Step 2: Size the Runner

Measure and mark the centerline of the stairs on the narrowest tread, and line up the middle of the runner with the mark. (Conveniently, our runner has a stripe down the middle.) Use a tape measure to make sure the reveal on each side is even, then mark the tread at each edge of the runner, in pencil. Use a combination square to replicate the edge marks on each tread.
