Pergola Span Calculator

What Is a Pergola Span Calculator?

A pergola span calculator is a tool that helps determine the maximum distance between supports for a pergola beam.

It takes into account factors such as the type of wood, the size of the beam, and the expected load the beam will need to carry.

Why Use a Pergola Span Calculator?

Using a pergola span calculator ensures that the beams of your pergola are adequately sized and spaced to support the load while maintaining structural integrity.

Without proper calculation, there’s a risk of sagging, instability, or potential structural failure.

How to Use a Pergola Span Calculator?

1. Select the type of wood you plan to use for your pergola from the dropdown menu.
2. Enter the size of the beam (width) in inches.
3. Enter the load that the beam will need to support (lbs per square foot).
4. Click the “Calculate” button.
5. The calculator will provide the maximum span (distance between supports) for the pergola beam without additional support.

How Far Can a Pergola Beam Span Without Support?

The maximum span of a pergola beam without support depends on various factors such as the type of wood, beam size, load, and local building codes.

Using the provided calculator, you can input these factors to get an estimated maximum span.

However, it’s recommended to consult a structural engineer or refer to local building codes for accurate calculations that consider specific project requirements and safety standards.

Example Calculation:

Let’s say you’re using cedar wood for your pergola, with a beam size of 6 inches and a load of 20 lbs/ft². According to the formula used in the calculator, the maximum span without support might be calculated as approximately 15.00 feet.
