From deck dimensions to purchasable boards
The planner calculates full deck-board rows across the width, boards required along each row, and an allowance for cuts and defects. This produces a more useful retail count than square footage alone. Add picture-frame borders, breaker boards, stairs, and unusual patterns in the extra-board field.
How the common framing takeoff works
Joist count is based on the entered on-center spacing along the deck length. Each joist spans the entered deck width and is converted to the selected stock length. Rim-board material covers both ends of those joists. This does not size members or calculate beams, posts, a ledger, blocking, hardware, or lateral-load connections.
Footings come from the approved plan
The planner deliberately does not invent a footing count. Enter the number and concrete per footing from your approved design. Diameter, depth, frost line, soil, loads, and local code determine the actual requirement.
Before purchasing
- Confirm actual board dimensions, stock lengths, and manufacturer spacing rules.
- Confirm span tables and the complete framing plan with your local building authority or qualified designer.
- Add beams, posts, ledger material, joist hangers, structural fasteners, flashing, railings, stairs, permits, delivery, and tax separately.
- Locate utilities and confirm excavation requirements before digging.
