Calculate how much gravel you need for a driveway base, landscaping or drainage project. Prevents ordering too little or wasting money on excess material.
Planning calculator only. Do not rely on this page alone for structural design, permitting, code compliance, engineering signoff, procurement quantities, or contractual commitments.
Gravel volume = length × width × depth, converted to cubic yards and tons.
Enter job values, review the estimate, then use the decision hints before ordering or quoting.
| length | width | depth Inches | yards | tons |
|---|---|---|---|---|
| 20 | 40 | 4 | 9.88 | 13.34 |
| 10 | 25 | 3 | 2.31 | 3.13 |
Volume (cu yards) = (Length × Width × Depth) / 27Tons ≈ cubic yards × 1. 35. Add 10–15% for compaction and waste.
Depth is usually 4–6 inches for driveways
Calculate concrete needed for curbs, gutters and driveway edges.
Estimate bricks and mortar for a wall build so you can plan quantities before final layout and waste adjustments.
Estimate slab concrete before you call a ready-mix plant or decide whether bags are enough.
4–6 inches base layer is standard for most residential driveways.
Gravel settles and compacts when rolled — you lose volume after installation.
