What Is a Gravel Calculator, Really?
A gravel calculator answers the question that every landscaper, contractor, and DIYer asks before ordering a load of rock: "Given the area of a driveway, path, or foundation, and the desired depth, how many cubic yards or tons do I need?"
The "Mass" Factor: Gravel is typically sold by the Cubic Yard (volume) or by the Ton (weight). A cubic yard generally weighs about 1.4 tons, but density variations between Pea Gravel and Crushed Stone are significant.
"Always order 10-15% extra to account for compaction and settling. Never place decorative gravel directly on soil; it will sink without a proper base layer."
Structural Depth Standards
| Application | Recommended Depth | Material Strategy |
|---|---|---|
| Driveway (Base) | 4 - 6 Inches | Crushed Stone with Fines |
| Driveway (Top) | 2 - 3 Inches | Decorative / Pea Gravel |
| Walkways / Paths | 2 - 3 Inches | Compacted Stone Dust / #57 |
| French Drains | 6 - 12+ Inches | Clean Stone (No Fines) |
Volumetric Computation
Bulk Volume (Yds³)
Ensure all dimensions are in feet before division. 27 is the conversion constant for cubic feet to cubic yards.
Mass Conversion (Tons)
Density values typically range from 1.4 for pea gravel to 1.7 for heavy river rock or wet aggregate.
Civil Aggregate Scenarios
Scenario A: Main Driveway
360 sq ft surface, 6 inches deep. Requires ~6.67 cubic yards. Adding 10% for compaction results in ~11 tons of crushed stone.
Scenario B: French Drain
50 ft trench (1ft wide, 1.5ft deep). Requires 75 cubic feet (~2.78 yds³). Use clean #57 stone to prevent drainage clogging.
Density Multipliers
Logistics Audit
- Verify Supplier Unit (Tons/Yds)
- Account for 15% Compaction
- Check Truck Access Weight Limits
- Calc Separation Fabric Layer
Inventory Failures
Compaction Deficit
Gravel settles by 10-20% when driven over. Failing to order the surplus results in thin base coverage.
Moisture Weight Bias
Wet aggregate can weigh 30% more than dry. Ensure your delivery provider accounts for moisture density shift.
