How to Measure Your Nails
Coin Method (Photo Measurement) - Recommended
- Place a dime (U.S. or similar coin) on a flat surface.
- Lay your fingers (and then thumb) flat beside the coin.
- Take a bird’s-eye photo ensuring coin and nails are on the same plane.
- Send the images to us—we'll use the coin to calculate the size accurately.
Measuring-Tape Method: Best with a flexible tape measure
- Use the millimeter side of a soft measuring tape.
- Wrap it across the widest part of your nail plate.
- Read and record the measurement in millimeters.
- Repeat for all ten nails—each fingertip is a different size!
Sticky-Tape (Ruler) Method: Ideal if you don’t have a flexible tape
- Stick a small strip of clear tape to your nail, pressing it down firmly.
- Mark the tape edges with a pen right where your natural nail ends.
- Remove the tape and lay it flat.
- Measure between markings on a ruler in mm and note each size.
Multi-Size Try-On Kit: Best for standard, size-graded sets
- Hold each pre-sized press-on against your natural nail before applying glue.
- Look for a fit that hugs the nail plate, isn’t too tight, and doesn’t press into skin.
- If in doubt, choose the larger size—then gently file it down to fit.
