Abstract
A nail gauge tool is provided for quickly and accurately measuring nail shape and nail size. The nail gauge offers several arch-shaped openings for matching to and measuring a natural nail. As the measurement result, the nail arch shape information and nail arc length information along the natural nail's width direction are obtained for manufacturing custom-fit artificial nails. The nail gauge tool is advantageously small and suitable for use inside a nail salon.
