Oviaukko

Oviaukko is a Finnish architectural term meaning the doorway opening in a wall or partition that is sized to fit a door and its frame. The term refers to the physical aperture through which a door can swing and which defines the boundary between rooms or spaces in a building. Oviaukko is used in construction drawings, architectural specifications, and interior design discussions to distinguish the opening from the door itself.

In practice, an oviaukko includes the width and height clearance necessary for the door leaf, jambs, and hardware, as well as any required swing clearance. The size depends on standard door dimensions in the region, wall thickness, and whether the opening is for a single or double door. In building plans, dimensions are given to ensure proper installation and alignment with the door frame.

Etymology: The word is a compound of ovi (door) and aukko (opening). In Finnish, ovi means door and aukko means hole or opening; together they describe the space that must remain open when the door is absent or when calculating installation.

Context and usage: This term is primarily used in technical contexts; in casual language people may simply refer to the doorway. There is no widely recognized concept, organization, or notable entity by the name oiaukko in major reference works. When translating, oviaukko is commonly rendered as "door opening" or "doorway."
