Header Size Calculator

What is a Header Size Calculator?

A Header Size Calculator is a web-based tool used to estimate the appropriate size of a structural header, such as a beam or lintel, needed to support the load above an opening in a wall, like a door or window.

It considers factors such as the span of the opening, the type of load (roof, floor, or wall load), and the material of the header to provide an accurate estimate of the header size.

Why Use a Header Size Calculator:?

Header Size Calculators are used for the following reasons:

1. Structural Integrity: To ensure that the header is of adequate size to support the load without compromising the structural integrity of the building.
2. Safety: Proper header sizing is essential for safety to prevent structural failures.
3. Cost Efficiency: Helps in selecting the right header size, avoiding oversizing that can lead to unnecessary costs.
