Pea Gravel Calculator
Calculate pea gravel by area and depth. Cubic yards, tons, and truckloads included.
Inputs
1/2-inch pea gravel stays in place slightly better on slopes and is a good pick for patios and dog runs.

How it's calculated
Area is derived from your shape inputs and converted to sq ft.
Depth is converted to feet; cubic feet = area × depth.
Cubic yards = cubic feet ÷ 27, then × (1 + waste %) × (1 + compaction %).
Estimated tons = cubic yards (with waste) × 1.4.
Truckloads = cubic yards (with waste) ÷ truck capacity.
Total cost = cubic yards (with waste) × price per cubic yard + delivery.
Professional guidance
When to use pea gravel
Paths, dog runs, playgrounds, patios, and fire pit surrounds. Comfortable underfoot, drains freely.
Recommended depth
2 inches for light-use paths, 3–4 inches for patios, 6 inches over subgrade for playgrounds.
Pro tip
Pea gravel migrates. Use steel or paver edging at least as tall as the gravel depth.
Common mistakes
Laying pea gravel directly on soil. Always compact a 4-inch road-base layer underneath.
Material assumptions
- Pea gravel density: about 1.4 tons per cubic yard.
- Typical size: ¼ inch to ½ inch, smooth and rounded.
- Path depth: 2–3 inches; patio depth: 3–4 inches over compacted base.
