1. Place & Mark

Apply a piece of clear, transparent tape across the widest part of your natural nail bed. Use a fine-tip pen or marker to place a clear dot on both the left and right sidewalls of your nail.

2. Measure in mm

Remove the tape carefully and lay it flat against a metric ruler. Measure the distance between the two dots in millimeters (mm) for exact precision.

3. Match Your Size

Repeat the process for all ten fingers (from thumb to pinky) and record each measurement.
