Rafter Span Calculator
A Rafter Span Calculator is an essential tool for construction projects, helping determine the length of rafters needed for roof structures. By inputting the span of the building and the pitch angle, the calculator provides accurate measurements for rafter span, ensuring proper support and stability. This tool simplifies complex calculations, making it easier for builders, architects, and DIY enthusiasts to plan and execute roof constructions with confidence.
How to Use the Rafter Span Calculator
To use the Rafter Span Calculator, first enter the span of the building (S) in feet or meters and the pitch angle (A) in degrees into the respective input fields. Click "Calculate" to get the rafter span results in both feet and meters. The calculator will display the calculated values along with a step-by-step explanation of how the results were derived. If needed, click "Clear" to reset the fields and start over.
