A yard of pea gravel weighs approximately 2,500 to 2,800 pounds (1.25 to 1.4 tons).
Pea gravel weight per cubic yard varies based on moisture content, stone density, and size (typically 3/8"). Dry pea gravel averages 2,600 lbs (1.3 tons), while wet gravel can reach 3,000 lbs. Always confirm with your supplier for precise measurements, as weight impacts delivery costs and project planning.
Key Factors Affecting Pea Gravel Weight
- Moisture: Wet gravel adds 10-15% more weight.
- Stone size: Smaller pebbles (1/4") pack tighter, increasing density.
- Material type: Limestone (~2,400 lbs) vs. granite (~2,800 lbs).
- Compaction: Loose gravel weighs less than compacted layers.
Weight Comparison: Pea Gravel vs. Other Aggregates
| Material | Weight per Cubic Yard (lbs) | Weight per Cubic Yard (tons) | Best For |
|---|---|---|---|
| Pea Gravel (dry) | 2,500-2,800 | 1.25-1.4 | Pathways, drainage, landscaping |
| Crushed Stone | 2,700-3,000 | 1.35-1.5 | Driveways, structural fill |
| Sand (dry) | 2,700-3,000 | 1.35-1.5 | Masonry, leveling bases |
| River Rock (1-3") | 2,400-2,600 | 1.2-1.3 | Decorative borders, water features |
How to Calculate Pea Gravel Weight for Your Project
- Measure volume: Length (ft) × Width (ft) × Depth (ft) ÷ 27 = cubic yards.
- Estimate weight: Cubic yards × 2,600 lbs (average dry weight).
- Adjust for moisture: Add 10% if gravel is wet.
- Check supplier specs: Request a "proctor test" report for exact density.
Common Pea Gravel Quantities & Weights
- ½ yard: ~1,300 lbs (0.65 tons) - Small pathways or garden accents.
- 1 yard: ~2,600 lbs (1.3 tons) - Covers ~100 sq ft at 3" depth.
- 5 yards: ~13,000 lbs (6.5 tons) - Full driveway or large patio base.
- 10+ yards: Bulk delivery (20,000+ lbs) - Commercial projects or extensive landscaping.
Tips for Handling Pea Gravel Weight
- Delivery: Confirm truck capacity (e.g., dump trucks hold 10-14 yards).
- Storage: Spread gravel on a tarp to prevent moisture absorption.
- Safety: Use a wheelbarrow (max 600 lbs capacity) for transport.
- Compaction: Rent a plate compactor for stable surfaces (adds ~5% weight).
