What are you building?
Choose a project to open the calculators and planning checks that belong together. Start with dimensions, review the visible assumptions, and keep the estimate tied to your actual product label.
Project paths
Open the tools in project order
Start with the primary material, then move to the next quantity or planning check only when your project needs it.
Patio or walkwayPlan the surface, gravel base, bedding layer, and drainage checks in project order.
Combine pavers, base gravel, bedding sand, edge restraint, joint sand, and overage.
Count surface units · CalculatorPaver CalculatorEstimate paver count from patio dimensions, paver size, and waste.
Estimate base layers · CalculatorPaver Base CalculatorEstimate gravel, bedding sand, cubic yards, tons, and bags.
Check drainage · PlannerPaver Slope & String-Line PlannerBuild grade-stake readings for the surface, bedding, base, and excavation.
Room remodelMove from wall coverage to paint and tile quantities without mixing material assumptions.
Plan patch pieces, project panels, tape, and optional backing from a squared cutout.
Cover walls and ceiling · CalculatorDrywall CalculatorEstimate sheets from room size, wall height, ceiling choice, sheet size, and waste.
Finish walls · CalculatorPaint CalculatorEstimate gallons from wall area, coats, label coverage, and openings.
Plan a tiled surface · CalculatorTile CalculatorEstimate tile pieces and boxes from area, tile size, and layout waste.
Deck surfaceEstimate straight-run deck boards, then compare the same math with a worked 12 × 16 example.
Fence runCount pickets for a straight fence run and compare the result with a 100 ft worked example.
Garden bed or pathEstimate mulch or gravel volume, then check the depth assumption before buying bags or bulk material.
Estimate cubic yards and bags from bed dimensions, depth, and overage.
Build a path or strip · CalculatorGravel CalculatorEstimate cubic yards and tons from area, depth, density, and overage.
Choose a depth · GuideMulch Depth and TypesCheck how depth changes coverage before entering the final estimate.
Tile floor or shower basePlan tile quantity, dry-pack mortar volume, and a printable estimate worksheet as separate steps.
Estimate pieces and boxes from surface area, tile size, pattern, and waste.
Estimate a mortar bed · CalculatorDeck Mud CalculatorEstimate dry-pack volume, mix quantities, bags, slope, and waste.
Prepare a takeoff · WorksheetTiling Estimate WorksheetUse a printable planning sheet before comparing products or box coverage.
Starting tools
Start with a calculator
One primary calculator from each project path. This order reflects the project map, not a traffic ranking.
LandscapingPaver CalculatorEstimate pavers for a patio or walkway from project dimensions, paver size, and a waste factor.
DrywallDrywall CalculatorEstimate drywall sheet count for room walls, with an option to include the ceiling and choose common sheet sizes.
DeckingDeck Board CalculatorEstimate decking boards, plus a rough material list (joists, screws, hidden fasteners, and fascia) and an optional cost from your own price per board.
FencingFence Picket CalculatorEstimate pickets for a straight DIY fence run from fence length, actual picket width, spacing gap, and waste factor. Plan posts, rails, gates, and hardware separately.
LandscapingMulch CalculatorEstimate mulch volume in cubic feet and cubic yards, with optional settling overage and bag count.
Flooring & TileTile CalculatorEstimate tiles needed for a floor or wall area, with tile size, waste factor, a layout pattern preview, and an optional user-entered tile cost.

Practical guides
Check the assumption before you calculate
These guides help choose inputs such as slab thickness, mulch depth, paver base depth, slope, and overage.
Use this guide to compare mulch depth, cubic yards, 2 cu ft bags, and settling overage before estimating a landscape bed.
Concrete guideRecommended Concrete Slab Thickness for Patios, Sheds, and DrivewaysLearn how slab thickness affects concrete volume, bag count, and planning assumptions before estimating material quantity.
Pavers guideHow to Clean Paver Joints Before Re-SandingCheck joint depth, debris, weeds, loose pavers, drainage, and normal new paver gaps before adding joint sand or polymeric sand.
Pavers guidePaver Patio Material ChecklistUse this material-first checklist to prepare planner inputs for base gravel, bedding sand, paver count, edge restraint, joint sand, and overage.
Pavers guideCan You Lay Pavers on Sand Only?Use this decision checklist to separate bedding sand from structural base material before planning a patio, walkway, or small reset.
Pavers guideWhy Are My Pavers Sinking?Match sinking, rocking, low edges, joint washout, and drainage problems to likely causes before planning a repair material list.
