Decking & framing project calculators
Deck material estimates work best when the surface and framing are considered together. Start with the deck dimensions and board layout, then use the framing plan to estimate connectors and concrete. The calculators estimate quantities only; follow your approved design, local building requirements, and each connector manufacturer’s instructions for structural details.
1. Estimate deck boards and layout
Enter the finished deck length and width, board dimensions, and spacing. Board direction and available stock lengths affect cuts and waste, so compare the result with your actual layout before ordering.
- Decking calculator — estimate boards, joists, and fasteners for the deck dimensions.
2. Calculate joist hangers and fasteners
Use the joist count from your framing plan or the decking estimate as a starting point. Hanger placement and fastener schedules vary with the connection and connector model. Enter the quantities specified by the plans and manufacturer, rather than treating default example values as a structural specification.
- Joist hanger calculator — total hangers and fastener boxes from joist count.
3. Estimate concrete for post footings
When the plan calls for concrete footings, calculate the volume from the specified footing dimensions and number. Confirm footing size, depth, reinforcement, and local requirements with the project plans and relevant building authority.
- Concrete calculator — estimate concrete volume for footings and other pours.
