Coverage & waste
Material profile
For a 16 ft × 12 ft patio (192 sq ft) with no openings, you need 211.2 sq ft of net paver coverage after a 10% waste allowance. Using 12×12in square paver at 1.0 sq ft each, that comes to 212 pavers, plus 5 bags of paver base sand — about $734.00 total at $3.25 per paver and $9 per bag.
How many patio pavers do common patio sizes need?
These figures use 12×12in square paver (1.0 sq ft each) and a 10% waste allowance.
| Patio size | Openings | Pavers needed | Sand bags |
|---|---|---|---|
| 10 ft × 10 ft | 0 sq ft | 111 pavers | 3 bags |
| 14 ft × 12 ft | 0 sq ft | 185 pavers | 4 bags |
| 16 ft × 14 ft | 20 sq ft | 225 pavers | 5 bags |
| 20 ft × 16 ft | 0 sq ft | 352 pavers | 8 bags |
| 24 ft × 18 ft | 30 sq ft | 463 pavers | 10 bags |
| 30 ft × 20 ft | 0 sq ft | 660 pavers | 14 bags |
Patio paver sizes and coverage per unit
| Type | Coverage / unit | Size | Best for |
|---|---|---|---|
| 12 x 12in square paver | 1.0 sq ft | 12 x 12in | Simple square-lay patios |
| 16 x 24in rectangular paver | 2.67 sq ft | 16 x 24in | Large-format modern patios |
| Cobblestone paver (6 x 6in) | 0.25 sq ft | 6 x 6in | Old-world style patios |
How to calculate how many patio pavers you need
- Measure the patio area Multiply length by width in feet to get gross patio area.
- Subtract openings Deduct the square footage of fire pits, planters, or steps that won’t be paved.
- Add your waste allowance Multiply net area by 1 plus your waste percentage (10% is typical) to cover cuts around edges and borders.
- Divide by coverage per paver Divide by the coverage of your chosen paver — 1.0 sq ft for 12×12in square, 2.67 sq ft for 16×24in large-format, 0.25 sq ft for cobblestone — and round up.
- Calculate paver base sand bags Divide the paver count by roughly 50 pavers per bag of bedding sand and round up.
Worked example
Here’s the math for a 16 ft × 12 ft patio with no openings using 12×12in square paver.
- Patio length × width16 ft × 12 ft = 192 sq ft
- Openings deducted0 sq ft
- Net paver area192 sq ft
- Area with 10% waste211.2 sq ft
- Pavers needed (1.0 sq ft each, 12×12in)212 pavers
- Sand bags (1 per 50 pavers)5 bags
- Estimated material cost212 × $3.25 + 5 × $9 = $734.00
Typical patio sizes and paver quantities
| Project | Net area | Quantity needed |
|---|---|---|
| Small entry patio (8×8 ft) | 64 sq ft | 71 pavers |
| Standard backyard patio (14×12 ft) | 168 sq ft | 185 pavers |
| Dining patio (16×16 ft) | 256 sq ft | 282 pavers |
| Large family patio (20×20 ft) | 400 sq ft | 441 pavers |
| Poolside lounge patio (24×18 ft) | 432 sq ft | 476 pavers |
Ordering patio pavers by the pallet
Patio pavers typically ship on pallets of around 100–140 units for 12×12in square paver, fewer for large-format sizes, and considerably more for small cobblestone units. Order from the same production run when possible — concrete and clay paver color can shift between batches, and a mismatched patio field is hard to hide. Add extra pavers beyond your calculated total for future repairs.
- Small jobs (under 200 pavers)Order from a single lot so color and finish match throughout
- Medium jobs (200–800 pavers)Confirm pallet count and set aside 3–5% extra from the same run for repairs
- Large jobs (800+ pavers)Order by the full pallet and ask your supplier to hold the lot or batch number
Common mistakes
- Not deducting fixed features from the patio areaFire pits, planters, and steps reduce the area that actually needs pavers
- Using the wrong coverage figure for paver sizeSquare, large-format, and cobblestone pavers cover very different square footage per unit
- Underestimating waste for cuts along bordersRunning-bond and herringbone patterns use more material than a straight grid layout
- Skipping the paver base sand layerA proper bedding sand layer keeps pavers level and prevents rocking or settling
- Mixing pavers from different lotsColor and texture variation between production runs is very noticeable on a finished patio
- Not ordering extra for future repairsDiscontinued paver styles make matching replacements difficult years later — keep 3–5% in reserve
What this calculator assumes
Adjust your result if your project differs from these.
- Coverage per paver (1.0 sq ft for 12×12in square, 2.67 sq ft for 16×24in large-format, 0.25 sq ft for cobblestone) assumes standard butt joints with polymeric sand.
- Openings for fire pits, planters, and other fixed features are subtracted from gross area before waste is applied.
- The default 10% waste allowance covers cuts, breakage, and border trimming.
- Paver base sand bags are estimated at roughly 1 per 50 square pavers; other sizes need proportionally different sand coverage.
- Paver and sand bag counts are rounded up to the nearest whole unit.
- Pricing is a regional estimate — confirm current paver and sand prices with your supplier.
Common questions
How many patio pavers per square foot?
12×12in square paver needs exactly 1 paver per sq ft, since each unit covers 1.0 sq ft including its joint.
Square vs large-format vs cobblestone — how does size change the count?
16×24in large-format paver needs about 62% fewer units than 12×12in square, while cobblestone needs about 4 times more units for the same area.
How much paver base sand do I need?
Roughly 1 bag covers 50 square pavers, though this varies with bedding depth and paver size.
How many pavers come on a pallet?
12×12in square patio paver typically ships around 100–140 pavers per pallet, depending on thickness.
Should I deduct fire pits or planters from the patio area?
Yes. Subtract the footprint of any fixed features from your gross patio area before calculating paver count.
How much waste should I add for patio pavers?
10% is standard for a simple grid pattern. Increase to 15% or more for herringbone, running-bond, or curved layouts.
What base do patio pavers need under them?
A compacted aggregate base topped with about 1 in of paver base sand is standard for most residential patios.
How much do patio pavers cost per square foot installed?
At $3.25 per paver and 1 paver per sq ft, material alone runs about $3.25 per sq ft before labor, base, and sand.
Can I mix paver sizes on one patio?
Yes, combining square and large-format pavers is a popular design choice — just calculate each size’s area separately for an accurate count.
Do I need edge restraints for a paver patio?
Yes. Plastic or metal edge restraints anchor the outer row of pavers and keep the whole field from spreading over time.
