Measure and Cut Carpet

What happens in this clip

Measure the width of the stair tread from stringer to stringer (e.g., 36 1/8 inches) and the depth from the nose to the back riser (e.g., 13 inches). To allow for trimming and a snug fit, cut the carpet pieces slightly larger than these measurements (e.g., 37 inches wide by 14 inches deep). Use a utility knife and a straight edge to ensure clean, straight cuts. You will need one carpet piece per tread.

Step 2 of 6: 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.
