Reference tables
Look-up charts built from stable conventions — material coverage (cubic yards by area & depth), grass-seed rates, fertilizer NPK math, sod coverage, gravel & stone density, paver & block coverage, fence spacing, and the watering & plant-spacing conventions.
Material coverage: cubic yards by area & depthCubic yards of mulch, soil, gravel or sand by area and depth (÷324) and bags of 2 cu ft per cubic yard, as labeled planning conventions — behind the material calculators.Grass seed rate by grass typeSeeding rate in pounds per 1,000 sq ft by grass type, for new lawns and overseeding, as labeled planning typicals — behind the grass-seed calculator.Fertilizer rate & the NPK mathHow much fertilizer product to apply per 1,000 sq ft at 1 lb of nitrogen for common %N products, as labeled planning math — behind the fertilizer calculator.Sod roll & pallet coverageSod roll and pallet coverage (~10 sq ft per roll, ~450 sq ft per pallet) with pallets for common lawn sizes, as labeled planning typicals — behind the sod calculator.Gravel & stone density (tons per cu yd)Approximate tons per cubic yard for gravel, sand, topsoil and river rock, as labeled planning typicals — behind the gravel and stone calculators.Paver & retaining-wall block coveragePavers per 100 sq ft by nominal size and retaining-wall block face coverage, as labeled planning typicals — behind the paver and retaining-wall calculators.Fence post & picket spacing conventionsPost spacing, picket width and gap, and rails per section, as labeled planning conventions — behind the fence-materials calculator.Watering identity & plant spacingThe 0.623 gal per sq ft per inch watering identity and plants per 100 sq ft by spacing (square and triangular), as labeled planning conventions.
