A clear measure before a better fit.

Measure the widest point of each natural nail in millimeters. Keep the measuring tape or paper strip flat rather than following an exaggerated curve.

Compare each measurement with the final TALIAY chart. If a nail falls between two sizes, the larger option is usually easier to refine, but the approved product instructions will provide the final recommendation.

• Check both hands; matching fingers are not always identical.
• A nail should cover the natural nail without pressing painfully into the sidewalls.
• Final millimeter measurements will appear here after sample approval.
