Place a soft measuring tape flat across the widest part of your nail. Pull it tight to account for any curves, then record the width of each nail in millimeters.

OR

Step 1: Place a piece of tape across the widest part of your nail, pressing it down to follow the curve. Mark the edges of your nail on the tape with a pen. Remove the tape, place it on a flat surface, and measure the distance between the marks in millimeters using a ruler or measuring tape. Repeat for each nail.

Step 2: Use the measurements to find your nail size (00-9) using the chart below, then select the corresponding size kit (XS, S, M, L, XL).

Important:

  • If you're between sizes, size up and file down for a better fit.

  • If your measurements don’t match standard sizes, choose “Custom” at checkout and enter your sizes in this order: Thumb, Index, Middle, Ring, Pinky (e.g., 2, 4.5, 4, 6, 8).
