Step 2 · Measure and Mark Treads

Measure the width and depth of each individual stair tread. For most standard stairs, the depth will be from the nosing to the riser, and the width will be the span of the step. Transfer these measurements to the carpet treads, ensuring to account for any desired overlap or overhang. Use a chalk line or pencil to mark your cut lines clearly on the back of the carpet treads.
