| Scale | Length | Area | Locale |
| Micro | 1 m - 1 km | 1 m² - 1 km² | local |
| Meso | 1 km - 100 km | 1 km² - 100 km² | regional |
| Macro | 100 km - 10 000 km | 100 km² - 10 000 km² | continental |
| Mega | > 10 000 km | >10 000 km² | global |
Spatial scale provides a "shorthand" form for discussing relative lengths, areas, distances and sizes. A microclimate, for instance, is one which might occur in a mountain valley or near a lakeshore, whereas a megatrend is one which involves the whole planet. A mountain is a Landform that extends above the surrounding Terrain in a limited area with a peak In Geology, a valley (also called a vale, dale, glen or strath and near or in Appalachia, a draw) is A planet, as defined by the International Astronomical Union (IAU is a celestial body Orbiting a Star or stellar remnant that is
It is important to realize that these divisions are more or less arbitrary, and where, on this table, mega- is assigned global scope, it may only apply continentally or even regionally in other contexts. The interpretations of meso- and macro- must then be adjusted accordingly.
