Step-by-Step Guide to Install Carpet on Stairs

Carpeting your staircase not only adds comfort but also brings a touch of elegance to your interior décor. Whether you choose to cover each stairway tread or only specific steps, adding carpet can transform the look and feel of your stairs.

Install carpet on a stair or stairway might initially seem daunting, but this step-by-step guide will demystify the process and help you quickly navigate each tread.

1.Gather Your Materials

The first step to installing a carpet is to gather all your materials, including the carpet, carpet padtackless stripsstaple gunmeasuring tape, staples, tread, stair runner, and stair riser.

You will also need essential utility tools such as staples, paint, a sharp pencil, a knife, safety glasses, and gloves. These items are vital for completing the necessary steps in your project.

Consider using a knee kicker to achieve a snug fit for your carpet, especially if installing a runner rug. While this tool is optional, it can help secure the mat onto the tackless strips and ensure a tight fit on each riser and tread.

Gather Your Materials

When choosing a carpet for your staircase, it’s essential to consider aesthetics and durability. Stairs are high-traffic areas, so you want a rug that can withstand wear and tear.

If you decide to use a knee kicker, it will aid you in stretching the runner rug over the staircase steps to avoid any unsightly bulges or creases on the risers.

2.Prepare the Stairs

After gathering your materials, it’s time to prepare your stairs for the new carpet. Remove any old carpet or padding from the staircase to provide a clean surface for the new rug. Make sure to check the steps, tread, riser, and strips.

Then, clean the staircase using a mild soap and water solution, thoroughly cleaning all dust, dirt, grime, steps, treads, and carpet runner.

It’s crucial to let the staircase tread dry thoroughly after cleaning, as any moisture could negatively affect the runner rug adhesive and the overall longevity of the step.

3.Cut the Carpet Pad to Size

Your carpet padding is the cushioning that protects your carpet from premature wear. To ensure a perfect fit for your runner rug, measure each step individually before cutting the padding for your staircase.

Cut the Carpet Pad to Size

The runner rug pad should fit precisely between the tackless strips you’ll install later on the staircase, covering the area between the back of the tread and the bottom of the riser. Precise measurements and cutting prevent unevenness and bulges in the carpet later on the stairs.

4.Apply the Carpet Pad

The next step in applying a staircase runner rug is to cut your pad to the exact size. Begin at the top of the stairs and staple the carpet pad to the back of each tread, ensuring to pin every 6 to 8 inches

Stretching the carpet runner cushion tightly as you fasten it down would be best to prevent any wrinkles or movement on the stairs after the installation.

5.Cut the Carpet to Size

Before installing, you must cut the carpet tread to size. Like the carpet pad, measure each staircase step individually and cut the rug runner to match.

Extend the runner rug 2 inches beyond the front edge of each step on the staircase for an easy installation and a cleaner finish, and 1 inch beyond the bottom of each riser.

6.Install the Tackless Strips

Tackless strips are a crucial part of the carpet installation process as they help keep the carpet securely placed on stairs. Whether you have a tread or runner rug, using tackless strips ensures the carpet stays in position with every step

To install a runner rug on stairs, measure and cut the tackless strips to match the width of each step. You must nail the ribbons to the back of each riser, 1 inch from the top edge. This placement ensures a firm grip on the carpet during and after the process.

7.Staple the Carpet in Place

Now, you can easily place the carpet on the stairs following the above steps. You must staple the rug every 6 to 8 inches as you attach the carpet padding to tackless strips. Stretching the carpet tightly as you pin it in place is crucial to avoid lumps or loose areas. Properly align the tread and riser with the runner, ensuring a secure and clean installation.

8.Finish the Edges

Once you complete the installation step, fold the excess runner under the nosing of each tread and staple. If your stairs have open risers, you can fold the extra strips over the riser and staple it down; this gives your stairs a clean and finished look.

9.Clean Up

With the runner rug securely in place, the final step is clean-up. Remove any visible staples, and sweep or vacuum up any debris. Cleaning up after the installation lets you thoroughly appreciate your newly carpeted stairs‘ tread.

10.Enjoy Your New Carpeted Stairs!

After all your hard work, take a step back and admire your finished product! The comfort and aesthetic of your new carpeted stairs, with the tread, runner rug, riser, and v4, are something to be enjoyed and celebrated.


The above step-by-step instruction is a general outline to install carpet on typical stairs, including specific situations such as using a runner rug or a riser. However, you may need additional factors for particular conditions, such as using the v4 model.

1.Installing Carpet on a Curved Staircase

When installing carpet on a curved staircase, creating a template for each step is essential; this will ensure that the rug aligns perfectly with the contours of the stairs. Using a template, you can accurately cut the carpet and achieve a snug fit and professional finish. This method is beneficial for stairs with a v4 riser design.

2.Installing Carpet on Staircase with Open Risers

Use a carpet runner instead of a full-width carpet for v4 staircases with open risers. A runner will save you the trouble of folding and stapling the rug at the back of each step, which can be difficult and may not result in the desired aesthetic.

3.Hire a Professional

If you feel uncomfortable or overwhelmed with installing the runner rug on your stairs, remember you can always hire a professional. Carpet installation on stairs requires expertise, and a professional can ensure a flawless and smooth finish on each step and riser, saving you time and potentially unnecessary expenses.


Mastering the art of carpet installation on stairs can be a manageable task with proper preparation and a step-by-step approach. This guide on installing carpet on stairs, including a runner rug, has provided detailed instructions and tips for handling unique situations like using a riser. While the DIY route can be satisfying and cost-effective, hire a professional if you feel the task is beyond your skill level. The goal is a comfortable, safe, and stylish staircase for your home!
