Complete Guide to Spectra Flange Sizes
As a mother and breast pump expert, I’m here to help you find the perfect flange fit for comfortable and effective pumping with your Spectra breast pump.
After years of testing and reviewing breast pumps, I can confidently say that finding the right flange size is absolutely crucial for your pumping success. I’ve personally experienced the discomfort of using the wrong size, and I’ve helped countless mothers through my website find their perfect fit. Let me share everything I’ve learned about Spectra flange sizes.
Why Flange Size Matters for Your Pumping Journey
From my experience with different breast pumps, including extensive testing of the Spectra S1 Breast Pump, I’ve seen how the wrong flange size can make or break your pumping experience.
🌸 My Personal Experience
When I first started pumping, I used the standard 24mm flanges that came with my pump. I experienced pain, reduced milk output, and even developed sore nipples. Once I switched to the correct 21mm size, everything changed – pumping became comfortable and efficient!
Step-by-Step Guide to Finding Your Perfect Flange Size
Understand Your Nipple Shape
Before measuring, I always tell mothers to understand that nipples come in different shapes – some are round, others are oval or elastic. This affects how they respond to pumping suction.
Gather Your Measuring Tools
You’ll need a ruler or measuring tape with millimeter markings. I recommend measuring after a warm shower when your nipples are in their natural state.
Measure Your Nipple Diameter
Measure across the base of your nipple, not including the areola
As shown in the image above, measure across the widest part of your nipple base. Don’t include the areola – focus only on the nipple itself. Take this measurement when you’re not aroused or cold, as these states can affect nipple size.
Add 2-4mm for Comfort
Based on my testing and research, I recommend adding 2-4mm to your nipple measurement. This allows for slight swelling during pumping and ensures comfort.

Signs You Need a Different Flange Size
🚨 Too Small Flange Signs:
From my experience helping mothers, here are the telltale signs your flange is too small:
- Your nipple rubs against the tunnel walls
- Pain during or after pumping
- White or purple discoloration of nipples
- Reduced milk output over time
- Nipple damage or cracks
📏 Too Large Flange Signs:
- Areola tissue being pulled into the tunnel
- Inefficient milk removal
- Longer pumping sessions with less output
- Breast tissue being pulled into the flange

Where to Buy Spectra Flanges
I recommend purchasing directly from Spectra or authorized retailers to ensure you’re getting genuine parts. Avoid cheap knockoffs – they can affect your pumping efficiency and comfort.

Buy flanges in sets of 2-3 so you always have clean ones ready. I also suggest getting one size smaller and one size larger than your measured size for comparison.
