Measure and Cut Carpet Sections

What happens in this clip

For the actual carpet, carefully measure the width of the stairs from wall to wall. Since stairs may not be perfectly straight (especially in older homes in the UK), measure at different points (e.g., at the back and front of the step) and use the biggest measurement. Then, add 3-4mm (approximately 1/8 inch) to this largest width. This extra allowance ensures the carpet can be properly tucked down the sides. For the length, measure the depth of the tread and the height of the riser, similar to the underlay. To make handling easier, cut the carpet into manageable sections (e.g., 1-meter sections) from the main roll before making the final cuts for each individual step. Ensure a straight edge is maintained for all cuts.

Goal: Prepare carpet sections for all stairs

This project provides a comprehensive guide on how to fit your own stair carpet. It covers essential steps from measuring and cutting carpet grippers and underlay to installing them securely, and finally fitting the carpet itself, ensuring a professional and neat finish for a DIY enthusiast.

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.
