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.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.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.
