Door Header Size Calculator

Door Header Size Calculator

A Door Header Size Calculator is a tool used to determine the appropriate size of a header beam for a door opening in construction projects. It calculates the required dimensions of the header based on the span of the opening and the load it needs to support.


The formula for calculating the door header size depends on the specific requirements and building codes of the region. It typically takes into account factors such as the type of construction materials used, the weight of the structure above the door, and the type of load (such as live or dead load).


For example, for a 6-foot-wide door opening with a single-story structure, the calculator may recommend a header size of 2×8 inches. The Door Header Size Calculator is a valuable tool for ensuring structural integrity and safety in door installations.
