Broadloom Carpet: How Wall-to-Wall Carpet Is Made, Sold, and Installed

Broadloom carpet covers more residential and commercial floor area than any other soft floor covering in North America, yet few buyers understand how it is made or priced. The term describes carpet woven on a wide loom, and in everyday use it means tufted, wall-to-wall carpet sold on rolls and installed as one continuous surface. Knowing how the product is manufactured, measured, and laid helps homeowners compare quotes, estimate material, and avoid costly mistakes at the retail counter. The sections below cover loom construction, roll sizes, square yard pricing, pile types, installation sequences, and the process of converting roll goods into area rugs.

How Broadloom Carpet Is Made

Manufacturing starts with yarn, not with the loom. Most broadloom sold today is tufted: a machine punches thousands of yarn loops through a woven or nonwoven primary backing, usually polypropylene, to form the pile. A coating of latex and a secondary backing fabric are then applied to the back of the carpet, locking the tufts in place and giving the roll dimensional stability. Only a small share of production uses true weaving, where face yarn and backing yarn are interlaced on a loom the way fabric is made.

From Fiber to Finished Roll

Fiber choice happens first, and it drives both price and performance.

• Nylon: the most common face fiber in residential carpet; resists crushing and recovers well from traffic.
• Polyester: a softer hand and lower cost with good color clarity, but less resilience in busy areas.
• Polypropylene (olefin): stain- and moisture-resistant, frequently used in basements, sunrooms, and commercial loop piles.
• Wool: a natural fiber with high durability and inherent flame resistance at a premium price.
• Blends: wool-nylon and other combinations balance cost with performance.

Tufted and Woven Construction

Tufting machines run fast. A modern tufter inserts more than 1,000 stitches per minute and produces a residential-quality roll in a fraction of the time weaving requires, which is the main reason tufted broadloom dominates the market. Woven carpets such as Wilton and Axminster are built on looms that interlace pile yarns with warp and weft yarns, making them denser, slower to produce, and noticeably more expensive per square yard.

Filament Yarn vs. Staple Yarn

The yarn itself comes in two forms. Filament yarn is a continuous strand, so it does not shed fiber fragments and holds up better under heavy traffic. Staple yarn is spun from short fibers, which gives a softer, more textured hand but can shed lint during the first months and wears faster in high-use areas.

How Broadloom Is Sold

Broadloom is priced and sold in units that surprise first-time buyers. The carpet comes off the line in rolls of a standard width, and the retailer charges by area rather than by the roll. Two conventions dominate the transaction: roll width and the square yard.

Roll Widths and Roll Lengths

The standard roll width in North America is 12 feet. Manufacturers also produce 13-foot-6-inch and 15-foot rolls, and specialty widths exist for specific products. Rolls run approximately 150 feet in length, so a 12-foot-wide roll contains about 1,800 square feet of carpet, or 200 square yards. Wider rolls mean fewer seams in a large room: a 20-foot-wide great room needs a seam with a 12-foot roll but can be covered in one piece with a 15-foot roll.

Square Yards vs. Square Feet

Pricing units vary by region and market. Hard surface flooring such as hardwood, tile, and vinyl plank is quoted per square foot, and the carpet industry has largely followed that practice. Canada, which is officially metric, still prices broadloom in imperial units because the flooring trade there relies on them. One yard equals three feet, so one square yard, measuring 3 feet by 3 feet, contains nine square feet. A room 12 feet by 15 feet covers 180 square feet, or exactly 20 square yards, so $4 per square foot and $36 per square yard describe the same $720 order. Knowing both units prevents math errors at the counter.

Why the 12-Foot Roll Matters

Roll width dictates how a room is laid out. A room 14 feet wide cannot be covered with a single 12-foot piece, so the installer either seams in a 2-foot fill strip or orders a wider roll. Seams add labor and can show as visible joints in low-pile styles, so room dimensions relative to roll width directly affect the final price. Estimates should also include installation waste of 5 to 10 percent for cuts, seams, and pattern matching, plus the cost of cushion and labor. Specifiers comparing materials can consult the broadloom carpet product guide at BuildingGreen, which documents recycled-content options, certification programs, and indoor air quality considerations for wall-to-wall carpet.

Types of Broadloom Carpet

Broadloom is categorized by pile construction first, then by fiber and style. The two broad families are cut pile and loop pile, with woven constructions occupying a premium niche.

Cut Pile Styles

• Plush and saxony: dense upright cut tufts with a smooth, formal appearance; shows footprints and vacuum marks, best in low-traffic rooms such as bedrooms.
• Textured cut pile: twisted yarns cut at varying heights for a casual, heathered look that hides footprints.
• Frieze: tightly twisted, low cut pile with a curly, nubby texture that hides traffic and wear; a common choice for family rooms and stairs.

Loop Pile Styles

• Berber: looped yarn, often flecked or speckled, in a loose, textured surface that resists crushing and shows little traffic wear.
• Level loop: uniform loops in a smooth, dense surface; common in commercial installations and basements.
• Multi-level loop: loops at two or more heights that form patterns, used for geometric designs.

Woven and Specialty Constructions

True woven broadloom includes Wilton and Axminster, produced on power looms that interlace pile with a structured backing. These carpets are denser and more durable per ounce of face fiber, which is why they appear in hotels, theaters, and high-end residences. Needlefelt and carpet tile compete with broadloom in contract markets, and tufted broadloom itself spans a wide performance range depending on face weight.

How Broadloom Is Installed

Wall-to-wall carpet is installed with the stretch-in method in most homes. The carpet is laid over cushion, hooked to tackless strips around the perimeter, and stretched taut so it stays flat without glue.

Cushion and Subfloor Preparation

The subfloor must be clean, dry, and flat before anything else happens. Installers remove old carpet and padding, pull staples and nails, and fill depressions in plywood subfloors. Concrete slabs get a moisture check, because trapped vapor degrades cushion and backing over time. Residential cushion typically runs 6 to 8 pounds density and 7/16 to 1/2 inch thick; commercial jobs use denser, thinner padding to carry rolling loads.

The Stretch-In Sequence

1. Install tackless strips around the room perimeter about 1/2 inch from the wall, with the pins angled toward the wall.
2. Lay cushion over the subfloor, stapled or glued, and trim it to the strip line.
3. Cut the broadloom with several inches of overlap on each wall.
4. Join pieces at seams with hot-melt seaming tape under a seaming iron, then roll the seam flat.
5. Hook the carpet onto the tackless strips with a knee kicker along the walls.
6. Stretch the field with a power stretcher from wall to wall to remove wrinkles.
7. Trim the edges with a carpet knife and tuck them into the gap between strip and wall.

Seaming and Pattern Matching

Seams are the weak point of any wall-to-wall installation. When two pieces meet, the installer must match pile direction and, for patterned carpet, align the pattern repeat across the joint. Pattern matching adds waste: a carpet with a 36-inch repeat may need an extra 10 percent of material so the design lines up at every seam. Poor seams show as visible lines, especially in low-pile styles and under side light.

Turning Broadloom Into Area Rugs

A homeowner with leftover broadloom, or a retailer with remnant stock, can convert roll goods into area rugs. The process is simple in concept: cut the carpet to a rectangle, finish the cut edges so they do not unravel, and optionally add a border or backing.

Cutting and Edge Finishing

The cut edge of tufted carpet exposes backing and yarn ends that fray without treatment. Two finishing methods dominate the remnant market.

• Serging: a machine sews a tight overlock stitch around all four edges; the most common finish for custom rugs and remnants.
• Binding: a fabric tape, usually cotton or polyester, folded over the raw edge and sewn down; a good choice for crisp, straight edges.

Adding Backing and Borders

Rugs cut from broadloom keep the latex-and-scrim backing of the original roll, which works well on hard floors. For placement over existing carpet, a non-slip pad or a separate slip-resistant backing prevents movement. Decorative borders can be sewn on for a more finished look, and custom shapes are possible, though rectangles and squares are easiest to edge neatly. Cutting a 12-foot roll down to a 9-foot by 12-foot rug wastes nothing if the remainder finds a use elsewhere.

Pros and Cons of Broadloom Carpet

Broadloom stays a default choice in some rooms and a debated one in others. The trade-offs show up in comfort, maintenance, and replacement cost.

What Broadloom Does Well

• Comfort and acoustics: soft underfoot, absorbs sound, and insulates floors in cold climates.
• Coverage economics: one 12-foot roll covers large areas with fewer seams than tile or plank at comparable labor.
• Design flexibility: installed wall to wall, it unifies a room visually and changes the color story without repainting.
• Safety: soft surfaces reduce slip injuries and cushion falls, which is why broadloom stays common in bedrooms and senior housing.

Where Broadloom Falls Short

• Maintenance: vacuuming is routine, but spills and soil require periodic deep cleaning, and stains can become permanent in light colors.
• Wear life: most residential broadloom lasts 5 to 15 years under normal traffic, shorter than hard surface options.
• Allergens: dust mites and allergens accumulate in the pile, and households with asthma often prefer hard floors with washable rugs.
• Replacement cost: removing and hauling old carpet adds to every redo, and wall-to-wall carpet cannot move with you to a new home.
• Indoor air: fresh carpet can off-gas VOCs from latex and dyes; low-emission products certified under programs such as CRI Green Label Plus reduce the concern.
