How Much Paver Base Do I Need?
Estimate paver base stone and bedding sand before building a patio or walkway.
Last reviewed: June 2026
Short Answer
Paver base volume = area x base depth in feet. Bedding sand is calculated separately, often around 1 inch deep. Convert cubic feet to cubic yards by dividing by 27, then estimate tons using material density.

Paver projects usually need a compacted crushed stone base and a separate bedding sand layer. Base depth depends on traffic, soil, drainage, and climate.
This guide is useful for homeowners planning patios and for hardscape crews checking material quantities before ordering.
Simple Formula
Base cubic feet = area x base depth in feet. Sand cubic feet = area x sand depth in feet. Cubic yards = cubic feet / 27.
Example: 200 square foot patio
- Base depth: 4 inches / 12 = 0.333 ft
- Base volume: 200 x 0.333 = about 66.7 cubic feet
- Base yards: 66.7 / 27 = about 2.47 cubic yards
- Sand depth: 1 inch / 12 = 0.083 ft
- Sand volume: 200 x 0.083 = about 16.7 cubic feet
Plan for about 2.5 cubic yards of base plus about 0.6 cubic yards of bedding sand before waste and compaction.
Common Mistakes
- Skipping compacted base stone.
- Using too much bedding sand.
- Forgetting that base material compacts.
- Not adjusting depth for driveway loads, poor soil, or freeze-thaw conditions.
FAQ
How deep should paver base be?
Patios and walkways often need several inches of compacted base. Driveways or poor soils may require more depth.
Do I calculate bedding sand separately?
Yes. Base stone and bedding sand are different layers and should be estimated separately.
