When it comes to using a breast pump effectively, selecting the correct flange size is crucial. This guide will help you navigate the various sizes available and determine which is best for you.

What Exactly is a Breast Pump Flange?

A breast pump flange is a funnel-like component that fits over the nipple, creating a vacuum seal around the areola. This design draws your nipple into the flange to facilitate milk extraction. Most pumps typically come with a standard flange size of 24 millimeters (mm), but they can range from 21 mm to 36 mm. The size refers to the diameter of the narrow edge of the flange, and you can obtain different sizes from your pump’s manufacturer, baby supply stores, or online platforms like Make a Mom.

Why is Flange Size Important?

Using the right flange size can significantly impact your pumping experience. An ill-fitting flange can result in discomfort and may hinder your ability to express milk efficiently. When the flange fits correctly, pumping can become a more manageable and less painful task.

Which Flange Size Should You Use?

To find the right size, consider measuring your nipple diameter and comparing it to the available flange sizes. This may require some trial and error, as personal comfort can vary.

How to Identify the Correct Flange Size

  1. Check for Comfort: If you’re experiencing pain or pinching, your flange may be too small.
  2. Observe Milk Flow: If milk is not flowing well, you may need a larger size.
  3. Look for Skin Discoloration: If your skin is turning white or red, that could signal a poor fit.

How to Tell if Your Flange is Too Big or Small

If the flange is too large, your nipple might move around too much within it, leading to inefficient milk expression. Conversely, a flange that’s too small can cause discomfort and may not effectively draw out milk.
