A method for controlling rope sway in an elevator is provided. In the first step a car is provided for travel in a hoistway, wherein the hoistway includes a pair of opposed vertically extending walls between which the car travels. The car includes a center of gravity having an x coordinate and a y coordinate. In the second step, a counterweight is provided for traveling between the hoistway walls. The car and the counterweight are connected to one another by a plurality of ropes. In the third step, a first number of ropes are attached to the car a distance away from the x coordinate of the car. In the fourth step, a second number of ropes are attached to the car a distance away from the x coordinate, equal to the distance the first number of ropes are away from the x coordinate, on the opposite side of the x coordinate as the first number of ropes. The distance the ropes are attached away from the x coordinate is great enough such that oscillation of the ropes will cause the ropes to contact the wall adjacent to the ropes and thereby limit the magnitude of the oscillation.
