How Many Pavers Do I Need? (Calculator + Pattern)
Quick answer: area ÷ paver area, then add waste. A 12×12 ft patio at 12×12 in pavers needs 144 pavers before waste; with 10% that's about 159 pavers. Here's the full method.

Paver quantity formula
Pavers come in fixed sizes (commonly 12×12 in, 4×8 in, 6×6 in). Convert everything to inches or feet and divide the patio area by the paver area:
Patio area ÷ paver area = pavers, then add waste and divide by pavers per pallet for your order. Keep the units straight — work everything in square feet. A 12×12 in paver is 1 sq ft; a 4×8 in paver is 0.222 sq ft; a 6×6 in paver is 0.25 sq ft.
Measure the patio as length × width for a rectangle. For an irregular or L-shaped patio, split it into rectangles, measure each, and add them — the same method you'd use for flooring.
Waste by pattern
| Layout | Waste |
|---|---|
| Straight / grid | 5–10% |
| Running bond | 10% |
| Basketweave | 10% |
| Herringbone | 10–15% |
The pattern drives the waste because angled layouts force more edge cuts. Herringbone and running bond waste more per square foot than a straight grid, so plan the pattern before you order. On top of pattern waste, always add a small buffer for broken pavers in transit — pavers are brittle and a damaged corner is useless for a finished edge.
Worked example
- Patio = 12 × 12 = 144 sq ft
- Paver = 12 × 12 in = 1 sq ft
- Pavers = 144 ÷ 1 = 144
- Add 10% waste = 158–159 pavers
A 4×8 in paver is 32 sq in = 0.222 sq ft, so the same 144 sq ft patio needs about 648 pavers. Always round up to the nearest whole paver (or half-pallet) — you can't buy a single paver mid-job if a dye lot ran out.
Sand and base
Beyond pavers, plan for a 4-in compacted gravel base, bedding sand (about 1 in), and joint sand. A common rule: 1 ton of paver sand covers roughly 40–60 sq ft at 1 inch. Account for edging too.
The base is what keeps the patio level for years. Skip the compacted gravel base and your pavers will settle unevenly after the first rainy season — that's the difference between a patio that stays flat and one that becomes a tripping hazard.
Ordering tips
Order ~10% extra and buy it all at once — dye lots differ between batches and pavers crack in transit. For a patio that might extend later, keeping a few spares is smart. A pallet typically holds about 110–120 sq ft of pavers depending on size.
Ask your supplier whether the pallet is quoted by square footage or by paver count — the two can differ, and it's the single easiest confusion to avoid when ordering.
Common mistakes
- Mixing inches and feet. A 12×12 paver is 1 sq ft, not 12 sq ft.
- No waste. Cutting edge pavers and broken pieces add up.
- Forgetting base and sand. Pavers without a proper base settle and shift.
- Buying across batches. Color variation is real — order everything at once.
- Ignoring the pattern before ordering. An angled layout needs a bigger waste allowance.
FAQ
A 10×10 ft patio is 100 sq ft. At 12×12 in pavers (1 sq ft each) you need 100 pavers, plus 10% waste = about 110 pavers.
Add 5–10% for a straight layout and 10–15% for herringbone or angled patterns, since edge cuts and broken pavers consume more.
A pallet typically covers about 110–120 square feet of pavers, but the count depends on the paver size. Confirm with your supplier.
Yes — a compacted gravel base topped with about 1 inch of bedding sand, plus joint sand between pavers, is the standard installation.
