Carpeting adds value to the home and when placed in the right rooms, makes the room warmer, both literally and figuratively. Once you answer the questions above, you can determine how much carpet you need for your carpet or stair project.

Afterwards, when you’re ready to install or replace your carpet, ImproveNet can connect you with a local carpet contractor.

Types of Carpet

With any new carpet project, you first have to determine what kind of carpeting you want. There are a wide variety of carpet types to choose from, both in style and fabric type. In terms of style, they can be woven, needlefelt, knotted, or tufted—just to name a few. Each has their own strengths and weaknesses in terms of feel, durability and look.

Carpets also vary in price when mixed with the different fabrics, ranging from nylon, polypropylene, wool or wool-blends, polyester and acrylic. The best way to know which suits your needs is to feel them and talk to a local carpeting expert.

Carpet Measurements

Once you decide what kind of carpet you want, it’s time to figure out how much you need for your home. The goal when laying carpet is to not have seams, or as few as possible. To determine a floor's square footage, measure and draw the room. Measure the width of the room at its widest point. Measure the length of the room at its longest stretch. Then, multiply those two longest points by each other to determine the square footage of the room.

Carpeting is usually sold by square yards, but some dealers give a square foot price. Most come in rolls of 9-, 12- or 15-feet wide. If there has to be a seam, place it away from the doorway and somewhere where people won’t be walking over it often.

For stairs, measure one stair tread (the horizontal part) from one side to the other side of the rail (or wall) and then round it off to the nearest foot. Then, measure the stair from the bottom to the top of the tread (the vertical part) and round off to the nearest foot. Multiply these two together to determine the area of the stair. Add three inches if you plan to use carpet padding. Count all the stairs and multiply that number by the area to determine how many square feet of carpet you’ll need.

Find A Carpet Contractor

Carpet installation is no easy task. Once you determine how much carpet you need, connect with at least three local carpet contractors to get the best bid for your project.
