How deck boards are estimated
The deck width is divided by the installed board module (board width plus gap). Runs are multiplied by deck length and waste, then divided by stock board length.
Deck Board Calculator FAQ
Does this include framing?
No. Joists, beams, posts, hardware and footings are separate.
Does board direction matter?
Yes. This calculator assumes boards run along the entered deck length.
Should I add more waste for diagonal decking?
Usually yes, because diagonal layouts create more cuts.
