Step 1: Measure the Width of Each Nail
Prepare Your Tools: If you're using a flexible measuring tape, ensure it's clean and free of any folds. If using tape and a ruler, cut a small piece of tape.
1. Place the measuring tape across the widest part of your nail, typically the middle. If using tape, place it across the widest part of your nail and mark where the edges of your nail are on the tape.
2. Use the ruler to measure the distance between the marks.
3. Record the Measurement: Write down the measurement for each nail in millimeters (mm). Start with your thumb (1) and work your way to your pinky (5). Repeat for the other hand.
