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.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.Maximum 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.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.[su_note note_color="#F2F2F2 " text_color="#333333" radius="3" class="" id=""]Like this post?
