A stair runner is a practical and stylish way to enhance your staircase. It adds warmth underfoot, improves safety by reducing slips, and can completely change the look of your hallway or landing. With careful preparation and the right approach, fitting a stair runner can be a successful DIY project.
This guide explains how to fit a stair runner step by step, helping you achieve a neat and long-lasting finish.
What Is a Stair Runner?
A stair runner is a strip of carpet fitted down the centre of a staircase, leaving the edges exposed. They are available in a wide range of materials, colours, and patterns to suit both modern and traditional interiors.

Step 1: Measure Your Stairs
Accurate measurements are essential.
- Measure the width of your staircase
- Decide how much stair you want visible on each side
- Measure the depth of each tread and the height of each riser
- Multiply this measurement by the number of steps
- Add extra length for trimming and adjustments
Taking time to measure correctly will help prevent waste and ensure a neat finish.
Step 2: Prepare the Staircase
Preparation is key to a professional-looking result.
- Remove any existing carpet, staples, or nails
- Clean the stairs thoroughly
- Fix any loose or squeaking steps
- Lightly sand wooden stairs if needed.
This is also a good opportunity to paint or varnish exposed stair edges if desired.
Step 3: Fit the Underlay (Optional)
Underlay adds comfort and helps extend the life of your stair runner.
- Cut the underlay to the same width as the runner
- Fix it securely to each tread
- Avoid wrapping underlay over the stair edge
Step 4: Mark Your Guidelines
Use a pencil or chalk to mark a straight guideline down the centre of the staircase. This will help keep the runner aligned as you work your way down.
Step 5: Start Fitting at the Top
- Position the runner at the top of the stairs
- Make sure it is centred and straight
- Staple the top edge securely beneath the stair lip
- Work from the centre outwards
Step 6: Secure Each Step
For each stair:
- Pull the runner firmly over the tread
- Push it tightly into the corner where the tread meets the riser
- Staple along the crease
- Secure underneath the stair nose
- Check alignment before moving to the next step
Using enough staples is important to keep the runner safe and secure.
Step 7: Finish at the Bottom
- Trim any excess carpet neatly
- Fold the edge under for a clean finish
- Staple securely
- Tap down visible staples with a hammer
Optional: Add Stair Rods
Stair rods are a decorative feature often used with traditional stair runners.
- Fit them at the base of each riser
- Ensure they are evenly spaced and level
- Install after the runner is fully fitted
Safety Tips
- Keep fingers clear when using a staple gun
- Wear knee protection for comfort
- Take your time—rushing can lead to mistakes
- Consider professional help for curved or uneven staircases
