Step 2: Measure the height of the banister. The narrow painted stripe, which mimics a chair rail, should be the same height. With a helper and using a laser level and the banister measurement, lightly mark points every two feet up the stairway wall. Use painter's tape to connect the marks; align the bottom of the tape on the marks, forming a diagonal line. Repeat, taping four or five inches below the top tape line.
