dimension -
the magnitude of something in a particular direction (especially length or width or height)
magnitude the property of relative size or extent (whether large or small); "they tried to predict the magnitude of the explosion"; "about the magnitude of a small pea"
length a section of something that is long and narrow; "a length of timber"; "a length of tubing"
width,
breadth the extent of something from side to side
tallness,
height the property of being taller than average stature
third dimension the dimension whereby a solid object differs from a two-dimensional drawing of it
dimension -
one of three Cartesian coordinates that determine a position in space
cartesian coordinate one of the coordinates in a system of coordinates that locates a point on a plane or in space by its distance from two lines or three planes respectively; the two lines or the intersections of the three planes are the coordinate axes
dimension -
a construct whereby objects or individuals can be distinguished; "self-confidence is not an endearing property"
dimension -
An alternative universe or plane of existence.
Verb
dimension -
To mark, cut or shape something to specified dimensions.
Wikipedia
The dimension of a space or object is informally defined as the minimum number of coordinates needed to specify each point within it. Thus a line has a dimension of one because only one coordinate is needed to specify a point on it. A surface such as a plane or the surface of a cylinder or sphere has a dimension of two because two coordinates are needed to specify a point on it (for example, to locate a point on the surface of a sphere you need both its latitude and its longitude).
