Vanliga frågor och svar om detta verktyg.

The stringer is the hypotenuse of a right triangle formed by total rise and total run, so length = sqrt(rise² + run²) per the Pythagorean theorem.
A minimum of 2 stringers (one per side) is required; stairs wider than 36 in typically need a center stringer added for every additional 36 in of width.
