Concrete Volume Calculators

Every concrete estimate starts with volume: length × width × depth, converted to the cubic yards that ready-mix is sold in and the bag counts that bagged mix is sold in. The volume calculators here handle any rectangular pour and accept each dimension in feet, inches, yards, meters or centimeters.

If your project is a named shape — a patio slab, a footing, a wall — the dedicated calculators below pre-fill the sensible thicknesses and add the allowances that shape needs.
