Structural Calculators
Free tools for sizing beams, estimating truss costs, calculating load capacity, and planning structural elements of your building project. Each calculator shows the formulas used and includes educational guides below the tool.
Most PopularTruss Price Calculator
Estimate roof truss costs including material and labour. Enter span, spacing, truss type, and quantity for an instant price breakdown.
Load-Bearing Wall Calculator
Calculate total load on a bearing wall and estimate the beam size needed for removal. Enter wall dimensions, floors above, and roof load.
Steel Beam Size Calculator
Estimate the required steel beam size for your span and load. Enter span length, total load, and beam type to get section modulus and suggested sizes.
Shed Roof Truss Calculator
Calculate shed truss count, rafter length, lumber quantities, and costs. Enter shed width, pitch, overhang, and spacing for a full material list.
Concrete Reinforcement Calculator
Calculate rebar quantity, spacing, weight, and tie wire for concrete slabs and footings. Enter slab dimensions, rebar size, and spacing.
Wall Framing Calculator
Calculate studs, plates, and headers for framed walls including door and window openings. Enter wall dimensions, spacing, and opening count.
Concrete Block Wall Cost
Calculate blocks, mortar, rebar, and total cost for a concrete block wall. Enter wall dimensions, block size, and mortar joint width.
Deck Weight Limit Calculator
Calculate your deck's load capacity based on joist size, spacing, and wood species. Get dead load, live load, and maximum point load estimates.
Wood Beam Cost Calculator
Compare wood beam costs by species, grade, and size. Estimate material prices for Douglas Fir, Southern Yellow Pine, SPF, and LVL beams with hardware costs included.
Shed Foundation Calculator
Calculate shed foundation requirements for pier blocks, gravel pads, or concrete slabs. Enter shed size and soil type for material quantities and cost estimates.
Pier Footing Size Calculator
Size pier footings based on column load, soil bearing capacity, and frost depth. Get footing width, depth, and concrete volume for decks, porches, and posts.
Deck Joist Span Calculator
Find maximum deck joist spans for 2x6 through 2x12 lumber. Adjust species, spacing, and load to get code-compliant spans and joist counts instantly.
Staircase Dimension Calculator
Calculate stair rise, run, tread count, stringer length, and headroom clearance from floor-to-floor height. Verify building code compliance for residential staircase geometry.
Concrete Slab Weight Calculator
Calculate the weight of a concrete slab by dimensions, thickness, and density. Covers normal-weight, lightweight, and reinforced concrete for structural load planning.
Concrete Curing Time Calculator
Estimate concrete curing time to reach target strength based on mix type, temperature, humidity, and thickness. Plan form removal and loading schedules.
Retaining Wall Block Calculator
Estimate retaining wall block count, base gravel, drainage gravel, and total cost. Enter wall length, height, and block size for a complete material list.
