How it's worked out
- Area: 12 × 16 = 192 sq ft
- Pavers: 192 × 4.5 pavers per sq ft = 864, plus 10% = 951
- Base: 192 × 4 in ÷ 12 ÷ 27 × 1.15 for compaction = 2.73 yd³ ≈ 3.8 tons
- Sand: 192 × 1 in ÷ 12 = 16 cu ft = 32 bags
12x16 patio with other paver sizes
| Paver size | Pavers with 10% extra |
|---|---|
| 4 × 8 in | 951 |
| 6 × 6 in | 845 |
| 6 × 9 in | 564 |
| 12 × 12 in | 212 |
| 16 × 16 in | 119 |
| 12 × 24 in | 106 |
Herringbone and curved designs waste more, so allow 15% for those. You'll also need polymeric joint sand and edge restraint around the sides that aren't against a wall.
