What is a Header Span Calculator?
A Header Span Calculator is a tool used to calculate the span or length of a header beam (lintel) required to support a specific load or span an opening in a building’s structure.
It ensures that the header beam is appropriately sized to carry the load and provide structural support.
Why Use a Header Span Calculator?
- Structural Integrity: Calculating the correct header span is crucial for ensuring that the header beam can safely support the load and prevent sagging or structural issues.
- Material Selection: The calculator allows you to choose the appropriate material for the header based on load requirements and building codes.
- Safety: Using the correct header span ensures the safety of door and window installations and the building’s occupants.

How to Use a Header Span Calculator:
- Input the total load to be supported (in pounds), which includes the weight of the structure or load-bearing elements above the header.
- Select the material for the header (e.g., wood, steel, or concrete) from the dropdown menu.
- Enter the spacing of the header supports (in inches), which is the distance between the points where the header is supported.
- Click the "Calculate" button.
- The calculator will provide the recommended header span (in inches) based on the input parameters, material selection, and safety factors.
Example Calculation:
Let's say you have the following parameters:
- Total Load (L): 10,000 pounds
- Header Material: Steel
- Header Spacing (S): 48 inches
Using these values in the provided HTML code:
- Header Span ≈ (10,000 pounds * 48 inches) / (25,000 psi * 2.0) ≈ 9.6 inches
So, the recommended header span for the given total load, steel material, and header spacing is approximately 9.6 inches.
This calculation ensures that the header can adequately support the load above the opening.
Please note that this is a simplified example, and actual header calculations may involve additional factors and structural engineering expertise.
