【How-to】What size bed does a 48 x 72 blanket fit

If you’re dressing a twin bed, 51 by 60 inches should do the trick. A full/queen will need 68 by 80 inches, and go for a 88 by 104 inch spread for a king. For couch-blanket shoppers, the same principle applies. If your sofa is on the smaller side, definitely opt for the full-sized blanket, and work up from there.
