Crusher Run Calculator: How Much Crush and Run Do I Need?
Crusher run calculator helps you determine the exact amount of crush and run gravel required for your project. Whether you're building a new driveway, repairing a base layer, or installing a patio, our 2026 tool accounts for compaction, material density, and US standard measurements. Stop over-ordering or running short — get precise tons, cubic yards, and truckload estimates in seconds.

| Compacted Depth | Coverage per Ton (sq ft) | Coverage per Cubic Yard (sq ft @ depth) | Recommended Use |
|---|---|---|---|
| 2 inches | ~120 sq ft | ~162 sq ft | Walking paths, thin base |
| 4 inches | ~60 sq ft | ~81 sq ft | Residential driveways, paver base |
| 6 inches | ~40 sq ft | ~54 sq ft | Heavy truck driveways, road base |
| 8 inches | ~30 sq ft | ~40 sq ft | Commercial / industrial sub-base |
2026 Project Prep Checklist: Crush and Run Driveway
- ✅ Measure driveway area accurately (length x width).
- ✅ Choose correct compacted depth: 4” for cars, 6” for trucks/RVs.
- ✅ Account for compaction factor: loose material compresses ~20-25%.
- ✅ Order extra 10% for edges and settling.
- ✅ Schedule delivery after grading and geotextile fabric (prevents mixing).
- ✅ Compact every 2-3 inches with a vibratory plate compactor for 2026 best practices.
How to Calculate Crusher Run for a Driveway (Step-by-Step)
Follow this proven method to get professional-grade estimates for crush and run gravel without guesswork.
- Measure the project area – length and width in feet. For irregular shapes, break into rectangles.
- Decide compacted depth – most US driveways require 4 to 6 inches after compaction.
- Calculate compacted volume (cubic yards): (Length × Width × Depth in inches) ÷ 324.
- Apply compaction factor – Multiply compacted volume by 1.25 (standard for crusher run).
- Convert to tons – Loose cubic yards × density (1.4 tons/cy) = total tons needed.
- Add waste factor – Add 5-10% for spillage and irregular grading.
Pro tip (2026): Local quarry prices for crusher run gravel range $35–$55 per ton depending on region. Use our tonnage output to request quotes confidently.
Exclusive Insight: Why Compaction Factor Matters More Than You Think
Many homeowners underestimate crush and run compaction. A typical mistake: ordering material based on compacted volume only. In reality, loose crusher run contains air voids that collapse under vibration. For every 1 cubic yard of compacted base, you need about 1.25 cubic yards of loose material. Our crusher run calculator automatically adjusts for this, saving you from costly re-orders. For 2026, advanced plate compactors achieve 92-95% density, so we use a factor of 1.25 for safety.
Example: 24x36 ft driveway, 5 inches compacted depth
Area = 864 sq ft · Compacted volume = (864 × 5) ÷ 324 = 13.33 cy · Loose volume = 13.33 × 1.25 = 16.66 cy · Tons = 16.66 × 1.4 = 23.3 tons. Add 10% waste → ~25.6 tons. Our calculator does this instantly.

Frequently Asked Questions (Crusher Run Calculator)
Crusher run (crush and run) is primarily used as a base material for driveways, patios, walkways, and under concrete slabs. It compacts into a hard, stable surface.
For a residential driveway, we recommend 4 to 6 inches of compacted crusher run. For light traffic, 4 inches is typical; for heavier vehicles, use 6 inches.
For a 10x20 ft driveway with 4 inches depth and standard compaction, you'll need approximately 3.1 to 3.5 tons. Use our calculator for exact numbers.
Yes, compaction is critical. Crusher run gravel must be compacted in layers using a plate compactor or roller. Without compaction, the surface will settle unevenly.
Crusher run contains stone dust and angular aggregates that bind together when compacted. #57 gravel is clean stone that drains well but does not lock into a solid base.
Yes, our calculator uses standard US aggregate density (1.4 tons per cubic yard) and updated compaction factors (1.25) reflecting 2026 regional practices.
Absolutely. A 4-6 inch compacted crusher run base provides excellent support for concrete slabs, preventing cracking due to soil movement.
