Calculate cubic yards from length, width, and depth for concrete, gravel, soil, mulch, and more — plus the weight in tons and how much you need.
Pick a project, then adjust the dimensions, depth, and material to match yours.

Cubic yards are how bulk materials — concrete, gravel, soil, mulch, sand, and stone — are sold and delivered. To find how many you need, multiply the length, width, and depth of your area in feet and divide by 27 (one cubic yard is a 3 × 3 × 3 ft block, or 27 cubic feet). Because beds and driveways are usually measured in inches, this calculator lets you enter depth in inches or feet and converts automatically. Pick a material and it also shows the weight in tons — what you actually need to know for delivery and hauling — plus optional cost and a side-by-side weight comparison across materials. Leave the material on 'General' for a quick volume-only answer.
A cubic yard is a volume equal to a cube three feet on each side — 3 ft × 3 ft × 3 ft = 27 cubic feet. It's the standard unit for ordering bulk landscaping and construction materials. To convert your project to cubic yards, calculate the volume (length × width × depth, all in feet) and divide by 27; if your depth is in inches, divide it by 12 first, or use the shortcut (length × width × depth-in-inches) ÷ 324. One cubic yard covers about 324 square feet at 1 inch deep, 108 sq ft at 3 inches, or 81 sq ft at 4 inches. Weight varies a lot by material: a cubic yard of concrete weighs roughly 1.96 tons, gravel about 1.42 tons, sand 1.35 tons, topsoil around 1.2 tons, and bark mulch only about 0.25 tons — which is why knowing the tonnage matters for delivery and hauling.

Multiply length × width × depth in feet, then divide by 27. For example, a 20 × 10 ft area, 3 inches deep, is 20 × 10 × 0.25 = 50 cubic feet, or 50 ÷ 27 ≈ 1.85 cubic yards. If your depth is in inches, you can use the shortcut (length × width × depth-in-inches) ÷ 324.
It depends on the material. A cubic yard of concrete weighs about 1.96 tons, gravel about 1.42 tons, sand 1.35 tons, topsoil around 1.2 tons, and bark mulch only about 0.25 tons. Moisture adds weight. This calculator shows the tonnage for your material so you can plan delivery and hauling.
One cubic yard covers about 324 square feet at 1 inch deep, 162 sq ft at 2 inches, 108 sq ft at 3 inches, or 81 sq ft at 4 inches. The deeper the layer, the less area a yard covers — divide 324 by the depth in inches.
Yes. A cubic yard is a cube three feet on each side: 3 ft × 3 ft × 3 ft, which equals 27 cubic feet. That's why you divide cubic feet by 27 to get cubic yards.
You can't convert directly — you also need a depth. Multiply your area in square feet by the depth in feet to get cubic feet, then divide by 27. For a depth in inches, multiply the area by the depth in inches and divide by 324.
Calculate the area (length × width) and depth of your project, then divide the volume by 27. For example, a 30 × 10 ft gravel driveway at 4 inches deep needs about 3.7 cubic yards. Enter your numbers above and pick the material to also see the tonnage.
A standard dump truck typically holds about 10–14 cubic yards, while a pickup holds roughly 2–3 cubic yards (and far less by weight for heavy materials like gravel or concrete). Always check the truck's weight limit — that's why knowing the tonnage matters.
For most bulk-material projects, adding 5–10% is wise to cover uneven ground, settling, and spillage. This calculator lets you add an optional waste percentage so you order enough the first time.
