Type in your patio size and paver size and get the full shopping list — pavers with a waste allowance for your pattern, the gravel base and bedding sand underneath, and edging, with the total cost. No sign-up. The working is shown under every number.
Quick example: a 12 × 10 ft patio with 12 × 12 in pavers needs 132 pavers, 1.5 cubic yards of base gravel, 0.5 cubic yards of bedding sand and 6 lengths of edging — $499.50 at the example prices.
| Item | Buy | Cost |
|---|---|---|
| Estimated total | $0.00 |
Base gravel and sand are rounded up to the nearest 0.5 cubic yard, the smallest amount most suppliers will deliver. Joint (polymeric) sand for between the pavers is not included — allow roughly one 50 lb bag per 30 sq ft.
Estimate only — not a guarantee. Mistakes are possible, so always check the quantities with your supplier or a builder before you buy or build.
With 12 × 12 in pavers, each paver covers exactly 1 sq ft, so a 12 × 10 ft patio (120 sq ft) needs 120 pavers, and this calculator's shopping list shows 132 because it adds the 10% waste allowance for cuts and breakages.
A 4 × 8 in paver covers 0.22 sq ft, so a 16 × 16 ft patio (256 sq ft) needs 1,152 pavers before waste, and 1,268 with the standard 10% waste allowance — at the example price of $0.65 per brick paver that is $824.20 for the pavers.
This calculator allows a 4 in compacted gravel base: the patio area × 4 in of depth, converted to cubic yards. A 12 × 10 ft patio needs 1.48 cubic yards, which it rounds up to a 1.5 cubic yard order — about 2.1 tons at 1.4 tons per cubic yard.
Bedding sand goes down as a 1 in layer over the gravel base. A 12 × 10 ft patio needs 0.37 cubic yards, rounded up to a 0.5 cubic yard order in the shopping list.
This calculator sets the waste allowance by pattern: 10% for a straight pattern, 15% for diagonal and 20% for herringbone, because angled patterns cut the ends off more pavers. You can change the percentage in the calculator.
| Patio size | Pavers | Base gravel | Bedding sand | Edging (8 ft) | Total |
|---|---|---|---|---|---|
| 10 × 10 ft | 110 | 1.5 cu yd | 0.5 cu yd | 5 | $432.50 |
| 12 × 10 ft | 132 | 1.5 cu yd | 0.5 cu yd | 6 | $499.50 |
| 12 × 12 ft | 159 | 2.0 cu yd | 0.5 cu yd | 6 | $592.00 |
| 16 × 16 ft | 282 | 3.5 cu yd | 1.0 cu yd | 8 | $1,021.00 |
Paver counts include the 10% waste allowance for a straight pattern. Base gravel is a 4 in compacted layer and bedding sand a 1 in layer, each rounded up to the nearest 0.5 cubic yard for ordering. Totals use the example prices in the calculator above.
