Cubic Yard Calculator
A cubic yard is 27 cubic feet, so multiply length × width × depth in feet and divide by 27. Enter your area and depth — depth is usually in inches — to get cubic yards and cost.
How to calculate cubic yards
Multiply length × width × depth, all in feet, then divide by 27. Depth is usually given in inches, so divide inches by 12 first — the calculator does this for you when you pick inches.
Common uses
Bulk landscaping and building materials are priced by the cubic yard:
- Gravel and crushed stone for driveways and paver bases
- Topsoil and compost for garden beds
- Mulch for landscape coverage
- Concrete and fill for slabs and footings
For the gravel and sand under a patio, the paver calculator returns those volumes directly.
Ordering tips
Suppliers deliver in whole or half cubic yards, so round up. A little extra is normal — material compacts and settles once placed.
