Runner rugs typically measure between 2 and 3 feet wide and 4 to 12 feet in length. That makes them perfect not only for hallways but any place you need a splash of color and a little cushion, even when you don't have a lot of space. Runners are great in entryways or mudrooms, in front of a bathroom vanity, or on either side of a bed for a soft landing when you get up in the morning.
