Size Guide

Find your perfect press-on fit

A great nail box starts with the right size. Measure at home in 2 minutes — then pick XS, S, M, L, or Custom on every product page.

How to measure

1. Use a soft tape or print a ruler at 100% scale.
2. Measure the widest part of each nail.
3. Write down all 10 widths in millimeters (thumb to pinky, both hands).
4. Match the chart below, or choose Custom Size and paste your mm note at checkout.
