Pergola Span Calculator

What is a Pergola Span Calculator?

A Pergola Span Calculator is a tool that helps you determine the appropriate beam and rafter spans for building a pergola.

It takes into account factors like the pergola’s width, depth, and the type of material (e.g., wood, steel, aluminum) used for construction.

Why Use a Pergola Span Calculator?

Using a Pergola Span Calculator is important because it ensures that your pergola’s structural elements (beams and rafters) are properly sized to support the load and provide the desired aesthetic.

It helps prevent issues like sagging and overloading.

How to Use the Pergola Span Calculator:

1. Input the pergola's width (in feet).
2. Input the pergola's depth (in feet).
3. Select the material you plan to use for the pergola (e.g., wood, steel, aluminum).
4. Click the "Calculate" button to determine the recommended maximum beam and rafter spans based on the selected material.

Example Calculation:

• Pergola Width: 12 feet
• Pergola Depth: 10 feet
• Material: Wood

Upon clicking "Calculate," the calculator would recommend the maximum beam span and rafter span for a wood pergola based on the given dimensions.

The result would be displayed as "Recommended Maximum Beam Span: 18.00 feet" and "Recommended Maximum Rafter Span: 15.00 feet," where Maximum Beam Span: 18.00 feet and Maximum Rafter Span: 15.00 feet are the calculated spans for the selected material.
