Crushed Stone & Gravel Tonnage Calculator

Crushed stone aggregate weight depends on stone size and compaction density. Standard #57 crushed stone weighs approximately 2,700 lbs per cubic yard, whereas dense crusher run base stone weighs ~2,850 lbs/yd³.

To use the Crushed Stone & Gravel Tonnage Calculator, enter your Project Area Length, Project Area Width, Crushed Stone Layer Depth and other values. The calculator instantly computes Total Weight Required, Total Volume Needed and more. Results update in real time as you change any input — no submit button needed.

How to Use This Calculator

Enter your Project Area Length (e.g. 30 in ft), Project Area Width (e.g. 10 in ft), Crushed Stone Layer Depth (e.g. 4.0 in inches), Crushed Stone / Aggregate Type — choose from #57 Crushed Stone / Wash Gravel (2,700 lbs/cu yd -- 1.35 tons/yd³), Crusher Run / ABC Base (2,850 lbs/cu yd -- 1.43 tons/yd³), Pea Gravel (2,800 lbs/cu yd -- 1.40 tons/yd³), and Waste & Compaction Safety Margin (e.g. 10 in %). Measure twice before entering dimensions — small measurement errors scale up significantly in material estimates.

The Formula

Volume (cu ft) = Length (ft) × Width (ft) × [ Depth (in) ÷ 12 ]

Gross Volume (cu yd) = [ Volume (cu ft) × (1 + Waste %) ] ÷ 27

Total Tons = [ Gross Volume (cu yd) × Material Density (lbs/cu yd) ] ÷ 2,000

Worked Example

30 ft × 10 ft driveway (300 sq ft) with 4-inch #57 crushed stone layer and 10% waste:

Gross Volume = / 27 = 4.07 cubic yards.

Total Weight = / 2,000 = 5.50 US short tons (1 dump truckload).

Understanding Your Result

Construction estimates are starting points — site conditions, material specifications, and local code requirements will affect final quantities and costs. Always obtain at least three contractor bids for major projects. Local building departments can confirm permit requirements and inspection milestones. Add waste factors appropriate to the material type and complexity: 10% for simple rectangular shapes, 15–20% for complex geometries or custom cuts.
