Gravel Calculator
Estimate gravel volume, supplier-weight-based tonnage, and optional material cost for a rectangular area or known area.
Gravel estimate
Estimate order volume first, then use your supplier's stated density to check weight and pricing.
Recommended order quantity

How this estimate works
The calculator first finds installed volume: volume = area × depth. It applies any optional order allowance after that volume is calculated.
It then estimates weight using weight = volume × density. The result uses the supplier density you enter, so you can compare the order volume with the selling unit on a local quote.
For example, 10 ft × 10 ft at 4 in deep is about 1.23 cubic yards installed. A 10% order allowance produces about 1.36 cubic yards before supplier density and pricing are applied.
Before you order
Confirm the supplier's stated density, selling unit, minimum order, delivery terms, and material description before purchasing. Density can differ with aggregate type, particle-size distribution, moisture, and handling.
The allowance is an editable purchasing buffer only. It does not predict compaction, settling, grading, waste from an irregular layout, or the volume a particular supplier will deliver.
Gravel calculator FAQ
- Why do cubic yards and short tons differ?
- Cubic yards measure volume, while short tons measure weight. The conversion depends on the density supplied for the actual material.
- Does this calculator choose the material or depth?
- No. It estimates a rectangular area using the depth and supplier density you provide. Confirm material selection and project requirements with the relevant supplier or qualified local professional.
Method & sources
Inputs are normalized to metres, square metres, cubic metres, and kilograms before results are converted for display. The calculator does not round internally; display values are rounded only for readability.
Important limits
- This estimates one rectangular area or one known area only; it does not model slopes, curves, multiple areas, or irregular shapes.
- It does not calculate compaction, delivery, taxes, supplier minimums, truck loads, material selection, drainage, or project-specific installation requirements.
- Weight and cost are planning estimates based on the entered supplier density and price, not a supplier quote or order confirmation.
