely, you may need to adjust the size.

Common Issues and Troubleshooting

Pain During Pumping

If you experience pain during pumping, it could be a sign that your flange size is incorrect. Re-measure your nipple diameter and adjust the flange size accordingly.

Reduced Milk Output

A flange that is too large or too small can reduce milk output. Ensure that your flange size allows for efficient milk expression by following the measurement guidelines.

Nipple Swelling or Damage

Nipple swelling or damage can occur if the flange size is incorrect. If you notice any signs of damage, stop using the pump immediately and consult a lactation consultant for further guidance.

When to Seek Professional Help

If you are unsure about your flange size or continue to experience issues despite adjusting the size, it may be helpful to consult a lactation consultant. They can provide personalized recommendations and ensure that you are using the correct flange size for your needs.

Final Thoughts

Measuring your breast pump flange size is a simple yet crucial step in ensuring a comfortable and efficient pumping experience. By following the steps outlined in this guide, you can find the perfect fit and avoid common issues associated with incorrect flange sizes. Remember, the right flange size can make all the difference in your breastfeeding journey.
