Türposition

Türposition is a term used in German-language architectural and building-automation contexts to refer to the spatial state and orientation of a door leaf within its frame. It describes whether a door is closed, ajar, partially open, or fully open, and the angle between the leaf and the frame. The concept also includes the swing direction (left- or right-handed) and the side of the hinges. In technical documentation, Türposition helps communicate how a door sits in a doorway in a given plan, design, or moment of operation.

In architectural planning and construction, Türposition is documented on floor plans and in BIM models with symbols for door swing and opening arc. This information influences required clearance, egress routes, accessibility, and the selection of hardware such as closers, stops, and locks. It also affects interior layout decisions and obstruction checks.

In building automation and safety systems, Türposition is monitored by sensors that report the door state to control units. This enables automated lighting, climate control, access control, and safety interlocks. Correctly specified Türposition data supports efficient navigation in complex buildings and compliance with codes for egress width and maneuvering space.

Measurement and nomenclature: Türposition is typically expressed as an opening angle (0° for closed, up to a maximum defined by the door configuration) and as a categorical state (closed, ajar, half-open, open). The term may be used interchangeably with Türstellung in some contexts.
