The size of a single blanket can vary depending on the manufacturer and the intended use. However, a standard size for a single blanket is usually around 60 inches x 90 inches. This size is suitable for a twin-sized bed and provides enough coverage to keep you warm and cozy while sleeping.
Single blankets are often marketed as throw or lap blankets and can also be used for layering on a larger bed or for extra warmth while lounging on the couch. The size of a single blanket can also vary based on the type of material, with some materials, such as wool, often available in larger sizes to provide more warmth.
In summary, a standard size for a single blanket is 60 inches x 90 inches, but the size can vary based on the intended use and the type of material. When shopping for a single blanket, check the size and weight specifications to ensure that it will meet your needs.
