Calculate Gravel Volume & Weight for Driveways, Landscaping & Construction Projects

📏 Pro Tips for Accurate Gravel Calculations: Measure area carefully in consistent units. Standard depth: 2-6 inches depending on application. Account for gravel density (affects weight). Add 5-10% for compaction and settling. For irregular areas, break into simple shapes. Consider traffic loads and maintenance frequency.

Basic Gravel Calculator

Formula:
Volume (cubic yards) = Area (sq ft) × Depth (inches) ÷ 324
Weight (tons) = Volume (cubic yards) × Density (tons per cubic yard)
Total Cost = Weight × Price per unit

Example: 500 sq ft × 3 inches ÷ 324 = 4.6 cubic yards × 1.5 = 6.9 tons

🔨 Gravel Applications & Depth Guidelines
Driveway Installation:
  • Total depth: 4-6 inches (10-15 cm)
  • Base layer: 2-3 inches crushed stone (compacted)
  • Top layer: 1-2 inches smaller gravel or pea gravel
  • Maintenance: Rake annually, add top-up layer every 2-3 years
  • Best material: Crushed limestone or crushed granite
Landscaping & Decorative:
  • Typical depth: 2-4 inches (5-10 cm)
  • Use landscape fabric: Prevents weeds, extends life
  • Best materials: Pea gravel, marble chips, river rock
  • Maintenance: Rake every season, refresh annually
  • Around plants: Keep 2-3 inches from plant stems
Drainage & Foundation:
  • Typical depth: 4-8 inches (10-20 cm)
  • Best materials: Bank gravel, crushed stone, pea gravel
  • Purpose: Water management, foundation protection
  • Compaction: Compact layers every 2-3 inches
  • Lifespan: 5-10+ years if properly installed
Pathways & Walkways:
  • Typical depth: 2-3 inches (5-7.5 cm)
  • Best materials: Pea gravel, crushed stone, marble chips
  • Edging: Use borders to contain gravel
  • Maintenance: Rake monthly, refresh yearly
  • Comfort: Smaller, smoother gravels more comfortable
💰 Gravel Project Cost Analysis
Price Breakdown Example (500 sq ft, 3 inches deep):

Volume: 4.6 cubic yards
• Standard gravel: 4.6 × $25 = $115 material
• Crushed stone: 4.6 × $20 = $92 material
• Pea gravel: 4.6 × $35 = $161 material
• River rock: 4.6 × $45 = $207 material
• Delivery (typical): +$75-150
• Landscape fabric (optional): +$25-50

Budget Factors:
  • Material cost: Largest expense, varies by type and location
  • Delivery: Add $75-200 for most projects
  • Site preparation: Remove existing material (labor cost)
  • Compaction equipment: Rent or hire for larger projects
  • Landscape fabric: $25-50 additional
  • Annual maintenance: Budget $20-50/year for touch-ups
Ways to Save:
  • Buy bulk quantities for better pricing
  • Order in off-season (spring/fall vs summer)
  • Mix materials: expensive top layer, cheaper base
  • DIY installation saves 50-70% on labor
  • Use landscape fabric to extend gravel life
  • Recycle or reuse existing gravel when possible
❓ Frequently Asked Questions
How often should I add new gravel? +
Typical maintenance: annually for high-traffic areas. Add 1-2 inches top-up in spring. For low-traffic decorative areas: every 2-3 years. Complete replacement: 3-5 years depending on type and maintenance. Regular raking extends lifespan.
Is landscape fabric necessary under gravel? +
Highly recommended. Benefits: prevents weeds (75% reduction), stops soil mixing, extends gravel life. Cost: minimal ($25-50 for average project). Use quality fabric rated for 5+ years. Install before spreading gravel for best results.
What's the best gravel for a driveway? +
Best choice: crushed limestone or crushed granite (angular shape, compacts well). Size: 1-2 inches for strength. Layering: 2-3 inches base + 1-2 inches top. Avoid smooth pea gravel (rolls under tires). Total depth: 4-6 inches.
How do I calculate gravel weight for ordering? +
Weight = Volume × Density. Standard gravel: 1.5 tons per cubic yard. Formula: volume (cubic yards) × 1.5 = tons needed. Example: 5 cubic yards × 1.5 = 7.5 tons. Different materials have different densities (check label).
Should I compact gravel after spreading? +
Yes, especially for driveways and paths. Compaction increases stability, reduces settling, improves drainage. Manual (light): rake and walk multiple times. Professional: use plate compactor or vibratory compactor for best results. Compact base layer most thoroughly.
Can pea gravel be used on driveways? +
Not recommended as primary surface. Too smooth, rolls under tires, doesn't compact well. Can be used as decorative top layer (1 inch max) over crushed stone base. Better for: playgrounds, pathways, decorative areas where comfort matters more than stability.
How much does gravel weigh per cubic yard? +
Varies by type: Standard gravel 1.5 tons. Crushed stone: 1.3-1.6 tons. Pea gravel: 1.3 tons. River rock: 1.5-1.6 tons. Marble chips: 1.4 tons. Weight affects: delivery costs, equipment needed, compaction requirements. Heavier materials compact better.
What's the difference between gravel and crushed stone? +
Gravel: naturally occurring, rounded stones from erosion, 0.2-2 inches. Crushed stone: mechanically broken, angular edges, compacts better. Crushed stone more suitable for driveways (angular shape locks together). Gravel better for decorative or drainage. Different densities and costs.
