How to use this paver calculator
Enter the length and width of the area in feet or inches, the length and width of one paver in inches, and a waste allowance. The calculator shows the area in square feet, the exact number of pavers with no waste, and how many to buy with waste included. Enter a price per paver to see the estimated material cost. Use the Feet or Inches button to switch the area unit. If you switch units, your entered length and width are converted so the physical size stays the same.
How to calculate pavers
Multiply the area length by the area width to get square feet, then multiply by 144 to get square inches. Divide by the area of one paver in square inches to get the exact count, then add waste. For a 12 by 10 foot patio with 4 by 8 inch pavers: 12 times 10 equals 120 square feet, 120 times 144 equals 17,280 square inches, and one paver covers 32 square inches, so 17,280 divided by 32 equals 540 pavers. Add 10 percent waste and you should buy 594 pavers.
Pavers per square foot for common sizes
| Paver size | Pavers per sq ft |
|---|---|
| 4 × 8 in | 4.5 |
| 6 × 6 in | 4 |
| 6 × 9 in | 2.67 |
| 12 × 12 in | 1 |
How much waste to allow for pavers
Allow 5 to 10 percent waste for a simple rectangular patio with straight edges. Allow 10 to 15 percent when the patio has curves, angles, or a lot of cuts around edges and obstacles. Buy a few extra pavers beyond the waste allowance if you want spares for future repairs, since dye lots change between batches and a matching paver may not be available later.
Frequently asked questions
How many pavers do I need for a 10 by 10 patio?
A 10 by 10 patio is 100 square feet. With 4 by 8 inch pavers that is 450 pavers with no waste, and 495 pavers with 10 percent waste.
How do I calculate how many pavers I need?
Multiply the patio length by the width to get square feet, multiply by 144 for square inches, and divide by the area of one paver in square inches. Then add 5 to 15 percent for waste and cuts.
How much extra should I buy for cuts and waste?
Add 5 to 10 percent for a simple rectangle and 10 to 15 percent for curves, angles, or many edge cuts.
Do I count the border pavers separately?
No. Measure the full area including the border, since the calculator counts every paver the area needs. If the border uses a different size or color, calculate the border row on its own and add it to the field count.
What base goes under pavers?
Most patios sit on 4 to 6 inches of compacted gravel base with about 1 inch of bedding sand under the pavers. Driveways need a deeper base, typically 6 to 8 inches of compacted gravel.
