In the UK a 'Double' is 4' 6" wide.A double bed is either 54 inches wide x 75 inches long or 55 inches wide x 79 inches long.
A twin mattress is 75 inches long and 38 inches wide. This is smaller than a double bed, and is considered a bed for a child. Two adults would not fit on a twin size bed.
Feet are larger than inches.
3.25 feet.
A California King bed is 72 inches wide by 84 inches long. This is 4 inches narrower by 4 inches longer than a standard king size bed.
King size bedding would be much too big for a double bed. A double bed is 2 sizes smaller than a king size and therefore the bedding would be way too big to fit onto the double bed.
