King size headboards are not a âone size fits allâ accessory. They do not come in a single standard size. In terms of width, the minimum is 6 feet, 4 inches to accommodate a king-size mattress. A typical width range for a king headboard measures 6 feet, 7 inches to 7 feet. Usually the style determines how wide a headboard can be. The height of a king headboard may range from around 3 1/2 feet to almost 6 feet. How tall a headboard ends up depends on the design and material used. For example, a sleek, contemporary style may be as low as 43 inches. A medium-size leather headboard may measure anywhere from 4 feet, 3 inches to 4 1/2 feet. A height of 5 feet or more is common for a tall wooden sleigh headboard. The bedâs height is another important consideration. Bed frames vary in height, and mattresses can be as thick as 1 1/2 feet or as low as 8 inches.
