How to measure your nails

Use the illustrated fit profile below to record the width of all 10 nails. Measure your natural nail plate at its widest point, following its curve. Record both hands in millimeters (mm).

Fit profile: Tape it, stick it, mark it and check nail widths against the size chart
Trace each nail’s widest point, label every finger and compare the measurements against the chart below.

Measure the nail, not the full finger. If you are between two standard sizes, size up or choose Custom and provide both hands’ widths.
