Prepare Your Nails
Measure Width in Millimeters
Record Your Sizes
Compare to Our Chart
Ensure nails are bare and clean. Use a flexible measuring tape or a small piece of clear tape and a fine-tip marker for accuracy. Focus on the widest part of each nail.
Note down the millimeter measurement for each nail, starting from thumb to pinky. This ensures you have a precise record for every finger, guaranteeing a flawless application.
Once you have all ten measurements, compare them to our standard size chart to find your corresponding ArcNails size (XS, S, M, L) or input custom millimeter dimensions.
Place the tape across the widest point of your natural nail bed, from sidewall to sidewall. Mark the edges on the tape, then measure the distance in millimeters with a ruler. Repeat for all ten fingers.
ArcNails Sizing Categories
Our standard sizes (XS, S, M, L) are carefully curated to fit a wide range of natural nail beds. Each category corresponds to specific millimeter measurements across your thumb, index, middle, ring, and pinky fingers. Refer to our detailed chart for exact dimensions.
