Paver Calculator

How to Calculate Pavers

Paver estimation is straightforward: divide your project area by the face area of one paver, then add waste. The complication is the base materials — every paver installation needs a compacted gravel base and a leveling sand layer, and those volumes depend on the project area and standard depth requirements.

Common Paver Sizes

• 4 × 8 inches — Classic brick paver. 4.5 per sq ft. Most versatile for patterns.
• 6 × 6 inches — Square cobble. 4 per sq ft.
• 6 × 9 inches — Rectangle. 2.67 per sq ft.
• 12 × 12 inches — Large format. 1 per sq ft. Fastest to install.
• 16 × 16 inches — Extra large. 0.56 per sq ft. Needs thicker base for stability.

The Base Layer Matters Most

A paver patio is only as good as its base. The ICPI (Interlocking Concrete Pavement Institute) recommends 6 inches of compacted crushed stone base for residential pedestrian applications and 8–12 inches for driveways. On top of the base goes 1 inch of leveling sand (concrete sand, not play sand), then the pavers, then polymeric sand in the joints. Use the Gravel Calculator and Sand Calculator for more detailed base material estimates.

The Bottom Line

Paver projects have three material categories: the pavers themselves, the base materials (gravel + sand), and the edge restraint + polymeric sand for finishing. This calculator handles all of them from your project dimensions. Order pavers from the same production lot for consistent color — returns of excess full pallets are usually accepted. And invest in the base: a properly compacted gravel-and-sand base prevents the two most common paver failures (settling and shifting) for decades.
