How to Measure Size for Spectra Baby Breast Shield Flange?
Choosing the right size for the Breast Shield Flange is necessary. Right size for breast shield can achieve:
- Comfortable pumping sessions

Steps to Measure Breast Shield
- When it comes to breast pumping, the size of your nipple must be properly measured for best results when selecting spectra flanges.
- Find your nipple size: After measuring, add 3-4mm to find your flang size. For example, if you measure 16mm, your breast flang size is 19-20mm.
- Avoid large fit: A flang that is too large can cause discomfort, pain & swelling when using spectra flanges.
- Avoid small fit: A flang is too small when your nipple touches or rub against the tunnel wall of the flang, or no suction occurs.
- Locate the best fit: When pumping with the right size flange, your nipple moves freely in the flange tunnel and not much of the areola is drawn into the tunnel.
