Carpeting stairs can be a challenging task, but it can also be a great way to improve the look and feel of your home. However, before you start installing carpet on your stairs, you need to know how much carpet you will need. In this article, we will guide you on how to calculate carpet for stairs in 2023.

Step 1: Measure the Stairs

The first step in calculating carpet for stairs is to measure each step and riser. Start by measuring the width of the tread, which is the part of the step that you step on. Then, measure the length of the tread, which is the distance from the back of the tread to the front of the nosing. Finally, measure the height of the riser, which is the vertical height between each step.

Pro Tip:

To ensure accuracy, measure each step and riser twice, and then take the average of the two measurements.

Step 2: Calculate the Total Area

Once you have measured each step and riser, you need to calculate the total area of your stairs. To do this, multiply the width of the tread by the length of the tread. Then, add the area of the riser by multiplying the height of the riser by the width of the tread.

Pro Tip:

If you have an irregularly shaped step, break it down into smaller sections and calculate the area of each section separately.

Step 3: Determine the Amount of Carpet Needed

Now that you have calculated the total area of your stairs, you can determine the amount of carpet needed. To do this, you need to know the width of the carpet roll you plan to use. Divide the total area of your stairs by the width of the carpet roll. This will give you the number of linear feet of carpet you need.

Pro Tip:

It’s always a good idea to add an extra 10% to your total linear feet to ensure that you have enough carpet for any mistakes or waste.

Step 4: Choose the Right Carpet

When choosing carpet for your stairs, it’s essential to consider the durability and safety of the carpet. Look for carpets with a high-density rating and a low pile height. This will ensure that your carpet is strong enough to withstand heavy foot traffic and prevent slips and falls.

Pro Tip:

Consider choosing a carpet with a pattern or texture to help disguise any wear and tear.

Step 5: Hire a Professional

While it’s possible to install carpet on your stairs on your own, it can be a difficult and time-consuming task. Consider hiring a professional to ensure that your carpet is installed correctly and safely.

Pro Tip:

Ask for references and check online reviews before hiring a professional.


Calculating carpet for stairs can be a complex process, but it is essential to ensure that you have the right amount of carpet for your project. By following these steps and tips, you can calculate carpet for stairs in 2023 and create a beautiful and safe staircase in your home.
