Dimensions.com is an ongoing reference database of dimensioned drawings documenting the standard measurements and sizes of the everyday objects and spaces that make up our world. From left to right: a square, a cube and a tesseract. The square is two-dimensional (2D) and bounded by one-dimensional line segments; the cube is three-dimensional (3D) and bounded by two-dimensional squares; the tesseract is four-dimensional (4D) and bounded by three-dimensional cubes.

Understanding the Context

We provide the world’s largest collection of linked research data, accessible via our web platform and time-saving, workflow-based applications. The Dimensions database consists of vast amounts of linked data from various disciplines in a single platform. The meaning of DIMENSION is measure in one direction; specifically : one of three coordinates determining a position in space or four coordinates determining a position in space and time. Dimension, in common parlance, the measure of the size of an object, such as a box, usually given as length, width, and height.

Key Insights

In mathematics, the notion of dimension is an extension of the idea that a line is one-dimensional, a plane is two-dimensional, and space is three-dimensional. A dimension is how we explain the ability to move through space. Are there more to dimensions than just spatial movement? Learn about dimensions. DIMENSION definition: 1.

Final Thoughts

a measurement of something in a particular direction, especially its height, length, or width…. Learn more. Roughly speaking, it is the number of coordinates needed to specify a point on the object. For example, a rectangle is two-dimensional, while a cube is three-dimensional. The dimension of an object is sometimes also called its "dimensionality."
