LvL Header Span Calculator

What is an LVL Header Span Calculator?

An LVL Header Span Calculator is a tool or web application used to determine the maximum allowable span for LVL headers (Laminated Veneer Lumber) used in framing construction.

The calculator calculates the required LVL header size based on parameters such as the LVL type, load type (uniform or concentrated), and the dimensions of the header (width and height).

Why use an LVL Header Span Calculator?

Using an LVL Header Span Calculator is beneficial for several reasons:

• Safety: It ensures that LVL headers used in construction are appropriately sized to support the intended loads, preventing structural failures.
• Efficiency: It helps optimize header size and configuration, reducing material waste and construction costs.
• Compliance: It ensures compliance with local building codes and engineering standards, which may specify allowable spans and header sizes.
• Precision: It provides precise calculations based on engineering principles and standardized data.

How to use an LVL Header Span Calculator:

To use an LVL Header Span Calculator:

• Select the LVL type you plan to use (e.g., LVL 1.9E, LVL 2.0E).
• Choose the type of load (uniform or concentrated) that the header will be subjected to.
• Enter the header width and height in inches.
• Click the "Calculate" button.
• The calculator will display the maximum allowable span for the LVL header based on the entered parameters.

Example :

Suppose you are using LVL 1.9E and want to support a uniform load with a header that is 9.25 inches wide and 5.25 inches high.

You would select these parameters in the calculator and click "Calculate."

The calculator might display a maximum allowable span of 14 feet based on your selections.
