Materials and Tools

First thing first. Start by collecting the tools and materials to be in a position to execute the process of cutting carpet for your stairs.

1. Measuring tape

Accurate measurements are crucial to ensure that you have enough carpet for your staircase. Use a measuring tape to measure the length and width of each stair and calculate the amount of carpet needed.

2. Carpet knife

A sharp carpet knife is the most essential tool for cutting the carpet to fit each stair. Make sure the blade is sharp so that it cuts through the carpet cleanly and evenly.

3. Straight edge

Use a straight edge, such as a ruler or a carpenter’s square, to ensure straight cuts and to guide the carpet knife along the edge of each stair.

4. Staple gun and staples

A staple gun is used to attach the carpet to the stairs. Use heavy-duty staples to ensure that the carpet is securely fastened.

5. Seam roller

A seam roller is a small tool that is used to press the carpet into the corners and edges of the stairs, ensuring a smooth and seamless finish.

6. Knee kicker

A knee kicker is a tool used to stretch the carpet into place, ensuring that it fits snugly over the stairs and stays in place.

5. Carpet pad

A carpet pad provides extra cushioning and helps to prolong the life of the carpet. Measure and cut the carpet pad to fit each stair, then staple it in place.


The next thing you need to do is to prepare.

Failure to prepare is the plan to mess along with your task. Preparation ranges from the tool, material, and area you are working on. Make sure all your tools are in good condition.  Knife sharpened or with a new blade.

Clear the area

Begin by removing any furniture or objects from the stairs or surrounding area. This will make it easier to move around and ensure that nothing gets in the way of the cutting process.

Remove any old carpet or padding

If there is any old carpet or padding on the stairs, it will need to be removed before cutting the new carpet. Use pliers or a staple remover to remove any staples, tacks, or nails that may be left behind.

Clean the stairs

Thoroughly clean the stairs and surrounding area to remove any dirt, grits, or adhesive residue. A clean surface will ensure that the carpet adheres properly to the stairs.

Measure the stairs

Use a measuring tape to measure the length and width of each stair. Be sure to account for any angles or curves in your measurements.

Calculate the amount of carpet needed

Add up the total length and width of all the stairs to calculate the carpet needed. It’s always a good idea to add a little extra to account for mistakes or unforeseen circumstances.

1. Measure and mark the carpet

Use a measuring tape to measure the length and width of each stair, and transfer these measurements onto the back of the carpet using a marker or chalk. Double-check your measurements to ensure accuracy.

2. Cut the carpet to size

 Use a carpet knife to cut the carpet to the appropriate size for each stair, following the marks you made in the previous step. Use a straight edge, such as a ruler, to ensure straight cuts.

3. Cut the carpet for tricky angles or curves

 For stairs with angles or curves, it’s important to take extra care when cutting the carpet. Make small, straight cuts around the angle or curve, cutting away excess carpet gradually until the carpet fits smoothly.

How to lay carpet on stairs

3. Tuck the carpet into the corners

For stairs with corners, use a stair tool or a putty knife to tuck the carpet into the corners securely. Make sure there are no gaps or bumps in the corners.

4. Trim excess carpet

Once the carpet is secured in place, use a carpet knife to trim any excess carpet around the edges of each stair. Make sure the cuts are straight and clean.

Maintaining the carpet on your stairs is essential to ensure its long-lasting durability and cleanliness. Here are some tips to help you maintain your carpet on the stairs:

  1. Vacuum regularly: Vacuum the stairs regularly to remove any dirt, dust, or debris that may accumulate on the carpet. This will prevent the buildup of dirt and extend the life of the carpet.
  2. Clean up spills immediately: Accidents happen, so if a spill occurs on the stairs, clean it up immediately to prevent it from setting into the carpet fibers. Use a clean cloth and a carpet cleaner to blot up the spill and prevent staining.
  3. Use a carpet cleaner: Periodically, use a carpet cleaner to deep clean the stairs and remove any dirt, stains, or odors. Follow the instructions on the carpet cleaner carefully, and make sure to rinse the carpet thoroughly to remove any residue.
  4. Avoid wearing shoes on the stairs: Shoes can track dirt and debris onto the carpet, causing it to wear out more quickly. Encourage family members and guests to remove their shoes before walking on the stairs.


Does stair carpet need to be one piece?

No, stair carpet does not necessarily need to be one piece. In fact, it is common for stair carpet to be installed as individual treads rather than one continuous piece. This is because stairs can have varying sizes and shapes, and it may be difficult to find a single piece of carpet that fits perfectly over each stair.

Instead, the carpet is typically cut to size for each stair tread and installed individually, with seams between each tread. This allows for a more custom fit and ensures that each stair is covered properly.

Can you put carpet squares on steps?

Yes, it is possible to install carpet squares, also known as carpet tiles, on steps. Carpet squares are an alternative to traditional carpet rolls and come in small squares or rectangles that can be easily installed with adhesive.

One advantage of using carpet squares on steps is that they are more customizable than traditional carpet.

You can mix and match different colors and patterns to create a unique look for your stairs. Additionally, carpet squares are often more durable than traditional carpets, which can make them a good choice for high-traffic areas like stairs.
