DeckMate Live

Plan deck materials without spreadsheets or guesswork. DeckMate turns your deck dimensions and chosen materials into a clear estimate for deck area, board rows, stock board count, total linear decking, joists and screws. Choose metric or imperial units, enter board size and gap, set joist spacing, add a waste allowance, and choose screws per board-to-joist fixing. Results update instantly and remain easy to scan on site or at the supplier. DeckMate works fully offline. There are no ads, accounts, analytics or network requests. A persistent light or dark theme keeps the interface comfortable in the workshop or outdoors. Estimates support early material planning only. Confirm spans, structural design, fasteners and local building-code requirements with qualified professionals and product suppliers.
