Find the size that feels made for you.
Measure the widest part of each natural nail in millimeters. Measure both hands, as nail sizes can vary between hands. Record your measurements in this order: Thumb / Index / Middle / Ring / Pinky, then compare them with the sizing chart below. If you fall between sizes, choose the larger size for the best coverage.
Measure in millimetersLay the tape flat and measure between the marks. Repeat for thumb, index, middle, ring and pinky.
Compare with the chartUse the preset that fits most closely. If a nail falls between sizes, sizing up gives you room to gently file the edge.
