Why are large candy bars called king sized?

King-size candy bars are not named after Elvis Presley, but rather because they are larger than the standard-sized bars. The term "king-size" is used to denote a larger size, usually double the size of the original product. In the case of candy bars, the king-size bar is typically twice the size of the regular bar. The term "king-size" has been used in marketing for many years to indicate a larger size, and is not specifically associated with Elvis Presley.
