For either base, compacted volume = area × specified depth. The tonnage changes with the actual aggregate's bulk density, so compare supplier-specific tons per cubic yard and gradation rather than assuming limestone and generic crushed stone weigh the same.
Compare crushed-stone and limestone base on the same required compacted volume. Convert that volume to tons separately for each actual supplier aggregate because rock source, gradation, moisture, and voids affect bulk density.

Published by BuildYard. The guide reflects BuildYard's calculation methodology and editorial standards and does not replace project-specific professional advice.
Calculate the same compacted design volume for each candidate material.
Keep depth and footprint constant when comparing alternatives.
Tons = compacted cubic yards × verified supplier conversion for that aggregate.
Source rock, gradation, moisture, and voids influence bulk density.
Account for compaction and placement allowance explicitly.
Compare delivered cost only after converting both options to the same required compacted volume.
Base suitability depends on gradation, durability, drainage, and project requirements, not just rock type.
Quantity comparison cannot approve a material substitution.
Gravel Calculator estimates gravel cubic yards, tons, and truck loads for paths, pads, drainage zones, and general aggregate placement.

| Step | Calculation | Result |
|---|---|---|
| Depth | 6÷12 | 0.5 ft |
| Volume | 500×0.5 | 250 cu ft |
| Cubic yards | 250÷27 | 9.26 yd³ |
| Tons | 9.26×each supplier factor | Compare separately |
Current manufacturer data, supplier specifications, drawings, field measurements, applicable codes, permit requirements, and qualified professional guidance can take priority over a general-purpose planning estimate.
