Carpet remnants range in size since they come from the extra sheets from a roll of carpeting. The sources of these carpet scraps usually dictate the dimensions. Carpet remnants vary in size depending on where they come from. It is common to think that carpet remnants are just tiny portions of carpet, but they come in various sizes. Some carpet scraps can come in small parts as small as 3ft or as big as 12ft or more. Carpet dealers and retailers are sometimes left with unusual sizes of carpet scraps which are usually smaller than the usual carpet sizes and cannot be sold at a full price. When the size of the carpet to be installed was overestimated, some parts of the carpet had to be snipped off, resulting in smaller size carpet scraps. Carpet retailers commonly sell the larger size scraps at a lower price, so they will not lose too much money. Some remnants are offered free if you buy a roll of carpet.
