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. Raised Garden Bed Boards, posts, screws and soil — with the height your bed will actually be.
