Materials for a 20×24 paver patio
| Item | Quantity | Notes |
|---|---|---|
| Paved area | 480 sq ft | length × width |
| Pavers to order | 514 sq ft | 7% extra for cuts and breakage (1,371 pieces if you use a 6 × 9 in paver) |
| Base: crushed stone (2A modified / crusher run) | 14.9 tons | 6 in compacted in 2–3 in lifts |
| Bedding sand (concrete sand) | 2.4 tons | 1 in, screeded, never compacted before the pavers go down |
| Polymeric joint sand | 8 bags (50 lb) | about 60 sq ft per bag on standard joints |
| Edge restraint | 68 ft | three open sides, spiked every 12 in |
| Filter fabric under the base | 552 sq ft | keeps the base out of the soil |
| Soil dug out | 18.1 cu yd | about 9 in deep, plus room for the base to extend 6 in past the pavers |
Quantities use common rules: crushed stone at about 1.4 tons per cubic yard plus 20% for compaction, concrete sand at about 1.35 tons per cubic yard. Your stone yard can convert to their product. Base depths assume normal soil in a freeze-thaw climate; soft or wet soil needs more.
Good to know
- A 20×24 is room for dining, lounging and a fire pit, which is when it pays to plan it as zones instead of one slab.
- When a paver job fails, it is almost always the base, not the pavers. The stone in the list above is the part not to skimp on.

How much does a 20×24 paver patio cost installed?
We build a 20×24 paver patio in central Pennsylvania for about $21,700 ($45 per sq ft), including excavation, base, materials and cleanup. Prices elsewhere depend on local labor and stone, so the reliable way to price it where you live is a scaled plan and two or three local bids on the same plan.
