Richtschnur

Richtschnur is a German term meaning a guiding line or reference line. It can denote a physical taut cord used to establish a straight reference when laying out work, or a figurative criterion or standard used to judge or guide actions.

In construction, carpentry and surveying a Richtschnur is a taut cord stretched between two points to transfer a straight line onto a surface. It helps align walls, edges and layouts and can be anchored with pegs or clamps. Traditional methods may use chalk lines to transfer the line, while modern sites frequently employ laser lines as alternatives.

In its figurative sense, a Richtschnur refers to a standard, benchmark or guideline that provides orientation for decisions or evaluations. It is not a binding rule but a reference point that shapes planning and assessment.

Etymology: the word combines richten, to set right or align, and Schnur, string. It has long been used in German-speaking contexts to denote both a physical line and a guiding principle.
