Enter your patio or walkway area dimensions and paver size with joint spacing. The calculator divides your total area by the per-paver footprint (including joints). Sand is estimated at approximately 1 ton per 500 square feet. Base material assumes a 4-inch depth of compacted gravel, converted to cubic yards. This calculator does not account for edge restraints, geotextile, or complex drainage setups.
Order 5–10% extra pavers. Account for cuts along edges, misaligned pieces, and future damage or replacement.
Most professionals recommend 4 inches of compacted gravel or crusher run for patios and light-traffic walkways. Check local codes and paver manufacturer specs for your climate.
Standard is 1/8 inch (0.125 in) to 1/4 inch (0.25 in) for most interlocking pavers. Wider joints are common in casual designs but use more sand.
Yes, but it limits drainage. Use a thin sand layer and ensure the concrete slopes slightly to shed water.
Polymeric sand hardens when wet and prevents weed growth. It uses the same volume as regular sand but costs more.
