Parameter vs. Perimeter It's very easy to confuse parameter with perimeter . Not only do the two words sound the same, they both connote a boundary or limit. When parameter is used to mean "a boundary or limit," it is usually in its plural form, and often as the object of a preposition such as within or beyond : Let's face it, managing weight loss or maintenance can be trying enough within the parameters of a daily routine. Geoff Kerr, Weight Watchers , November 1991 Though candor sometimes encourages Bruno to "stray beyond the parameters of good taste," his interaction with Lydia is always convincingly portrayed as a loving, tender relationship. Ron Charles, The Washington Post , 8 Feb. 2011 In geometry, perimeter refers to the boundary of a closed plane figure. You might remember calculating perimeters in school. If each side of an equilateral triangle measures 9 feet, then the perimeter of the triangle measures 27 feet. In more general use, perimeter describes an outer stretch, as in "The college president lived in a house on the perimeter of the campus." Parameter originally had a meaning pertaining to mathematics as well. The dictionary defines it as "an arbitrary constant whose value characterizes a member of a system (as a family of curves); also : a quantity (as a mean or variance) that describes a statistical population" as well as "an independent variable used to express the coordinates of a variable point and functions of them." Some twentieth-century usage commentators objected to the use of a scientific-sounding word like parameter in general contexts (as in the examples above), especially to mean "a limit or boundary," theorizing that perimeter must have been what the speaker or writer intended. However, perimeter was not often used in the phrasings that parameter is used in (that is, as the object of within or beyond ) until much later. In fact, a word such as bounds or range or confines often serves as a more appropriate equivalent for parameter than the marginal connotations of perimeter: But a true novel is an extended piece of fiction: Length is clearly one of its parameters . Anthony Burgess, The New York Times Book Review , 5 Feb. 1984 Shields will then subsume that request in the overall City operating budget that he will recommend to the City Council in mid-March, and the Council will make its final decisions on the parameters of the budget, including any tax increases or cuts, by the end of April.
