Most carpet retailers sell in 12-foot-wide rolls and quote prices per square yard. That works for whole-room installs, but it leaves stair runners, hallway rugs, and small-room projects with awkward overage and pricing. Carpet by the foot changes the equation — you buy the exact linear footage of a 12-foot roll, paying only for what you need rather than full square yardage. The category has grown from a contractor secret to a legitimate consumer option through online retailers and local mill outlets.
How Carpet By the Foot Pricing Works
Carpet manufacturers produce rolls 12 feet wide (occasionally 13.5 or 15 feet) and 100 to 150 linear feet long. Standard retail sells these in square-yard increments (1 square yard equals 9 square feet at 12-foot width, equivalent to 0.75 linear feet of roll). Carpet by the foot lets you buy in 1-foot increments along the roll’s length, getting a piece that is 12 feet wide by however many feet long you need.
For a stair runner only 27 inches wide, that means buying a full 12-foot-wide piece and cutting your runner from it. The waste pieces become bound area rugs, dog beds, or just go in the trash. Even with waste, the math often beats buying a custom-cut runner at retail.
When Buying by the Foot Saves Money
Three scenarios deliver real savings:
- Stair runners 14 to 22 feet long — saves 40 to 60 percent versus pre-cut runners
- Hallway carpets in 36 to 60-inch widths — bound edges make a custom runner cheaper than commercial pre-made
- Closet and small bedroom installations under 60 square feet — avoids the 1-yard order minimum at most retailers
For whole-room installations over 200 square feet, traditional square-yard pricing usually wins because installers buy in volume and pass labor efficiencies down.
Where to Buy
Five sources dominate the market:
- Mill outlets — Shaw, Mohawk, and Engineered Floors run direct outlets selling remnants and by-the-foot
- Online retailers — Carpet One, ACWG, and Sisalcarpet.com all offer by-the-foot online ordering
- Independent flooring stores — most local stores will cut from a roll if you ask and pay a small handling fee
- Big-box stores — Home Depot and Lowe’s offer limited cut-by-the-foot service on display rolls
- Auction and remnant houses — local estate sales and warehouse clearouts sometimes carry premium goods at 30 to 60 percent off
Online retailers typically offer the broadest selection but charge $40 to $150 for shipping due to roll weight and dimensions.
Carpet Types Sold By the Foot
Not every product is available in cut-to-length quantities. Common by-the-foot offerings include:
- Berber and loop pile — high stair-runner demand makes these widely available
- Sisal and natural-fiber carpet — ideal for runners and area rugs
- Wool berber — premium runner material at $8 to $15 per linear foot of 12-foot width
- Polyester frieze and shag — limited availability, mostly through mill outlets
- Patterned and printed carpet — variable; check stock with each retailer
Avoid plush nylon for stair runners — the pile mats quickly under traffic and shows wear faster than berber or loop construction.
Pricing Examples
Real-world 2026 pricing:
- Builder-grade nylon berber: $8 to $14 per linear foot of 12-foot width ($0.67 to $1.17 per sq ft)
- Mid-range wool blend loop: $24 to $42 per linear foot ($2.00 to $3.50 per sq ft)
- Premium wool sisal-style: $48 to $84 per linear foot ($4.00 to $7.00 per sq ft)
- Patterned indoor-outdoor: $18 to $30 per linear foot ($1.50 to $2.50 per sq ft)
- Edge binding service: $1.50 to $3.50 per linear foot of cut edge
A 16-foot stair runner in mid-range wool blend with bound long edges totals roughly $580 to $750 before installation, compared to $900 to $1,400 for a custom pre-made runner of similar quality.
Stair Runner Math
Calculate runner length using this formula: count the number of treads, multiply by tread depth (typically 10 to 11 inches), add riser height (7 to 8 inches) per step, then add 12 to 18 inches for the top and bottom transitions. A 13-stair staircase typically needs 16 to 18 linear feet of runner material.
For width, choose between 27, 32, and 36 inches depending on stair tread width. Leave 4 to 6 inches of exposed wood on each side. Order an extra 2 to 3 linear feet of carpet beyond the calculated length to allow for pattern matching and trim cuts.
Edge Binding Options
Cut carpet edges fray without finishing. Three binding options handle the problem:
- Cotton or polyester tape binding — most common, $1.50 to $3.00 per linear foot
- Serged edges — looped thread overcast, $2.50 to $5.00 per linear foot, premium look
- Leather or fabric border — designer option, $5.00 to $12.00 per linear foot
For stair runners, serged edges photograph best and resist fraying for the longest period. Most binding services turn around orders in three to five business days.
Installation Tips
DIY installation works well for small projects. Tools needed: knee kicker, carpet knife with fresh hook blade, tackless strip (already on stair edges in most cases), staple gun with 9/16-inch staples, and a stair tool or putty knife.
For stair runners, install tackless strips at the back of each tread and the bottom of each riser. Center the runner side-to-side before stapling. Work top-down, pulling the runner taut over each tread and stapling along the riser-tread joint. Hand-tack the edges every 4 to 6 inches.
When Custom Beats By the Foot
Pre-made runners with finished edges and matching transitions still make sense for high-end installations where bound edges in matching trim are mandatory. For most homeowners on a budget, carpet by the foot offers the freedom to choose any carpet style at any retailer and customize it for the exact application — without paying the premium of made-to-order runner products.
