A method and arrangement for aligning elevator guide rails includes measuring the position of two opposite guide rails in respect of the direction between guide rails (DGB) direction and the back to front wall direction (BTF) direction with a plumb line and a measurement device arranged at each guide rail. Each measurement device includes a guide shoe supported on at least two guide surfaces of the guide rail, a measurement frame connected to the guide shoe, and a sensor for sensing the position of the plumb line in respect of the measurement frame. The twist of the guide rails is measured with a wire extending between the two measurement devices and an edge sensor arranged in connection with at least one of the two measurement devices.
