Openingsbredd

Openingsbredd is a term used in architecture, engineering, and construction to refer to the width of an opening in a structural element such as a door, window, arch, or passage. The measurement describes how much horizontal space is available for movement through that opening and is a key parameter in planning, design, and procurement.

Measurement is typically defined as the clear width—the distance between the inner faces of the surrounding jambs. In drawings, both net (clear) width and gross width (including frame) may be shown. When openings are irregular, the width is taken as the maximum unobstructed dimension at a standard reference height, commonly near floor level for doors. Trim, handles, and frame elements are often excluded in the clear width.

Standards for openingsbredd vary by country, building type, and usage. Building codes and accessibility guidelines commonly set minimum clear widths to ensure safety and usability. A widely cited value for accessible doors is approximately 800 millimeters or more, with some regulations requiring 860–900 millimeters or greater. Wider openings are typical in offices, public buildings, and spaces designed for high throughput or wheelchair access.

Applications and implications: openingsbredd affects traffic flow, furniture layout, ventilation, and security. It is used in architectural drawings, construction documents, and cost estimates, and it interacts with related dimensions such as opening height and opening area. In multilingual contexts, the term aligns with equivalents describing the width of openings in regional building practice.
