Soft measuring tape
Follow the natural curve across the widest part of the nail bed. Read and record the width in millimeters without squeezing the nail.
THE FIT EDIT
Ten nails.
One precise fit.
Measure the natural curve of every nail at its widest point, then choose the standard set closest to your measurements.
Widest point
01
Measure the curve—not a straight line across the top.
MEASURE AT HOME
Two easy methods.
Measure both hands in millimeters before ordering. A five-minute fit check helps avoid pinching, gaps, and exposed sidewalls.
Paper or clear tape
Wrap a narrow strip across the widest point, mark both sidewalls, then lay it flat against a millimeter ruler.

Measurements below are the nail-bed widths supplied with the product packaging. Inch values are rounded for convenience.

1 mm = 0.0394 in. Because inch values are rounded, use millimeters when choosing a set.
HOW TO CHOOSE
Match the majority.
Refine the rest.
Compare all ten measurements with the chart. Choose the row that fits the greatest number of your nails, then follow these fit rules.
Measure both hands—corresponding nails can differ slightly.
The press-on should cover the nail from sidewall to sidewall without touching skin.
If you fall between two sizes, choose the larger size and gently file the sidewalls.
BETWEEN TWO SIZES?
Choose the larger one.
A slightly wider press-on can be refined with a fine nail file. A size that is too narrow can pinch, leave the natural nail exposed, or lift at the sidewalls.
