Dimensionality, or the nature of movement and location, can become complicated in foreign planes and pocket dimensions.

In physics and mathematics, the dimension of a space or object is informally defined as the minimum number of coordinates needed to specify any point within it.1 The word "dimension" is also used to refer the metaphysical planar properties that governs movement between planes in much the same sense as physical dimensions in the Universe govern movement within it, and is sometimes used to refer specifically to the Transitive Planes.2

Extradimensionality, in turn, refers to positioning and movement in spaces that exist outside of any plane or dimension, such as the location of a demiplanes that exists outside of any other plane.2

Dimensional realms

The term "dimension" can also refer to discrete extraplanar realms that defy categorization by simultaneously overlaying all other dimensions and planes, while also lacking the finite spatial nature of planes.3

Planar scholars uniformly agree that two infinite realms previously classified as demiplanes lack the spatiality and finite size necessary to be classified as either demiplanes or Transitive Planes:3
