Calculate cubic yards, tons, and cost of pea gravel for paths, playgrounds, and landscaping.
Pea gravel density: 1.3 tons per cubic yard
| Use | Recommended Depth | Notes |
|---|---|---|
| Decorative border | 1–2 inches | Mainly for looks, minimal function |
| Garden path | 2–3 inches | Use landscape fabric underneath |
| Pet area / dog run | 3–4 inches | Easier on paws than crushed stone |
| Driveway (not recommended) | 4+ inches | Pea gravel shifts; use crushed stone for driveways |
| Playground safety surface | 9–12 inches | CPSC standard for equipment up to 8 ft high |
Volume (cu ft) = Length × Width × Depth (inches ÷ 12). Divide by 27 to get cubic yards. Example: 10×10 ft at 2" deep = 0.62 cubic yards ≈ 0.8 tons.
About 100 sq ft at 2" deep, or 50 sq ft at 4" deep. 1 cubic yard of pea gravel weighs approximately 1.3 tons.
Yes — pea gravel migrates easily. Install plastic, metal, or wood edging to keep it in place.
Not ideal. Pea gravel is round and doesn't compact, so cars push it aside. Use crushed limestone or #57 stone for driveways. If you do use pea gravel, use edging and a solid base.
