Cubic Yard Calculator

Work out the cubic yards in a rectangular area from its length, width and depth — the unit bulk material is ordered in.

Computed in your browser — nothing you enter is uploaded. Figures are presented for United States against IRC 2024, and every formula is cited under regulatory standards below.

For the dimensions entered, expect a volume to order of 3.45 cubic yards. Note that length and width sit at the edge of the range this calculator was checked against, so treat the output as indicative rather than settled. Set for United States against IRC 2024. The market selector changes both the units and the code cited.

Estimated cost — your price

This site holds no price list for this material — local prices vary too much to publish honestly. Enter your supplier's price and the result is costed with it.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction. Spotted an arithmetic or standards error? Report it to contact@craftquantities.com with your inputs — confirmed fixes become pinned regression tests.

Frequently asked questions

How many cubic feet in a cubic yard?
Twenty-seven. A yard is three feet, and three cubed is twenty-seven. That is the conversion people get wrong most often — dividing by three instead of by twenty-seven under-orders by a factor of nine.
How do I enter a depth in inches?
Switch the unit toggle to imperial and enter inches directly. If you are converting by hand, divide by twelve: 4 in is 0.333 ft, 6 in is 0.5 ft. Rounding 4 in to 0.4 ft over-orders by 20%, which on a large pour is a wasted delivery.
Should I order the exact figure?
No. Bulk material is delivered in whole units and subgrade is never perfectly level, so the low spots absorb more than the average depth predicts. The waste allowance here covers that; on a rough excavation raise it rather than ordering twice.
Does this work for a circular or irregular area?
Not directly — this is length by width. For a circle, work out the area separately (π × radius²) and treat that as one side against a depth. For an irregular shape, split it into rectangles and add the results.
