Landscaping

Mulch, soil, gravel, sand, sod and edging.

• Grass seed calculator — How much grass seed you need, at the rate published for your grass type. Bermuda takes 2 lb per 1,000 sq ft and tall fescue 8 — one rate ruins lawns.
• Gravel calculator — Work out tons and cubic yards of gravel for a driveway, shed base or path. Includes the compaction allowance and per-stone densities most calculators skip.
• Mulch calculator — Work out cubic yards and bags of mulch from your bed area and depth. Includes the coverage per cubic yard at your depth — the figure most calculators omit.
• Paver sand calculator — Work out bags of bedding sand and polymeric joint sand for a paver patio. Uses the ICPI 1 in bedding depth and coverage by joint width, not a flat figure.
• Paver calculator — How many pavers you need, plus the crushed stone base under them — with the compaction allowance and the wider excavation most calculators leave out.
• Sod calculator — Work out pallets, slabs or rolls of sod from your lawn area. Pallet coverage runs from 400 to 700 sq ft by region, so this asks for yours instead of guessing.
• Topsoil calculator — Work out cubic yards and bags of topsoil for a raised bed, lawn or garden. Uses the 0.75 cu ft bag stores actually stock, and allows for settling.
