Landscaping Calculators
These tools turn lawn and bed measurements into a buy list — pounds, bags, yards, and tons — using published university and industry rates rather than guesswork.
Mulch
Yards or bags for your beds using the 324 rule, with multi-bed support.
Gravel & Stone
Cubic yards and tons by material, with a compaction allowance for bases.
Topsoil
Yards, 40 lb bags, and approximate weight for beds and raised beds.
Sod
Rolls and pallets with a cutting allowance, phrased the way farms sell.
Grass Seed
Pounds of seed by grass type for a new lawn or overseeding, and the bag to buy.
River Rock
Tons and yards of decorative stone, with depth guidance by stone size.
