horizontality

Parallel to ground

Horizontality is the quality or state of being horizontal—parallel to the horizon or to a flat surface.

The term appears most often in technical, architectural, or artistic contexts where the orientation of lines, surfaces, or structures matters.

The horizontality of the prairie landscape creates a sense of endless space.

It contrasts with verticality and can describe both physical arrangements and abstract concepts like organizational flatness.
