Quick answer
Calculate paver area first, then calculate the base and bedding layers separately. Depth must be converted to feet before volume calculation, and the required base depends on soil, drainage, climate and intended load.
Step by step
- Measure paver area Split patios, paths and borders into sections.
- Set base depth Use project-specific guidance for soil and traffic.
- Calculate each layer Area × depth gives cubic feet for base and bedding.
- Add pavers and edging Apply layout waste to pavers and keep edging hardware separate.
Formula or rule of thumb
Example
A 240 ft² patio with a 6 in base needs 120 ft³, or 4.44 yd³ of base material before compaction allowance.
Common mistakes
Using paver thickness as base depth, ignoring compaction, and assuming decorative walkway specifications apply to vehicle areas.
Planning note: product yields, installation methods, site conditions and local requirements can change the final quantity. Use the exact manufacturer or supplier information before purchasing.
Decision guide
| Decision point | What the estimate tells you | What to verify |
|---|---|---|
| Measurements | Start with accurate project dimensions and the correct units. | Replace generic assumptions with site measurements. |
| Product data | Use the actual package yield, coverage or density. | Check the current manufacturer or supplier label. |
| Final decision | Treat the result as an early planning estimate. | Confirm final quantities and requirements before purchase. |

FAQ
Does the base need compaction?
Most paver systems require proper compaction; follow the system specifications.
Is bedding sand the same as base aggregate?
No. They serve different functions and use different depths.
Can this design a driveway?
It estimates volume only; driveway base design needs site and load guidance.
