How to Measure Your Nail Size
1. Place a piece of tape across the widest part of your nail and press it down to follow the curve.
2. Mark the edges of your nail on the tape using a pen.
3. Remove the tape and place it on a flat surface. Measure the distance between the two marks in millimeters (mm) using a ruler or measuring tape.
4. Repeat for all 10 fingers.
