Measuring Tape Method

  1. Make sure to use the centimeter side of your measuring tape.
  2. Wrap the measuring tape around the widest part of your nail. 
  3. Line the tape’s 0 line with one side of your nail, and count the millimeter lines to see how wide it is. 
  4. Don’t forget to write down the width of each nail! 
  5. Measure the nails on both hands, as there can be some variation.


Straight Ruler and Sticky Tape

  1. Apply a small strip of sticky tape to your nail, making sure to press it down completely so it’s completely attached without gaps or bubbles. 
  2. Using a pen or marker, draw two lines to mark the width of your nail. 
  3. Remove the sticky tape, and lay it down flat on a piece of paper. 
  4. Using the ruler, measure the tape by millimeters, and record the number. 
  5. Continue for all nails.
