Using a flexible measuring tape, one can measure a king-size bedspread by measuring its width and height, which is how manufacturers list bedspread specifications. Typical bedspreads for a standard king-size mattress are 102 inches by 86 to 88 inches.
Dimensions for a king-size bed depend on the type of king-size bed as well as the type of bedspread being measured. While standard or eastern king-size beds measure at 76 to 78 by 80 inches, California or western king-size beds measure narrower but longer at 72 by 84 inches.
Coverlets, duvets, quilts and comforters are popular types of bedspreads that all vary in width and length depending on manufacturer specifications.
