Concrete Wall Volume Calculator
Enter the finished concrete dimensions of a solid, uniform wall. Use the number field for identical wall sections only.
How the calculation works
Volume in cubic feet = length in feet × height in feet × (thickness in inches ÷ 12) × count. Divide by 27 for cubic yards and add the selected waste percentage.
Worked example
One wall 20 ft long, 4 ft high and 6 in thick has 40 ft³ of concrete, or 1.48 yd³. With 10% extra, the order estimate is 1.63 yd³ or 74 bags at 0.60 ft³ each.
Before you order
Openings, pilasters, footings and block cores are not subtracted. Form pressure, reinforcement and wall thickness require project-specific engineering; this tool only estimates solid volume.
Review the calculation method and source notes, then use the supplier checklist before placing an order.
