Use a measuring tape to find the diameter of your nipple in millimeters. Measure the nipple alone, do not include the areola, which is the outer edge around your nipple. Add 2-3 mm to this measurement for your correct flange size.

A flange size guide helps you determine the correct breast pump flange (breast shield) size by measuring the diameter of your nipple in millimeters. The correct fit improves comfort and milk output.
Measure the diameter of your nipple (not the areola) in millimeters after a pumping session or when the nipple is stimulated. Then add 1–3 mm to determine your ideal flange size.
Use a ruler or nipple measuring tool to measure straight across the base of your nipple (excluding the areola). Record the diameter in millimeters.
After measuring your nipple diameter:
You would likely need a 16–18mm flange, depending on comfort and how your nipple responds during pumping.
Measure:
A firm ruler is best. If using measuring tape, ensure it is flat and measure straight across the nipple’s base in millimeters.
A nipple ruler is a measuring tool (often printable) with circular cutouts in millimeter sizes to help determine nipple diameter accurately.
