How to Measure at Home
The secret to a perfect fit is accounting for the curve of your nail. Follow these steps for millimeter precision.
Apply Clear Tape
Place a piece of clear tape horizontally across the widest part of your natural nail bed. Press down firmly into the sidewalls to ensure the tape captures the natural curve of your nail.
Mark the Sidewalls
Using a fine-tip pen or marker, draw a line on the tape exactly where your nail meets the skin on both the left and right sides.
Measure on a Ruler
Carefully peel the tape off your nail and lay it completely flat against a millimeter (mm) measuring tape or ruler. Count the millimeters between your two pen marks.
Repeat & Record
Repeat this process for all 10 fingers, from Thumb to Pinky. Write down your measurements and use our interactive Size Finder above to get your perfect MLK fit!
