Cubic Yards Calculator
Estimate cubic yards from length, width and depth.
How to Use the Cubic Yards Calculator
Enter length, width and depth to estimate volume in cubic yards.
Practical Example
A 12 ft by 9 ft area filled 0.5 ft deep contains 54 ft³, which equals 2 cubic yards.
Factors That Affect the Result
Compaction, uneven depth, irregular shapes, material settling and measurement accuracy can change the amount you need to order.
Frequently Asked Questions
How many cubic feet are in a cubic yard?
There are 27 cubic feet in one cubic yard.
Should I add extra material?
Often yes, especially for compacted or irregular projects.
Can I use this for gravel or soil?
Yes. Use the project dimensions and planned depth.

Working with Cubic Yards
Cubic yards are commonly used for concrete, soil, gravel and landscaping material. Convert dimensions to yards before multiplying, or calculate cubic feet first and divide by 27. A cubic yard is a volume, so area measurements alone are not enough; depth must also be included.
Actual material orders often need an allowance for compaction, settling, spillage or uneven excavation. Use the geometric result as the base quantity, then apply the supplier or project-specific waste factor instead of assuming the calculated volume is the exact purchase amount.
