Size Guide

Find Your Size

A careful measurement helps your claw nails sit comfortably and look balanced.

How to Measure

  1. Place a soft measuring tape across the widest part of your natural nail.
  2. Measure from sidewall to sidewall in millimeters.
  3. If you do not have a soft measuring tape, place a small strip of paper or clear tape across the nail, mark both sidewalls, then measure the marked distance with a ruler.
  4. Repeat for all ten nails and record the measurements in order.

Choosing a Standard Size

Measure both hands and compare the widest part of each natural nail with the chart below. All measurements are nail widths in millimeters. If you are between sizes, choose the slightly larger option and gently file the side edges for a closer fit.
