Railing layout
Work from a clear opening, post-centre runs, or the complete guard outline.
Baluster spacing
Balance a clear opening with equal gaps and a whole baluster count.
Railing posts
Lay out post locations and equal spans across straight or connected runs.
Railing materials
Estimate posts, balusters, unspliced rail stock, waste, and optional cost.
Deck surfaces and finishes
Plan walking boards, exposed edges, grade-following skirting, and wood finish coverage. The finish tool also handles fence components.
Deck boards and fasteners
Plan board rows, stock, cuts, reusable offcuts, and fastener packages.
Deck fascia stock and joints
Measure edges, returns and interruptions with supplied joints and physical stock cuts.
Variable-height deck skirting
Record grade stations, access openings and panel seams; nest the physical sheet blanks.
Outdoor wood exposed surfaces
Count selected faces and edges, blocked surfaces and label-based container purchases.
Fences and gates
Choose a material system, then check post layout or a measured gate opening separately.
Wood fence materials
Estimate posts, boards or panels, rails, fasteners, caps, and entered gate materials.
Chain-link materials
Estimate mesh rolls, top rail, posts, gates, tension wire, and optional concrete.
Selected vinyl fence system
Reconcile documented panels, post roles, gate kits and exact system parts.
Fence posts
Count line, terminal, corner, and gate posts for a measured layout.
Gate opening and clearance
Record clear openings, selected hardware allowances, leaf sweeps, ground samples and obstacles.
Concrete and aggregate
Take off supplied hole or slab geometry, compare fill orders, or count products for prescribed joints.
Concrete for post holes
Convert cylindrical post-hole measurements into volume and whole bags.
Concrete slab and supplied reinforcement
Reconcile measured thickness zones, forms, selected base and approved bar-mark schedules.
Aggregate and fill supplier orders
Compare exact bag, volume and weight quotes, documented conversions, minimums and delivery.
Concrete joint and crack sealant
Record measured joint groups, prescribed profiles, exact cartridge yield and selected backer rod.
Yard and landscape
Measure a footprint, count patio or bed materials, transcribe wall courses, or take off an already-designed ordinary yard drain.
Irregular footprint measurement
Record convex corners or measured triangles, exclusions, checks and area uncertainty.
Paver patio materials
Estimate pavers, layers, joint products, edge restraint, spikes, fabric, and packages.
Raised-bed frames and fill
Use selected corner assemblies and actual boards for multiple beds, physical cuts and inside fill.
Selected retaining-wall courses
Count straight and stepped courses from a supplied design, documented patterns and cap joints.
French drain grade and materials
Sketch optional station depths and estimate gravel, pipe stock, fittings, and fabric for a planned yard trench.
Shed and roof
Compare shed support paths, check equipment entry geometry, or count covering across measured roof planes.
Shed foundation chooser
Compare a pad, slab, piers, blocks, or skids, then sketch the selected takeoff.
Shed equipment entry and ramp fit
Compare measured doorway, equipment and selected ramp profiles with sampled interference checks.
Multi-plane roof takeoff
Compare shingle and metal-panel quantities across pitched roof planes.
Interior finishes and insulation
Lay out drywall on measured surfaces or plan an insulation layer from climate and existing R.
Stair layout
Reconcile whole risers, treads, and a reviewed stringer profile before planning stock.
Construction measurement
Measure surface coverage and bulk layers before choosing material orders.
Cubic Yard Calculator
Add measured bulk-material sections in feet/inches, yards or metres and compare cubic feet, cubic yards and cubic metres without hidden allowances.
Gravel Calculator
Measure driveway, shed-base, patio, walkway or fill sections, add optional extra volume, and estimate pounds and short tons using your entered density.
Construction Square Footage Calculator
Measure room, deck, patio, lot and irregular construction coverage with rectangles, triangles, circles and trapezoids, keeping gross, excluded and net area separate.
