A Simple Guide To Measuring Carpet For Your Stairs

A simple wooden staircase may be given some visual interest by adding carpeting. It’s important to measure the steps so you know precisely how much carpet is required to cover them before you start looking at carpet swatches. Are you aware of the proper measurements for carpet runners on your stairs? Even on curved stairs, it's simpler than you may imagine.

Comparatively different procedures are needed when measuring stairs than when measuring a hall. Stair tread runners can range in width from 22 to 36 inches and are usually available by the running foot or yard. You must take measurements of the stair tread depth and riser height in order to determine the length of the staircase for a runner. The threshold, the passageway, the linear steps, and the curved steps should all be measured separately and recorded.

Stairs should be within acceptable size ranges unless your property was designed specifically for you. Remember that various regions have different building codes, so you can come across sizes that are a little bit different from those listed here. Measure with care, of course!

There’s nothing to worry about if you don't know how to estimate stairs for carpeting or how to add up all the dimensions so you can get the appropriate amount of carpet.

As luck would have it, Direct Carpet flooring specialists have put up a straightforward tutorial on how to measure stairs for carpet. Here is a simple guide in this article to help you calculate the carpet for your staircase.

What Really Is Required For Measuring The Stairs for Carpet?

We suggest that you obtain a pencil, a notepad, and a hard metal tape measure. Graph paper is frequently used since it may help you see the area better.

Be careful to always measure from the broadest points, accounting for any doors, if your room includes alcoves or a bay window.

A base design, specific stair dimensions, and a hallway layout should all be included in your final design if you strictly adhere to our helpful step-by-step guide on how to measure stairs for carpet.

This will give you everything you need to purchase a carpet for your stairs. Let’s start measuring, so grab a ruler or tape measure.

Measurement Of A Room for Carpet:

We suggest drawing the room first, outlining all of the walls, and indicating where the doors should be. Take the room's longest and widest measurements while taking note of any bay windows or door recesses.

If the room includes alcoves, measure their width and depth since you could need this information if you need to combine the rooms. As a general guideline, you can calculate the total length and breadth needed if you measure each wall in your room.

Measuring Your Hall for Carpet:

It's time to take measurements for a carpeted hallway! Create a floor plan for your hallway, then measure it just as you would a room, taking care to account for any doors, alcoves, and dropbacks.

Take a few measures from wall to wall, keeping in mind that not all walls are parallel.

Once all the measurements have been obtained, mark the location of the stairs' entrance to the hallway on your floor plan with an arrow. For pile direction, this is crucial.

A Stair Landing Measurement for Carpet:

Lay out the landing and draw the contour of the landing by standing at the top step, just like you would while measuring the hallway with the exception that you must take into consideration the riser/lip of the top step.

Always draw an 'X' or identify the direction of the steps where the landing meets them.

The top riser of the stairs is always included in the landing carpet piece, therefore measure over the top step as indicated by the arrow in the image below.

It’s crucial to collect as many measurements as you can since you might be able to use the waste for your steps. When measuring the overall width and length, keep in mind to provide space for door recesses.

How To Calculate A Staircase With Turns for Carpet

Additionally, some staircases contain winders, which are curved stairs. These must be gauged separately and a little bit differently than straight stairs.

You must take a measurement at the winder's widest point to determine its width. By doing this, you will guarantee that you have enough carpet to completely cover the step even if your tape measure won't be precisely parallel to it.

Apply this procedure to every winder. Similarly, the deepest edge of the step should be at a 90-degree angle to your tape measure when measuring the tread and riser.

How Much Carpet Square Footage Should There Be On The Stairs?

Stage 1:

Simply measure the height and depth of one step in inches and put the figures together to determine the square footage needed for carpet on stairs. Add another inch to wrap around the nose.

Stage 2:

Multiply it by how many stairs there are.

Stage 3:

To determine the number of feet, divide that number by 12 and round up.

Stage 4:

Round your measurement of the stairway's width up to the nearest foot. To get the square footage, multiply this amount by the figure that was previously determined in Step 3.

Regardless of how much carpet you estimate you'll need, you must always purchase a small amount more to account for any abnormalities or installation errors.


Once you master the core arithmetic and measurement methods, trying to measure stairs for carpets is an easy operation. You’ll be one bit closer to the carpet installation procedure after you've determined your staircase's final measurements. Go to the ordering page on Direct Carpet after selecting your rug and border color to place your purchase. You must also choose whether you will perform the installation yourself as a do-it-yourself job or hire an installer.
