What happens in this clip
Measure the width and depth of each stair tread using a tape measure. Use these measurements to cut individual pieces of 'Stainmaster carpet cushion' underlayment to fit each tread. Use a straight edge and a sharp utility knife for precise cuts. The underlayment should cover the flat surface of the tread, extending just to the tack strip at the back and slightly over the stair nose.
Goal: Prepare underlayment pieces for each stair tread

Step 2 of 6: Measure and Mark Carpet Treads
Using a measuring tape, carefully measure the width and depth of each individual porch step. For each step, mark these dimensions onto the back of the carpet tread material. It's often helpful to mark a cutting line slightly larger than the step's dimensions to allow for a small overhang or to trim down for a perfect fit.
