Macroscopic scale

Explanation:

Subatomic scale is the scale at which atomic constituents, such as nucleus which contains protons and neutrons, and electrons, which orbit in  the elliptical paths around nucleus exists.

Miniscopic scale is a reference scale and is not a standard scale for measurement. Usually, this refers to minute objects.

Atomic scale is the scale which is at size of the atoms.

Macroscopic scale is length scale on which the objects or the phenomena are enough large to be visible with naked eye, without magnifying the optical instruments. It is the largest scale.

Microscopic scale is scale of the objects that require microscope to see them.
