Paver Calculator
Measure the patio, pick a paver size and pattern, and get the piece count, pallets and edging you need to order — waste included.
Why the pattern changes how many pavers you buy
The same 24 × 14 area, laid five ways. Orange pieces are cut at the border — each one uses a whole paver but only covers part of one, and the offcut is usually too small to reuse.
Each row shifts by half a paver. Every other row ends in a half piece at both edges — that is where the extra comes from. Smaller patios have more edge per square foot, so their waste percentage runs higher than a big one laid in the same pattern.
How the paver count is worked out
pavers = area (sq ft) ÷ (W + joint) × (L + joint) ÷ 144 × (1 + waste)
Measure the finished surface, not the dug area. A 4×8-inch holland paver with a 1/8-inch joint covers 4.125 × 8.125 ÷ 144 = 0.233 sq ft, so a 192 sq ft patio needs about 825 pieces before waste. Add the waste allowance for your pattern and round up to whole pavers, then to whole pallets if the yard won’t split one.
Buying by square foot? Many yards price pavers per sq ft instead of per piece. Multiply the area by 1 + waste and order that many square feet — the piece count above is still useful for checking the delivery.
Common paver sizes and pieces per 100 sq ft
| Paver size | Covers (with 1/8″ joint) | Pieces / 100 sq ft | +10% waste |
|---|---|---|---|
| 4 × 8 in (holland / brick) | 0.233 sq ft | 430 | 473 |
| 6 × 6 in | 0.261 sq ft | 384 | 423 |
| 6 × 9 in | 0.388 sq ft | 258 | 284 |
| 6 × 12 in | 0.516 sq ft | 194 | 214 |
| 12 × 12 in | 1.021 sq ft | 98 | 108 |
| 12 × 24 in | 2.031 sq ft | 50 | 55 |
| 16 × 16 in | 1.806 sq ft | 56 | 61 |
| 24 × 24 in | 4.042 sq ft | 25 | 28 |
Before you order
- Thickness matters. 60 mm (2⅜ in) pavers are standard for patios and walks; driveways should use 80 mm (3⅛ in) pavers, which the Interlocking Concrete Pavement Institute (ICPI) recommends for vehicle traffic.
- Mix from several pallets. Colour varies batch to batch. Pull from three pallets at once as you lay to blend it.
- Edge restraint is not optional. Without plastic, aluminium or concrete edging, the outer rows creep and the joints open. The perimeter above is how much you need.
- Keep spares. A dozen leftover pavers make a future repair invisible.
Questions people ask
How many pavers do I need for a 10×10 patio?
A 10×10 patio is 100 sq ft. With 4×8-inch pavers (0.222 sq ft each) that is 450 pavers before waste; add 5–10% for a running-bond or herringbone pattern and buy about 475–495. With 12×12 pavers you need 100 plus waste, so roughly 105–110.
How much extra paver should I buy for waste?
Plan 5% for straight stack or running bond with few cuts, 10% for 90° herringbone, curves or lots of obstacles, and 15% for 45° herringbone or diagonal layouts. Keep a few spares after the job for future repairs — matching colour later is hard.
Do I include the joint gap when counting pavers?
Yes, if your joints are wider than about 1/16 inch. Each paver covers its own face plus half the joint on each side, so wider joints mean slightly fewer pieces. Most concrete pavers have spacer nubs that set a 1/8-inch joint; this calculator adds the joint to each dimension.
How many pavers are on a pallet?
It depends on the paver size and thickness. A pallet of standard 60 mm concrete pavers typically covers roughly 90–130 sq ft, so a pallet of 4×8 holland stones holds about 400–600 pieces. Check the supplier sheet for the exact square footage per pallet and enter it here.
How do I calculate an L-shaped or curved patio?
Split it into simple shapes — rectangles, circles and triangles — and add them together. Use “Add another section” above for each piece. For a half circle, enter the full-circle diameter and halve the result, or measure it as a triangle-and-rectangle approximation.
