The macroscopic scale is the length scale on which objects or processes are of a size that is measurable and observable.

When applied to phenomena and abstract objects, the macroscopic scale describes existence in the world as we perceive it, often in contrast to experiences (microscopy) or theories (microphysics, statistical physics) considering objects of geometric lengths smaller than one millimeter.

A macroscopic view of a ball is just that: a ball. A microscopic view could reveal a thick round skin seemingly composed entirely of puckered cracks and fissures (as viewed through a microscope) or, further down in scale, a collection of molecules in a roughly spherical shape.

In classical mechanics, describing the movements of the above mentioned ball, can be considered a mainly macroscopic theory; on the much smaller scale of atoms and molecules, classical mechanics no longer applies and the movement of particles is described by quantum mechanics. As another example, near the absolute minimum of temperature, the Bose–Einstein condensate exhibits elementary quantum effects on macroscopic scale.

The term "megascopic" is a synonym. No word exists that specifically refers to features commonly portrayed at reduced scales for better understanding, such as geographic areas or astronomical objects. "Macroscopic" may also refer to a "larger view", namely a view available only from a large perspective. A macroscopic position could be considered the "big picture".

The opposite to the macroscopic scale is the microscopic scale: objects smaller than those that can easily be seen by the naked eye and that require a lens or microscope to see them clearly.
