Deck Beam Calculator
Typical residential deck beam span guide (reference table): doubled 2x8 → max 6 ft span, doubled 2x10 → max 8 ft span, doubled 2x12 → max 10 ft span. Always verify against local code span tables and actual joist span/spacing.
Deck Board Calculator
Board count = ceil(deck area x 1.10 waste / (board width ft x board length ft)); assumes standard 1/8-1/4 in gap spacing between boards, included in the nominal board width.
Deck Joist Calculator
Joist count = ceil(deck width ft x 12 / spacing in) + 1. Standard deck joist spacing is 16 in OC (or 12 in OC for some decking materials).
Deck Post Calculator
Post count = ceil(beam length ft / post spacing ft) + 1. Deck support posts are typically spaced every 6-8 ft along a beam.
Fence Material Calculator
Combines post count (ceil(length/spacing)+1), rail count (2-3 rails per section x section count), and picket count (fence length in / picket spacing in).
Fence Panel Calculator
Panel count = ceil(fence length ft / panel width ft), using standard 6 ft or 8 ft pre-built fence panels.
Fence Post Calculator
Post count = ceil(fence length ft / post spacing ft) + 1, using standard 8 ft OC (or 6 ft OC) post spacing.
