How decking is estimated
The calculator estimates board runs across the deck width using board face width plus the selected gap, then converts those runs to linear feet and full boards.
board runs ≈ deck width ÷ (board width + gap)
Decking Calculator FAQ
Does this include framing?
No. Joists, beams, posts, hardware and footings are separate.
Does board direction matter?
Yes. This assumes boards run along the entered deck length.
Why add waste?
Cuts, defects and layout can require extra material.
