A cubic yard is a volume of 27 cubic feet. To find the cubic yards in a space you need its shape and depth. Choose the shape that fits your area from the list below, enter the measurements, and the calculator does the math.
Each shape page includes the formula, a worked example, a table of sizes, and answers to common questions. If your area has an odd outline, try the irregular calculator or split it into simple shapes and add them up.

Frequently asked questions
Which calculator should I use?
Use the shape that matches your area. For a bed, slab, or pad, the rectangle calculator is usually right. For a round area, use the circle calculator.
Does the calculator work on a phone?
Yes. The tools are built for small screens and work in any modern browser.
What if my area is not a regular shape?
Use the irregular calculator with the total area and an average depth, or break the area into rectangles and add the results.
