How to Measure Your Nails

For the best fit, measure the widest part of each natural nail and compare your measurements with our size chart.

Method 1: Measure with a Soft Measuring Tape

Wrap a soft measuring tape across the widest part of your nail, following the natural curve from one side to the other.

Record the measurement in millimeters (mm) and repeat for all 10 nails.

Method 2: Measure with Paper

Wrap a small strip of paper across the widest part of your nail.

Mark where each side of your nail meets the paper.

Lay the paper flat and measure the distance between the two marks with a ruler.

Record the measurement in millimeters (mm) and repeat for all 10 nails.

Tip: If your measurement falls between two sizes, choose the larger size and gently file the sides for a custom fit.
