Warnings

Roll plan requires seams. Installer should verify seam placement, pile direction, and pattern matching before ordering.

Assumptions

All dimensions are normalized to integer inches before calculation.

Waste and overage are applied sequentially and are not interchangeable.

Roll geometry captures carpet/sheet-goods offcut loss, so percentage waste is not also applied.

Quantities are estimates; verify before ordering. Not a substitute for a professional on-site takeoff on complex jobs.
