Paver Calculator
Everything to order for a paver patio, walkway or driveway: pavers by size and pattern, compacted base gravel, bedding sand, polymeric joint sand and edge restraint, for any shape.
Pavers = area (sq ft) ÷ one paver's area (sq ft), plus 5% (10–15% for herringbone or diagonal). 4 × 8 in pavers need 4.5 per sq ft; 6 × 9 in need 2.67; 12 × 12 in need 1. A 12 × 12 ft patio takes 404 pavers of 6 × 9 in, about 3.7 tons of base at 4 in and 24 bags of bedding sand.
Pavers per square foot by size
| Paver | Per sq ft | Per 100 sq ft (+5%) |
|---|---|---|
| 4 × 8 in (holland / brick) | 4.50 | 473 |
| 6 × 6 in | 4.00 | 420 |
| 6 × 9 in | 2.67 | 281 |
| 12 × 12 in | 1.00 | 105 |
| 16 × 16 in | 0.56 | 60 |
| 24 × 24 in | 0.25 | 27 |
Waste allowance by pattern
| Pattern | Extra to order | Why |
|---|---|---|
| Running bond or stack | 5% | Cuts only at the ends of rows |
| Herringbone | 10% | More cuts along the borders |
| Diagonal (45°) | 15% | Every edge paver is cut at an angle |
Frequently asked questions
How many pavers do I need?
Divide your patio area in square feet by the area of one paver in square feet (length × width in inches ÷ 144), then add 5% for cuts, or 10–15% for herringbone or diagonal patterns.
How many pavers per square foot?
4.5 for 4 × 8 in brick pavers, 4 for 6 × 6 in, 2.67 for 6 × 9 in, 1 for 12 × 12 in, 0.56 for 16 × 16 in and 0.25 for 24 × 24 in.
How much base do I need under pavers?
About 4 in of compacted crushed stone for patios and walkways on firm soil, 6 in on clay or in cold climates, and 8–12 in for driveways, with 1 in of sand on top. See the paver base calculator for tons.
How much polymeric sand do I need?
A 50 lb bag typically fills the joints of about 30–80 sq ft, depending on joint width and paver size: narrow joints between large pavers use far less than wide joints between tumbled bricks.
How much do pavers cost for a 12 × 12 patio?
Enter your local paver and material prices in the calculator. Materials for 144 sq ft are usually a few hundred dollars; professional installation adds labor for excavation, base compaction and cutting.

Base and sand depths follow interlocking concrete paver practice published by the Concrete Masonry and Hardscapes Association (formerly ICPI): 4–6 in of compacted aggregate for patios and walkways, 8–12 in for driveways, 1 in of screeded bedding sand. The base extends 6 in past the edges and adds 20% for compaction; base gravel is 1.5 tons per cu yd. Polymeric sand coverage varies with joint width and paver shape; read your bag.
