Paver Calculator — How Many Pavers Do I Need
Paver counts are pure area division — patio square inches divided by paver square inches — plus a waste factor for cuts. This paver calculator does exactly that for your patio dimensions and paver size, adds 10% cutting waste (15% for curves or herringbone), and estimates polymeric joint sand, with 2026 material costs. The waste factor is the part people skip: every edge and curve eats partial pavers, and dye lots change between orders.
10% for rectangles; 15% for curves, circles, or herringbone patterns
Show the math
Patio area = 16 × 12 × 144 = 27648.0 sq in
Paver area = 4 × 8 = 32 sq in
Raw pavers = 27648.0 ÷ 32 = 864.0 (rounded up)
With 10% waste = 864.0 × 1.10 = 951.0 (rounded up)
Polymeric sand = 192.0 sq ft ÷ 100 sq ft/bag = 2 bags (rounded up)
What the numbers mean
The calculator converts your measurements into a practical purchase quantity using a documented coverage or spacing assumption.
Any whole-unit quantity is rounded up so the result does not leave you short during the project.
Use the cost range as a planning baseline and confirm the final quantity, availability, and delivery charge with your local supplier.
2026 material prices

Pro tips
- Order all pavers at once from the same pallet batch — dye lots shift and a second order will never match exactly.
- 10% waste covers rectangles; go 15% for herringbone, circles, or lots of curves — cuts multiply fast.
- Do not forget the soldier-course border in your count — it is included in the area math, but order a contrasting color separately if you want one.
- Keep a dozen spare pavers after the job; future repairs with matching pavers are priceless.
- A 16×12 patio needs 951 standard 4×8 pavers — that is roughly two full pallets, so plan delivery.
- Sweep polymeric sand in when the pavers are completely dry, then mist — wet pavers make the sand clump and stain.
Common questions
Frequently asked questions
How many 4×8 pavers for a 16×12 patio?
192 sq ft = 27,648 sq in ÷ 32 sq in per paver = 864, plus 10% waste = 951 pavers.
How many 12×12 pavers for the same patio?
27,648 ÷ 144 = 192, plus 10% waste = 212 pavers.
How much waste should I add?
10% for simple rectangles; 15% for herringbone patterns, curves, or circles.
How much polymeric sand do I need?
About one 50-lb bag per 100 sq ft — 2 bags for a 16×12 patio.
Do I count the border separately?
The area math includes it; if you want a contrasting border color, subtract the border area and order that color separately.
What do pavers cost per square foot?
$3–$8 per sq ft for materials — a 16×12 patio runs about $576–$1,536 in pavers alone.
