Planning guide
What is paver base?
A paver base is a compacted layer of graded aggregate that spreads loads, supports drainage, and limits settlement under segmental paving.
How this calculation works
The tool calculates base volume from paved dimensions and compacted depth. The optional material allowance helps cover small measurement differences, handling losses, and minor site variation.

Choose an input for your project
Enter finished compacted aggregate depth, not total excavation or loose pile depth.
| Application | Early planning range | What can increase it |
|---|---|---|
| Pedestrian patio or walk | Often 4–6 compacted in | Weak soil, drainage, frost |
| Residential driveway | Project-specific | Vehicle loads, soil, drainage, and freeze-thaw conditions |
| Bedding layer | Usually estimated separately | Follow the paving-system specification |
Include the base extension beyond the visible paver edge when measuring area.
Common measurement mistakes
- Calculating pavers but not the base
- Compacting one thick lift
- Using a uniform round stone that will not lock
Planning tips
- Extend the base beyond the paver edge
- Compact in thin lifts
- Plan drainage so water does not collect against buildings
Paver Base Calculator FAQs
What paver base depth should I use?
Base depth varies with climate, soil, and traffic. Pedestrian patios often need 4–6 compacted inches (10–15 cm); driveways generally need more.
Should I enter loose or compacted paver base depth?
Enter the required finished compacted depth. Because loose aggregate consolidates during compaction, confirm with the supplier how much loose material is needed to achieve that finished depth.
How should paver base be compacted?
Place and compact the aggregate in thin lifts rather than one thick layer. Follow the paver manufacturer's requirements for lift thickness, moisture, and compaction equipment.
