For irregular shapes, divide into rectangular sections and calculate separately.
Always add 5-10% extra to account for compaction and settling.
Remember: 1 cubic yard = 27 cubic feet.
The total cubic yards of material needed for your project
Use our Cubic Yards Calculator to quickly determine the volume of materials such as soil, gravel, concrete, mulch, or any bulk substance in cubic yards.
Picture a box that’s three feet tall, three feet wide, and three feet deep. That’s a cubic yard. It’s 27 cubic feet jammed together (3 × 3 × 3). You’ll hear this term tossed around a lot if you’re messing with landscaping, construction, or buying stuff like mulch or gravel in bulk.
If you’re using feet:
(Length × Width × Depth) ÷ 27
If you’re stuck with inches:
(Length × Width × Depth) ÷ 46,656
