suorakulmaispintaisessa

Suorakulmaispintaisessa is a Finnish adjective that describes an object, area or surface that has a rectangular shape. The word is literally composed of suorakulmias, meaning “rectangular”, with the suffix –pinta that conveys the idea of a surface or face, and –inen which turns it into an adjective. The form –issa is the inessive case, used to indicate being within or inside such a surface, so suorakulmaispintaisessa translates roughly to “in a rectangular‑sided surface”.

The term is frequently used in Finnish architecture, engineering and design to describe floor plans, panels, screens, paintings and other two‑dimensional elements whose geometry is defined by four right‑angled corners. It also appears in technical documentation when specifying dimensions of rooms, circuit boards, Mach‐inable panels, or photographic frames. In construction it may refer to a rectangular layout of walls or a wall surface that is flat and rectangle‑shaped. In art it denotes canvases whose proportions are defined by a perfect rectangle, often combining height and width in preferred ratios such as 1:1.5 or 3:2.

Because the adjective can be used both as a descriptive attribute (suorakulmaispintainen rakenne) and as a locative case (suorakulmaispintaisessa tilassa), it is versatile in Finnish technical discourse. It plays a role in spatial planning, providing a clear dimensional reference that facilitates measurement, construction, and visual balance.
