Measure and Cut Carpet Tread

What happens in this clip

Using a tape measure, accurately measure the width of the stair tread where the carpet will sit. The installer measures 12.5 inches. He then decides to add a half-inch to the measurement, cutting the carpet to 13 inches, to ensure a very snug fit, noting that a previous piece was 'a little tight.' Unroll the carpet and use scissors to carefully cut a straight line across the carpet, following the measured width.

Goal: Prepare a carpet piece of appropriate size for the stair tread.

Step 2 of 5: Measure and Cut Carpet Treads

Using a measuring tape, carefully measure the length and width of each metal stair tread. Transfer these measurements to the carpet tread material. Use a sharp utility knife or carpet shears to cut each tread to size. It's often helpful to cut a template from paper or cardboard first to ensure accuracy before cutting the carpet. For spiral stairs, pay close attention to the curve and the outer edge.
