NaillyTip depth is the hidden variable of every French manicure: the same design reads minimalist at two millimetres and editorial at a third of the nail. Salons increasingly treat it as a booked specification rather than an improvisation, and design tools now let you set it explicitly.
Rules of thumb: short nails favour micro; deep tips give art (chrome, glitter fades, colour) room to perform and hide tip-wear longest; classic is classic for a reason.
