- For
- DIY homeowners planning a rectangular deck
- Worth noticing
- It estimates board counts from rows and available stock lengths, and explicitly says its joist spacing is not a span-table check.
Field notes
The page explains that it counts rows rather than dividing deck area by board area, and that whole stock boards are selected to cover those rows. When no stock length covers a row, it describes splicing from available lengths with the least waste, while noting that butt joints must land on a joist. Optional cost estimates use editable prices; the displayed defaults are identified as ballpark figures.
