Size Guide
Find your perfect fit
How to Measure
1
Remove any polish or press-ons. Push back cuticles gently so the full nail bed is visible.
2
Place a piece of clear tape across the widest part of your nail (side to side).
3
Mark both edges of your nail on the tape with a pen.
4
Remove the tape, lay it flat, and measure between the marks with a ruler (in mm).
5
Repeat for all 10 fingers — both hands! Your dominant hand may be slightly wider.
Between sizes? Always size up! You can file down for a perfect fit, but you can’t add material back.
