Fitting a stair runner carpet can enhance the look of your stairs while adding safety and comfort. Here's a step-by-step guide on how to fit a stair runner carpet:




Tools and Materials You’ll Need:

  • Stair runner carpet (measure the length of your stairs)

  • Underlay (padding) for each step

  • Staple gun or carpet tacks

  • Carpet gripper rods

  • Hammer

  • Tape measure

  • Pencil

  • Utility knife or carpet cutter

  • Double-sided carpet tape

  • Straight edge or metal ruler

  • Knee kicker (optional but helpful)

  • Vacuum (to clean before and after installation)


Step-by-Step Guide to Fitting a Stair Runner Carpet:

1. Measure and Cut the Runner

  • Measure the width of your stairs and decide how wide you want the runner to be. Typically, a stair runner is narrower than the full width of the stairs, leaving a few inches of exposed wood on each side (e.g., 2-3 inches on each side).

  • Measure the length of the stairs, including the riser (the vertical part) and tread (the horizontal part) of each step. Multiply this by the number of steps to calculate the total length of carpet needed.

  • If your runner needs to be cut, use a utility knife and a straight edge for a clean cut.


2. Prepare the Stairs

  • Clean the stairs thoroughly to remove dust and debris.

  • If needed, install gripper rods. Place them about 1 inch from the back of the tread and the bottom of the riser for each step. The spikes should face the direction the carpet will be laid. Hammer the gripper rods into place.


3. Install the Underlay

  • Cut underlay (padding) to fit each step (covering the tread and the nosing or just the tread depending on preference).

  • Secure the underlay in place using double-sided carpet tape or a staple gun. Ensure the underlay is smooth, with no wrinkles, for an even surface under the runner.


4. Position the Runner

  • Starting at the bottom of the stairs, center the runner on the first step. Use a tape measure to ensure equal spacing on both sides.

  • Attach the bottom of the runner using double-sided carpet tape or staples on the underside of the riser, ensuring the runner is flush against the floor.


5. Staple the Runner in Place

  • Secure the runner at the top of the riser where it meets the tread using a staple gun. Place staples about 1-2 inches apart, ensuring the runner is firmly attached. Use a hammer to tap in any staples that don’t sit flush.

  • Pull the runner tightly over the tread and staple under the nosing (the edge of the step) to ensure a snug fit.


6. Continue Up the Stairs

  • Move up to the next step, pulling the runner tight over the next riser and tread.

  • Use a knee kicker if you have one, to stretch the carpet runner tightly into place.

  • Secure the runner at the top of each riser and under the nosing of each step, stapling it as you go.


7. Cut Excess Runner

  • Once you reach the top of the stairs, cut any excess runner using a utility knife. Ensure the cut is straight and neat.

  • Staple the end of the runner securely to the top of the last riser.


8. Finishing Touches

  • Check for wrinkles or loose sections. If necessary, pull the runner tight and add additional staples.

  • Vacuum the runner to remove any dust or loose fibers, and admire your work!


Tips for Fitting a Stair Runner Carpet:

  • Choose a durable material: Since stairs are a high-traffic area, select a hard-wearing carpet like wool or a blend for longevity.

  • Pattern placement: If your runner has a pattern, ensure it's aligned properly on each step.

  • Extra cushioning: Adding underlay gives the runner a plush feel and helps with noise reduction.

  • Staple placement: Place staples in the least visible spots, like the back of risers or underneath the nosing, for a clean look.


This DIY project can significantly upgrade the look of your stairs, and with patience and precision, you can achieve a professional-looking result!
