- a property of space; extension in a given direction: A straight line has one dimension, a parallelogram has two dimensions, and a parallelepiped has three dimensions.
- the generalization of this property to spaces with curvilinear extension, as the surface of a sphere.
- the generalization of this property to vector spaces and to Hilbert space.
- the generalization of this property to fractals, which can have dimensions that are noninteger real numbers.
- extension in time: Space-time has three dimensions of space and one of time.
- measurement in length, width, and thickness.
- scope; importance: the dimensions of a problem.
- a magnitude that, independently or in conjunction with other such magnitudes, serves to define the location of an element within a given set, as of a point on a line, an object in a space, or an event in space-time.
- the number of elements in a finite basis of a given vector space.

Scientific definitions for dimension
- Any one of the three physical or spatial properties of length, area, and volume. In geometry, a point is said to have zero dimension; a figure having only length, such as a line, has one dimension; a plane or surface, two dimensions; and a figure having volume, three dimensions. The fourth dimension is often said to be time, as in the theory of General Relativity. Higher dimensions can be dealt with mathematically but cannot be represented visually.
- The measurement of a length, width, or thickness.
