Gravel Calculator

Calculate: area (sq ft) × depth (inches) ÷ 324 = cubic yards. Then multiply by the density factor (1.2–1.5 tons per cu yd depending on type) to get tons. For example, 200 sq ft at 2 inches deep: 200 × 2 ÷ 324 = 1.23 cu yd × 1.4 = 1.73 tons. Order 10% extra.

Gravel costs $20–$75 per ton depending on type. Base gravel/road base is cheapest at $20–$40/ton. Crushed stone runs $30–$55/ton. Pea gravel $25–$50/ton. River rock is premium at $40–$75/ton. Delivery adds $50–$150 per load. Bulk is much cheaper than bags for large projects.

2 inches for walkways and light decorative cover. 3–4 inches for patios, driveways, and parking areas. 4–6 inches for French drains and drainage applications. 6–8 inches for driveway base layers. Each inch of depth adds roughly 50% more material.

Pea gravel: decorative paths and garden beds. Crushed stone: driveways and general landscaping (packs well). River rock: decorative, dry creek beds, drainage. Base gravel (crusher run): compactable sub-base for pavers and driveways. Decomposed granite: natural-look paths and patios.

It depends on the type: pea gravel is about 1.4 tons/cu yd, crushed stone 1.4 tons, base gravel 1.5 tons, river rock 1.35 tons, and decomposed granite 1.35 tons. The denser the material, the more it weighs per cubic yard.

At 2 inches deep, 1 ton of crushed stone covers roughly 100–120 sq ft. At 3 inches deep, about 70–80 sq ft. At 4 inches deep, about 50–60 sq ft. Coverage varies by gravel type and density.

Yes, always install landscape fabric ($0.10–$0.30/sq ft) under decorative gravel to prevent weed growth and stop gravel from sinking into the soil. For drainage applications, use a permeable geotextile fabric. Overlap seams by 6 inches.

Yes, gravel is one of the most DIY-friendly materials. You'll need: a rake, wheelbarrow, landscape fabric, edging, and a tamper/plate compactor for base gravel. Plan for delivery — gravel is heavy (1 ton per cubic yard). Budget 1–2 days for a typical driveway project.
