Tilankoko

Tilankoko is a Finnish noun that means the size or extent of a space. The term is not a fixed technical term in itself but a general descriptor used across fields to indicate how large a given space is. In geometry and mathematics, tilankoko refers to the dimensions of a space: a two-dimensional tilankoko is defined by length and width, while a three-dimensional tilankoko adds height, and higher dimensions are discussed in abstract contexts. In architecture and interior design, tilankoko is commonly expressed in square meters (m²) for floor area or in cubic meters (m³) when volume and ceiling height are included.

In geographic information systems and cartography, tilankoko describes the spatial extent of a dataset or area of interest, often defined by a bounding box or polygon. In real estate and urban planning, it can denote parcel size, floor area, or usable space within a building. The term is frequently used in descriptive phrases such as “tilan koko” or “tilan laajuus,” and its exact interpretation is determined by accompanying measurements and units.

Because tilankoko is context-dependent, translating it into English or other languages requires attention to units (m², m³, ha, etc.) and the relevant discipline. See also pinta-ala (area), tilavuus (volume), dimensio (dimension), and GIS spatial extent.
