How to measure
Measure your nails at home.
You'll need a strip of paper, a ruler and a pen. It takes about three minutes.
- 1.Wrap a thin strip of paper across the widest part of your natural nail.
- 2.Mark where the paper meets itself with a pen.
- 3.Lay the paper flat and measure that distance in millimeters with a ruler.
- 4.Repeat for each finger — your nails will likely be different sizes.
- 5.Match each measurement to the closest size in the width chart.
