Step 3 · Width Wisdom: Ensuring a Stylish, Secure Fit
Next, let's capture the width of each tread. Run your tape measure across the front edge, making sure it’s perfectly parallel to where the tread meets the back riser. This ensures a true, straight measurement. Is your staircase embraced by walls on both sides? Then you'll measure from wall to wall. If one side is open, measure from the outer edge of the tread to the wall, or from edge to edge if both sides are open. For that classic, refined, and design-conscious look, we typically recommend leaving about a 1-inch space on each side of your carpet tread. So, for instance, a 36-inch wide stair would beautifully frame a 34-inch wide tread. This small detail makes a big difference in achieving a professional finish.
Measure wall-to-wall if your stairs are enclosed, or from edge to wall/edge-to-edge if one or both sides are open.
