How it's worked out
- Area: 16 × 16 = 256 sq ft
- Pavers: 256 × 4.5 pavers per sq ft = 1,152, plus 10% = 1268
- Base: 256 × 4 in ÷ 12 ÷ 27 × 1.15 for compaction = 3.63 yd³ ≈ 5.1 tons
- Sand: 256 × 1 in ÷ 12 = 21.3 cu ft = 43 bags
16x16 patio with other paver sizes
| Paver size | Pavers with 10% extra |
|---|---|
| 4 × 8 in | 1268 |
| 6 × 6 in | 1127 |
| 6 × 9 in | 751 |
| 12 × 12 in | 282 |
| 16 × 16 in | 159 |
| 12 × 24 in | 141 |
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.
