The average size of a Turkish rug can vary depending on the style and purpose of the rug. For example, small accent rugs or prayer rugs may be as small as 2' x 3', while larger area rugs can range from 5' x 7' to 8' x 10' or larger. Some Turkish rugs, such as runner rugs, may be long and narrow, measuring anywhere from 2' x 6' to 4' x 12' or more.
