  • noun A measure of spatial extent, especially width, height, or length.
  • noun Extent or magnitude; scope.
  • noun Aspect; element.
  • noun The least number of independent coordinates required to specify uniquely the points in a space.
  • noun The range of such a coordinate.
  • noun Physics A physical property, such as mass, length, time, or a combination thereof, regarded as a fundamental measure or as one of a set of fundamental measures of a physical quantity.
  • transitive verb To cut or shape to specified dimensions.
  • transitive verb To mark with specified dimensions.

from The Century Dictionary.

  • To measure the dimensions of; proportion.
  • noun Magnitude measured along a diameter; the measure through a body or closed figure along one of its principal axes; length, breadth, or thickness.
  • noun Hence A mode of linear magnitude involved (generally along with others) in the quantity to which it belongs.
  • noun Bulk; size; extent or capacity: commonly in the plural: as, the question is assuming great dimensions.
  • noun That which has extension; matter; especially, the human body and its organs: so often in the plural.

  • noun Measure in a single line, as length, breadth, height, thickness, or circumference; extension; measurement; -- usually, in the plural, measure in length and breadth, or in length, breadth, and thickness; extent; size
  • noun extension that has length but no breadth or thickness; a straight or curved line.
  • noun extension which has length and breadth, but no thickness; a plane or curved surface.
  • noun extension which has length, breadth, and thickness; a solid.
  • noun as imaginary kind of extension, which is assumed to have length, breadth, thickness, and also a fourth imaginary dimension. Space of five or six, or more dimensions is also sometimes assumed in mathematics.
  • noun Extent; reach; scope; importance.
  • noun (Math.) The degree of manifoldness of a quantity
  • noun (Alg.) A literal factor, as numbered in characterizing a term. The term dimensions forms with the cardinal numbers a phrase equivalent to degree with the ordinal; thus, a2b2c is a term of five dimensions, or of the fifth degree.
  • noun (Phys.) The manifoldness with which the fundamental units of time, length, and mass are involved in determining the units of other physical quantities.
  • noun (Carp.) lumber for building, etc., cut to the sizes usually in demand, or to special sizes as ordered.
  • noun stone delivered from the quarry rough, but brought to such sizes as are requisite for cutting to dimensions given.
