Paver & Patio Calculator: Stones, Gravel, Sand & Cost Estimate

Q: How much waste should I use?

Use 5–10% waste for straight patterns and 10–15% for diagonals/herringbone and complex borders.

Q: What joint width is typical?

3–6 mm (1/8–1/4 in) is common with polymeric sand. Follow manufacturer guidance.

Q: How do I estimate edging?

Use the perimeter output to order edge restraints and spikes/stakes with margin for cuts.

Q: Does pattern change the count?

Pattern mainly impacts waste %. Increase waste for herringbone/diagonals and borders.

Plan patios and paths like a pro. Enter area, paver size, joints, and base depths to get paver count, waste, gravel & sand volumes, edge length, and cost-in yd³/m³ with imperial/metric units.

Paver & Patio FAQ

How much waste should I use?

5–10% for straight patterns; 10–15% for herringbone/diagonals/complex borders.

What joint width is typical?

Polymeric sand joints commonly 3–6 mm (⅛–¼ in). Follow the paver manufacturer.

How deep should the base be?

Walkways: 3–4 in gravel + 1 in sand; driveways: 6–8 in gravel + 1 in sand (soil/drainage dependent).

How do I estimate edging?

The tool outputs perimeter length—order edge restraints + spikes accordingly.

Does pattern change the count?

Pattern affects waste more than net count; set a higher waste % for complex patterns.
