Cubic Yards
Estimated Tons
Gravel Calculator
The core benchmark calculator. Determine cubic yards, tons, and bags for standard gravel, pea gravel, and drainage rock with custom pricing estimator.
Depths: 2″ – 4″
Gravel Driveway Calculator
Engineered for rural roads, private lanes, and residential driveways. Computes subbase foundation rock, driveway center crowns, and multi-tier depths.
Crowning: ½” / ft
Crushed Stone Calculator
Calculates clean #57 stone, crusher run (#411), and dense graded aggregate (DGA). Includes gradation density conversions for drainage and structural pads.
Grades: #57, #411, DGA
Decomposed Granite Calculator
Bespoke algorithm for DG trails, bocce courts, and rustic patios. Automatically calculates 20% to 25% compaction settling loss and delivered bulk tonnage.
Compaction: +20% to 25%
Free Asphalt Calculator
Estimates hot mix asphalt tonnage, square footage coverage, binder courses, wearing courses, and material expenditure for residential driveways and lots.
Depth: 2″ – 3″
Mulch Calculator
Calculate exact bulk cubic yards or retail bag quantities (2 cu ft and 3 cu ft) for planting beds, tree rings, and weed suppression layers.
Bags: 13.5 per yd³ (2 cu ft)
Paver Base Calculator
Dual-layer calculator built for patios and walkways. Separately calculates the crushed stone subbase layer (4″–6″) and the coarse bedding sand layer (1″).
Sand Layer: 1″ Screed Sand
Rip Rap Calculator
Engineered for steep bank stabilization, drainage channels, culvert outlets, and retention ponds. Factors in slope angles, D50 stone sizing, and truckloads.
Depths: 12″ – 24″ Rock
Road Base Calculator
Heavy-duty road base and aggregate base course (ABC) calculator. Designed for farm equipment lanes, commercial truck pads, and reinforced subgrades.
Depths: 6″ – 10″ Base
Rock Calculator
Multi-stone decorative rock estimator. Features specific density presets for river rock, Mexican beach pebbles, red lava rock, granite, and field boulders.
Outputs: Yards, Tons & Bags
Sand Calculator
Calculates quantities for concrete sand, mason sand, playground sandboxes, swimming pool foundations, and paver joint locking sand with wet vs. dry densities.
Moisture: Dry & Wet Factored

Typical Outdoor Layering Guide
Never under-order materials again. Review standard construction strata layers from base excavation to final decorative surface.
Road Base / Crusher Run
4″ to 8″ compacted thickness of heavy angular aggregate with fines. Prevents rutting and distributes heavy wheel loads.
#57 Clean Crushed Stone
Clean 3/4″ fractured stone without fines. Perfect for free-draining French drains, shed pads, and permeable driveway cores.
1″ Coarse Bedding Sand
Uniform uncompacted coarse concrete sand screeded smooth before laying pavers. Never use stone dust or mason sand.
DG, River Rock or Gravel
2″ to 3″ decorative top dressing layer providing traction, aesthetic texture, and erosion resistance.
North American Aggregate Densities & Compaction
Standard density benchmarks based on USGS and state DOT highway construction standards.
