Concrete quantity for a small equipment, shed or utility pad.
Pad length, width, thickness, thickened areas and waste.
Cubic volume and a rounded order estimate.
Base preparation, drainage, anchors, reinforcement and load requirements are not determined by volume alone.
See the estimated project quantity from your measurements.
Add waste and round to complete bags, boxes, cans, bundles or delivery quantities.
Review product coverage, site conditions, local requirements and supplier details before ordering.
Estimate concrete for a rectangular pad, equipment base, landing or small slab.
Cubic feet = length × width × thickness in feet. Cubic yards = cubic feet ÷ 27.
Planning note: Thickness, reinforcement, joints and subgrade must follow the project requirements.
Calculate concrete volume for a rectangular pad and convert it to cubic yards. Start with the actual dimensions or load values from the project, keep the units consistent, and change the default assumptions when the product label or supplier sheet gives you a more accurate value.
This page is for early material planning. The result can change with openings, layout, cuts, waste, product yield, density, packaging, access, installation method and site conditions. It does not replace structural design, permitted drawings, manufacturer instructions or a contractor quotation.
For a simple project, enter one measured section first and review the result. If the shape is irregular, split it into smaller sections, calculate each section, and add the quantities before applying whole-bag, box, bundle or delivery rounding.
