## How the Calculator Works

It adds up the wall area from the outside measurements of your house, adds the triangle-shaped gable ends, takes out a share for windows and doors, then adds a waste allowance for the material you pick.

-   Wall area = perimeter × wall height
-   Each gable ≈ width × width ÷ 8 (a typical roof pitch)
-   Openings are subtracted as a percentage of the wall
-   Waste covers cuts, overlaps and trim pieces
