How estimates work
Every estimate starts with your measurements and ends with assumptions you can inspect.
Measurements first
Tools use the dimensions you enter. Rectangular areas are calculated from length × width; included areas are combined and exclusions are subtracted before any fitting buffer is applied.
Whole packages
Purchase recommendations round up to whole packages. Coverage is a planning assumption, not a promise about a supplier’s packaging. Check the label or ask the supplier before ordering.
Prices are optional
Where a calculator supports cost, the numbers come from values you enter. The result is an estimate of the selected package combination and does not include unentered taxes, site work, labor, or other fees.
