The size of a commercially made receiving blanket varies by manufacturer with some measuring 30 by 40 inches and others measuring 30 by 34 inches. Some homemade receiving blankets vary in range from 32 by 32 inches to 36 by 36 inches.
Makers pf homemade blankets claim that store-bought receiving blankets are not always big enough for swaddling. Receiving blankets are often used for swaddling newborn infants in order to help them feel more secure. Some styles are made with hoods in one corner to help keep baby's head warm while swaddled. Swaddling is thought to be comforting to infants and is believed to help keep them calm. Swaddling past the age of one month is not recommended as it may impede physical development.
