Calculate pavers needed for patios, driveways, and walkways with pattern-specific waste factors.
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.
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.
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.
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.
Enable bedding sand calculation if you need to order sand for the paver base. Standard depth is 25mm with 15% extra for compaction.
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.
| Pattern | Waste | Difficulty | Best For |
|---|---|---|---|
| Stack Bond | 5% | Easy | Small areas |
| Running Bond | 7% | Easy | Patios, paths |
| Basket Weave | 7% | Medium | Patios |
| Herringbone 90 | 11% | Medium | Patios, driveways |
| Herringbone 45 | 18% | Hard | Driveways (best interlock) |
