The calculation

Volume = net area × depth × (1 + extra ÷ 100). Weight = volume × supplier density.

  • Enter your supplier’s bulk density to show weight. Volume alone cannot determine tons.
  • 10% extra is included once. Confirm supplier minimums and delivery increments.

    Measure with a little context

    How to use this paver base calculator

    The aggregate base is separate from bedding sand. Estimate each layer with its own thickness and product specification.

    Required depth depends on soil, drainage and traffic. Use the paving-system guidance rather than treating the example depth as a design.

    Volume = net area × depth × (1 + extra ÷ 100). Weight = volume × supplier density.

    A worked example

    With the example values shown below, the calculated result is 1.304 cu yd. These are demonstration inputs, not installation specifications.

    View the example measurements
    • Length / circle diameter: 12 ft
    • Width: 8 ft
    • Material depth: 4 in
    • Extra allowance: 10 %
    • Volume per bag: 0.5 cu ft

    From estimate to order

    Whole packages and pieces round up; measured lengths, areas and volumes keep full precision during calculation. Match the product dimensions and units to your quote, and check cuts, minimum orders and delivery before purchasing.

    Paver base planning questions

    How deep should I enter the paver base?

    Use the base thickness specified for the soil, drainage and expected traffic of your paving system. This calculator estimates the volume at that depth; it does not determine the required depth or substitute for installation guidance.

    Is paver base the same as the sand bed?

    No. Aggregate base and bedding sand are separate layers, with different thicknesses and products. Calculate them individually. If your dimensions describe the compacted base, confirm the ordering conversion for loose material with the supplier.
