Step-by-Step Measuring Instructions
1. Measure Your Nipple Diameter
Measure across the base of your nipple (not the areola) at its widest point. This should be done when your nipple is at rest, not erect.
2. Add 2-4mm for Comfort
Your nipple shield should be 2-4mm larger than your nipple diameter to allow for comfortable movement and prevent friction.
