The Complete Guide to Landscape Material Calculators

Updated 2026-07-28 · Yardly

Every landscape project bottoms out at the same question: how much stuff do I actually need? Too little and the job stalls; too much and you’re paying to store it. Yardly’s calculators turn dimensions into exact counts and volumes — here’s the map.

Hardscape and concrete

• Concrete Slab Calculator — slabs, footings, pads (cubic yards, bags, cost)
• Fence Post Concrete Calculator — concrete per post and per run
• Paver Calculator — paver counts and base from patio size
• Retaining Wall Calculator — blocks and base from wall face area

Bases and aggregates

• Gravel Calculator — driveways, patios, drainage
• Sand Calculator — paver screed beds, leveling
• River Rock Calculator — decorative beds and dry creek

Soil and garden

• Topsoil Calculator — lawns and beds
• Raised Bed Soil Calculator — box gardens
• Fill Dirt Calculator — grading and raise
• Mulch Calculator — beds and tree rings

Lawn

• Sod Calculator — rolls or pallets with waste
• Grass Seed Calculator — pounds by seeding rate

Whole-project estimators

For a full build, use a project estimator that reuses your dimensions across every material:

• Paver Patio Project
• Retaining Wall Project
• Fence Project
• New Lawn Project

Every calculator and estimator includes a configurable waste margin, so the number you order already covers the usual spillage and cuts. Pick your material above and run the numbers — no account, no email, just the estimate.
