Stair carpet ideas: full carpet on stairs or a runner, and how to decide
The first stair carpet idea is a decision, not a pattern: carpet the whole stair wall to wall, or lay a runner and show the wood at each side. Full carpet is the quiet, safe choice for a closed stair, a stair with no wood worth showing, or a house that is carpeted upstairs; a runner, 27 to 36 inches wide with 3 to 6 inches of tread showing each side, is the choice for a wood or painted stair, an open or feature stair, and any client who wants the stair to look designed. Both take a dense low-profile carpet on a firm 1/4 to 3/8 inch pad.
This guide is for the designer deciding how a stair will be finished and the junior pricing the two routes against each other: what each asks of the stair, the yardage and labor difference, when each is the wrong answer, the ideas that follow, and the landing.
Full carpet on stairs: what it gives and what it asks
Wall-to-wall on a stair covers the treads and risers edge to edge, cut and tucked at the skirt board or wrapped around an open edge. It is the quietest stair, since every tread is padded; the safest for children and older clients, since there is no edge to catch; and the most forgiving of a stair not worth showing. It asks for careful cutting on an open stair, where the carpet wraps each tread end and the balusters, and for a carpet made for the job: a dense loop, a tight cut pile or a woven, in nylon or wool, pile 1/2 inch or under. Plush and frieze fail at the nosing. The best carpet for stairs guide ranks the fibers and constructions.
A stair runner: what it gives and what it asks
A runner leaves the stair visible, so it asks for finished treads and risers in wood, paint or stone, in good enough condition at the edges to photograph. In return the runner is the design piece: a pattern, a stripe, a border, brass rods if the house suits them. It walks the family up the center, so wear is where the carpet is and the wood survives, and it can be changed in ten years without touching the stair. It can be cut from almost any broadloom in the library, roughly 3,500 styles against the 59 made specifically as runners; see the custom runner rugs guide for the cut-and-bound route.
Carpet on stairs vs runner, side by side
| Factor | Full carpet on stairs | Stair runner |
|---|---|---|
| Stair underneath | Any; hides plywood, paint, damage | Must be finished wood, paint or stone worth seeing |
| Material for a 13-step straight stair, 36 in wide | About 8 to 9 sq yd of broadloom from a 12 ft roll, with waste | About 24 ft of 27 in runner, or 7 sq yd of broadloom cut to width and bound |
| Labor | More cutting and tucking on an open stair; less on a closed stair | Centering, binding and stapling; more skilled, less cutting |
| Sound | Quietest | Quiet on the runner, wood sound at the edges |
| Pattern choice | Small-scale or solid; large patterns waste yardage | Any pattern that runs up the stair; borders, stripes, herringbone |
| Replacement | Whole stair, with the stair stripped | Runner only, in a day |
Both routes use the same pad: 1/4 to 3/8 inch dense, cut tread by tread, never the room pad; see the carpet pad for stairs guide.
When a runner is the wrong answer
Three cases. A closed stair with painted plywood treads: the reveal shows plywood, and a runner costs more than carpeting it edge to edge. A stair narrower than 32 inches: a 27-inch runner leaves 2 1/2 inches of wood each side, which reads as a mistake. And a stair for a client with mobility concerns, where the firmest, most continuous surface is the point. In each case full carpet is the better spec.
When full carpet is the wrong answer
A hardwood stair in a house with hardwood floors, where carpeting edge to edge hides the millwork the client paid for. An open-string stair with turned balusters, where wrapping carpet around every tread end never looks clean. Any stair the client wants as the entry's feature. And a stair connecting a hardwood hall to a carpeted upper floor, where a runner carries the hall up and the carpet takes over at the landing.
Stair carpet ideas once the route is chosen
For full carpet: a wool loop in a mid-tone heather, which hides nosing wear and photographs as texture; a small-scale woven check or pin dot that needs no matching step to step; a cut-and-loop tone-on-tone that reads as a stripe up the flight; or the upper hall's carpet run down the stair so the two floors read as one. For a runner: a wide stripe in a wool flatweave on a painted stair; a herringbone with a dark border on a wood stair, covered in the herringbone and striped stair runner guide; a Wilton with a woven border and brass rods in a traditional house; a sisal with a cotton border in a coastal house, with the caveat that sisal is slick; or a solid wool loop with a contrast binding on a modern stair. The patterned stair runner guide has eight more with the catch in each.
Stair and landing carpet ideas
Full carpet continues across a landing with the pile direction kept consistent. A runner stops at the landing, is bound, and either a landing piece is laid with the pattern turned to run the landing's length, or the landing is left bare where it is a room of its own. If the upper floor is carpeted, the runner ends at the landing and the carpet begins there with a sewn or metal transition. Send us the landing size and the upper-floor finish with the step count and we draw the yardage for either route.
Questions designers ask
What type of carpet is best for stairs?
A dense, low-profile carpet in wool or nylon: a loop, a tight cut pile or a woven Wilton, pile 1/2 inch or under, on a firm 1/4 to 3/8 inch pad. Wool is naturally flame resistant and resilient at the nosing; solution-dyed nylon is the practical alternative for a house with dogs. Avoid plush, frieze and polyester cut pile.
What is the 27 rule for stairs?
27 inches is the standard runner width, chosen because it leaves 4 1/2 inches of tread showing each side on a 36-inch stair, the proportion most eyes read as right. On a 42-inch stair, 32 inches does the same job; on a 48-inch stair, 36 inches.
What should be done with a stair runner on a landing?
Cut and bind the runner at the landing, lay a landing piece with the pattern turned to run the landing's length, and restart the runner centered on the upper flight. A herringbone or a solid takes the turn cleanly; a stripe usually looks better with a plain landing piece. If the upper floor is carpeted, end the runner at the landing.
Should the stair carpet be lighter or darker than the floor?
A half step to a full step darker than the floor it meets, in a mid-tone. Darker anchors the stair and hides nosing wear; lighter than a dark wood floor shows soil and reads as a break between the levels. Match the hall carpet exactly if the stair carries the same carpet up.
