Regular rectangular layout approximation; edge joints and cuts vary. Base depth is your input, not a load or drainage recommendation. Loose-to-compacted conversion is excluded.

Your calculation, step by step

No black boxes
  1. Nominal module area = (8 + 0.125) × (4 + 0.125) square inches.
  2. Count = ceil(200 × 144 / module area × waste factor).
  3. Base and sand are separate compacted geometric volumes.

What if things were different?

Save up to three scenarios, then change your inputs to compare the possibilities.

How to use this calculator

  1. Enter your own values in the labeled fields. Check the units and assumptions before comparing results. Only the fields needed for your selected calculation mode are shown.
  2. Your answer updates automatically. Review the calculation steps to see exactly how it was calculated.
  3. Copy, share, save, or download your result. Saved inputs stay on this device.

How the calculation works

Pavers≈ceil(area / jointed module area × allowance); layer volume=area × depth

The paver module includes one joint in each dimension as a repeating-layout approximation. Base and sand volumes are shown separately before loose-material bulking. Entered layer depths are assumptions, not site-specific drainage or load guidance. Review the units, period and assumptions before comparing scenarios. Displayed values are rounded, while the underlying calculation retains its available precision.

A worked example

A 100 ft² area with 12 × 12 inch pavers, no joints and no allowance needs 100 pavers. A 3-inch layer beneath it contains 25 ft³.

Reading your result

Use the main result together with its units and supporting figures. Display values are rounded; calculations keep their underlying precision. A change in inputs or assumptions can change the answer. Compare the step-by-step working with your intended use before relying on an estimate.
