Cubic Yards Calculator

Convert length, width, and depth measurements directly into cubic yards, for any bulk material.

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.

Running these inputs gives 3.14 cubic yards as the volume. 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. Currently reading for United States under IRC 2024 — pick a different market above and the figures re-cast accordingly.

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

Why is this different from the material-specific calculators like Mulch or Topsoil?
This is a pure geometry conversion with no material-specific waste factors or pricing built in — useful as a quick, generic cubic yardage check, while the material-specific calculators add waste allowances and cost estimates tailored to that material.
Why divide by 27 to get cubic yards?
1 cubic yard equals 3 ft x 3 ft x 3 ft = 27 cubic feet, so dividing a cubic-foot volume by 27 converts it to cubic yards.
Can this be used for excavation or fill dirt volumes too?
Yes — this works for any rectangular volume, including excavation cuts, fill volumes, or footings, not just surface material layers.
