This calculator provides usage estimates only. Variations in measurements, waste, and wall shapes can alter the results of your calculations. Collins Products is not responsible for calculated quantities that are not exact for your job.

*If you've chosen lap siding, this estimate allows for a 1" overlap and assumes a 5% waste factor. If you've chosen panel siding, this estimate assumes a 10% waste factor for cutting and fitting.
