Landscape & Earthwork Calculators
Accurate material estimates are critical for landscaping and earthwork — bulk materials like gravel, mulch, and topsoil are sold by the cubic yard or ton, and over-ordering is expensive to haul away. Calculate exactly what you need.
Gravel Calculator
Cubic yards and tons of gravel, crushed stone, and pea gravel.
Mulch Calculator
Cubic yards or bags of mulch for landscape beds and paths.
Soil Calculator
Topsoil and fill dirt volume for lawns, gardens, and grading.
Topsoil Calculator
Topsoil depth and quantity for lawn establishment and garden projects.
Sod Calculator
Pallets and rolls of sod for full lawn installation.
Sand Calculator
Sand for paver bases, mortar, and fill applications.
Paver Calculator
Paver count, bedding sand, and base gravel for patios and walkways.
Asphalt Calculator
Tons of asphalt for driveways, parking lots, and paving projects.
About Landscape & Earthwork Calculators
Landscaping and earthwork projects involve large volumes of bulk material that must be planned carefully. Gravel, mulch, topsoil, and fill dirt are all measured in cubic yards — one cubic yard fills a space 3 feet wide, 3 feet long, and 3 feet deep. Bulk suppliers typically sell these materials loose by the yard or in bags at a significant per-unit premium.
Paver and hardscape projects require a layered base system: typically 4–6 inches of compacted gravel base, 1 inch of bedding sand, and then the pavers themselves. Getting the base right is more important than the surface — a poorly compacted base leads to settling, cracking, and weed intrusion. These calculators help you estimate each layer independently.
Mulch depth significantly affects performance. A 2-inch layer provides basic weed suppression; 3 inches is the recommended depth for most applications; 4 inches is used in areas with aggressive weeds. Fresh mulch decomposes and settles over time, so replenishing annually with 1 inch of new material maintains the desired depth without excessive buildup that can harm plant crowns.
