queen-size

terms like this give new meaning to the roles of kings and queens as "rulers." The term is irreplaceable because of its specific descriptions of beds and bed linen (where the use of "single," "double," "queen," and "king" is standard) and its euphemistic use for such items as queen-size pantyhose. However, it undergirds the female-as-lesser/smaller perspective and if you simply mean "very large," you might consider one of the many synonyms of huge. See also king-size.
