Quarry
Landscape and hardscape calculators
How much to order for a pad, a bed, a fill, a sand layer, a fertilizer application, or a lawn of sod. Yards, tons, bags, pounds of product, and rolls, with the density or the analysis written next to the answer.
Gravel Calculator
Gravel calculator for tons and cubic yards. #57, pea gravel, crusher run, and river rock, with waste and a truckload count.
Mulch Calculator
Mulch calculator for bulk yards and 2 cubic foot bags. Depth, shape, and a waste percent.
Soil Calculator
Topsoil calculator for bulk yards and bagged soil, with a settle allowance so the bed stays full.
Stone Calculator
Stone and rock calculator for #57, river rock, flagstone, and crushed stone. Tons and cubic yards from a depth.
Dirt Calculator
Fill dirt calculator for cubic yards and tons, with a compaction allowance and an excavation swell factor. Not a topsoil calculator.
Sand Calculator
Sand calculator for bulk fill, paver bedding sand, and polymeric joint sand. Tons, cubic yards, and bags. The bag coverage chart wins.
Paver Calculator
Paver calculator for paver count, compacted base, bedding sand, and edge restraint. Base depths are typical guidelines, not a structural design.
Fertilizer Calculator
Fertilizer calculator for N-P-K product rates. Pounds per 1,000 square feet, per acre, and bags. The product label and a soil test take precedence.
Sod Calculator
Sod calculator for square feet, rolls, and pallets. Shapes add and subtract. Prices are yours. Optional topsoil and a starter-product bag count.
Plant Spacing Calculator
Plant count for square or triangular on-center spacing. Layout math only. The plant tag sets the distance.
Grass Seed Calculator
Grass seed for a new lawn or an overseed, from extension starting rates and an optional pure-live-seed adjustment. The bag label wins.
How these calculators work
Volume is the shape times the depth. A rectangle is length × width × depth. A circle is π × radius² × depth. A triangle is ½ × base × height × depth. Divide cubic feet by 27 for cubic yards. Waste is a percent on top of that. Soil also takes a settle allowance, so the bed is still full after it drops.
The tons-per-yard figures are loose ordering weights used to plan a delivery: #57 at 1.40, pea gravel at 1.30, crusher run at 1.50, river rock at 1.35, hardwood mulch at 0.40, screened topsoil at 1.10. Moisture and the quarry ticket override every one of them. A “10-yard truck” here is a planning count, not a legal payload. The cubic yard calculator is the same geometry with the weight left off.
Fill dirt is the grading and backfill calculator, not the topsoil one. It adds a compaction allowance to the finished hole, and a swell factor when the dirt is hauled away. Sand covers a bulk fill, a 1 inch paver bedding layer, and polymeric joint sand. The coverage chart on a polymeric bag still wins.
The paver calculator counts pavers from the module, including the joint, then the compacted base, the bedding sand, and the edge restraint. Base depths are typical guidelines. A driveway or a poor soil follows the paver maker or a designer. The fertilizer calculator turns an N-P-K analysis into pounds of product. The bag label and a soil test still win. The sod calculator counts rolls and pallets from the shapes you add and subtract. The farm’s coverage and the product label still win. The plant-spacing calculator counts centers on a square or triangular grid. The plant tag still sets the distance. The grass-seed calculator uses extension starting rates. The bag label still wins.
