Beds, paths & patios
Landscape calculators for mulch, gravel, soil and pavers.
Estimate mulch bags, gravel weight, topsoil volume, pavers, bedding sand, and edging in US customary or metric units.
Outdoor projects often combine area, installed depth, settlement, density, and supplier delivery units. Measure the actual planted or paved shape, then verify whether the supplier quotes loose or compacted material.
Mulch CalculatorConvert bed dimensions and target depth into bulk or bagged mulch.Gravel CalculatorEstimate gravel volume and weight for paths, driveways, and drainage.Topsoil CalculatorPlan topsoil for lawns and raised beds with settling allowance.Paver CalculatorEstimate pavers, bedding sand, and edge length for patios and paths.Paver Base CalculatorEstimate compacted aggregate base volume for patios, paths, and pavers.Sand CalculatorEstimate sand volume, bulk weight, and cost from area, depth, and density.Retaining Wall Block CalculatorEstimate wall blocks and cap units from wall face and product dimensions.Grass Seed CalculatorEstimate seed bags for a new lawn or overseeding from labeled coverage.Sod CalculatorEstimate sod rolls, slabs, and pallets from lawn area and local unit coverage.Polymeric Sand CalculatorEstimate jointing sand bags using paved area and manufacturer coverage.Landscape Rock CalculatorEstimate decorative rock volume, weight, and cost with editable density.Pond Volume CalculatorEstimate pond water capacity from plan dimensions, average depth, and shape.Pond Liner CalculatorSize a rectangular pond liner with depth and edge overlap included.Pool Volume CalculatorEstimate rectangular or oval pool water volume from average depth.Asphalt CalculatorEstimate compacted asphalt tonnage and cost from area, depth, and density.Asphalt Sealer CalculatorEstimate driveway sealer pails from area, coats, and product coverage.
Before calculating
Three checks for a better estimate.
01Use finished depth
Enter the depth the project needs after placement. Settlement and compaction should be separate, editable assumptions.
02Match supplier units
Bag volume, bulk density, cubic-yard delivery, and tonne pricing describe different purchase models.
03Split irregular areas
Break curves and L-shaped beds into simple sections, calculate each section, then combine their quantities.
