Concrete Yard Calculators
"A yard of concrete" is a cubic yard: 27 cubic feet, 3 × 3 × 3 ft. Poured 4 inches thick it covers 81 ft² — most of a two-car driveway apron. The yard calculators here work the number both ways: how many yards your project takes, and how far the yards you're quoted will actually stretch.
Coverage is thickness-sensitive: the same yard that covers 81 ft² at 4 inches covers only 54 ft² at 6 inches. Run your real thickness, not a guess.
