How It Works

  1. 1. Enter the total area

    Calculate your patio, driveway, or walkway area in square meters. For rectangular areas, multiply length by width. For irregular shapes, divide into rectangles and add together.

  2. 2. Enter your paver dimensions

    Enter the length and width of your pavers in millimeters. Use the common size buttons for standard sizes (200x100mm, 300x300mm, 400x400mm, 450x300mm) or enter custom dimensions.

  3. 3. Specify joint spacing

    Enter the gap between pavers (3-5mm is typical). Larger joints mean fewer pavers needed, but require more joint filler. Joints wider than 10mm may need polymeric sand.

  4. 4. Select your laying pattern

    Choose your pattern based on aesthetics and structural needs. Herringbone is strongest for driveways. Running bond is easiest to lay. The calculator automatically adjusts waste percentage based on pattern complexity.

  5. 5. Toggle bedding sand calculation

    Enable bedding sand calculation if you need to order sand for the paver base. Standard depth is 25mm with 15% extra for compaction.

  6. 6. Order the displayed quantity

    The result includes waste for cuts and breakage. Order this exact quantity to ensure you have enough pavers to complete the project, plus spare matching pavers for future repairs.
