Turn any length, width and depth into cubic yards, the unit landscape and concrete suppliers sell by.
Depth in inches
Identical beds or spots
Tons per cubic yard. Ask your supplier for theirs.
Gravel needed
1.85 cu yd
50 cubic feet over 200 sq ft
Suppliers sell bulk material in whole or half yards. Round up: an extra half yard costs less than a second delivery.
Cubic yards = length (ft) × width (ft) × depth (ft) ÷ 27
For a circle, use 3.1416 × radius² instead of length × width. For a triangle, use base × height ÷ 2.
| Depth | Square feet per cubic yard |
|---|---|
| 1 in | 324 |
| 2 in | 162 |
| 3 in | 108 |
| 4 in | 81 |
| 6 in | 54 |
| 8 in | 41 |
| 12 in | 27 |
| 1 cubic yard | 27 cubic feet |
| 1 cubic yard | 0.7646 cubic meters |
| 1 cubic yard | 46,656 cubic inches |
| 1 cubic yard | 201.97 US gallons |
| 1 cubic meter | 1.308 cubic yards |
Multiply length × width × depth, all in feet, to get cubic feet, then divide by 27. If the depth is in inches, divide it by 12 first. Example: 10 ft × 10 ft × 4 in = 10 × 10 × 0.333 = 33.3 cu ft ÷ 27 = 1.23 cubic yards.
Exactly 27. A yard is 3 feet, so a cubic yard is 3 × 3 × 3 = 27 cubic feet. That is about 0.765 cubic meters.
It depends on the depth: 324 sq ft at 1 inch, 162 at 2 inches, 108 at 3 inches, 81 at 4 inches and 54 at 6 inches.
No. A yard measures volume and a ton measures weight. A yard of gravel weighs around 1.4 tons, a yard of topsoil around 1.1 tons, and a yard of mulch much less. Pick a material in the calculator to see the weight.
