You measure a nail plate by using a ruler or measuring tape to determine its width, typically in millimeters.
The provided reference suggests a method for measuring the nail bed for press-on nails, which can be adapted to measuring the natural nail plate. Here's a breakdown:
- Tool: Use a ruler or flexible measuring tape that measures in millimeters.
- Placement: Place the ruler or measuring tape across the widest part of the nail plate.
- Reading: Note the measurement in millimeters. In the example, the measurement was 14 millimeters.
- In-Between Sizes: If the measurement falls between two millimeter marks, make a note of that as well.
