Gravel Calculator

Multiply length × width × depth to get the volume, then convert to cubic yards (divide cubic feet by 27). For a 20 × 10 ft area at 3 inches deep: 20 × 10 × 0.25 = 50 cubic feet ÷ 27 = about 1.85 cubic yards.

Most gravel weighs about 1.4 tons (roughly 2,800 lb) per cubic yard, though it ranges from about 1.4 to 1.7 depending on the stone and moisture. This calculator defaults to 1.4 tons/cu yd and lets you change it.

For a walkway or décor, 2–3 inches is typical. For a driveway, use 4–6 inches, often in layers over a compacted base. Deeper layers need proportionally more material — adjust the depth field to compare.

Yes — add about 5–10% for compaction, uneven ground, and spillage. Use the waste field to include it. It is usually cheaper to order slightly more than to pay for a second small delivery.

At 2 inches deep, one ton of gravel covers roughly 100 square feet; at 3 inches, about 70 square feet. Coverage drops as depth increases, so always calculate by volume for the depth you actually need.
