Step 3 · Tackle the Corner: Landings vs. Winders

This is where your observation from Step 1 pays off. If you have a landing (a flat platform): Measure its full width and length to be treated as one large rectangular piece. For safety and proper coverage, this landing area must be at least 36 inches deep and as wide as the stairs leading to it. If you have winder steps (angled, wedge-shaped): These require individual attention. For each winder tread, you must measure its depth, the length of its narrow inner edge (near the turn), and the length of its wide outer edge. Taking these precise measurements is the secret to achieving that seamless, professional look where safety meets style on every part of your staircase.
