Runners are commonly made from synthetic fibers such as polyester and polypropylene, while some options use natural-fiber blends (for example, jute blended with cotton).
Stair runners are most often low pile (under 0.5") for a low profile; some styles offer medium pile (about 0.5"–1") when a plusher feel is preferred.
Some runners include non-slip backings (rubber or latex/TPR), while others have no backing and recommend using a separate rug pad to prevent slipping and keep the runner in place.
Runners are commonly offered in lengths from about 72 inches up to 144 inches, with typical widths around 24 to 32 inches—covering most hallway and stair needs.
Many listings recommend pairing a runner with a rug pad for added comfort and to extend the rug's life, while some runners include built-in non-slip or latex/TPR backings that may reduce the need for a separate pad.
