3

Compare, then cut

Why courses?A deck is a surface to cover. The planner keeps pieces in courses, places seams on conceptual joist lines, and tracks which stock board supplies each cut.

Same deck, four approaches

Compare board directions

Each option uses the same boards, gaps, seam rhythm, joist spacing, and offcut rule. Ranked by estimated waste, then purchased length.
