When measuring your nails at home, I would recommend 3 methods:
Please remember to measure your nails in millimeters, thank you!
Method 1: Clear tape, a ruler, and pen
Step 1: Tape a piece of clear tape across your nail. Make sure to press the tape well on both sides of your nail.
Step 2: Mark the sides of your nail with a pen. Try to be as exact as you can.
Step 3: Stick the tape on a surface and measure.
Method 2: Measuring tape and pen
Step 1: Place the measuring tape across the widest part of your nail.
Step 2: Count each millimeter it takes to reach one end of your nail bed to the other.
Method 3: Purchase a sizing kit!
