Planning assumptions
Use actual board width and the gap required by the selected product. A nominal six-inch board is not necessarily six inches wide. Enter both cutout dimensions for an L-shaped deck; the cutout is at the lower-right corner of this plan.
Rows use full-width boards with the last row ripped to fit. Cut lengths must fit a single stock board; joints and staggered patterns are excluded. First-fit stock packing includes saw kerf between pieces, then adds the entered extra-stock percentage. It is a heuristic, not a guaranteed optimal cutting plan.
Support and joist spacings are layout inputs from your approved design. Moving a post does not check the resulting span. This planner does not size beams, joists, posts, footings, connections or guards. The cost includes boards, entered joist length, posts and your other-cost allowance; add all omitted work and materials explicitly in one currency.
