Pavers needed by project area
This planning chart adds 10% and rounds up to whole pavers. Use the actual dimensions supplied by your paver manufacturer when ordering.
| Project area | 8×4 in | 12×12 in | 12×18 in | 16×16 in | 18×18 in | 24×24 in |
|---|---|---|---|---|---|---|
| 50 ft² | 248 | 56 | 37 | 31 | 25 | 14 |
| 100 ft² | 496 | 111 | 74 | 62 | 49 | 28 |
| 144 ft² | 713 | 159 | 106 | 90 | 71 | 40 |
| 150 ft² | 743 | 165 | 111 | 93 | 74 | 42 |
| 200 ft² | 991 | 221 | 147 | 124 | 98 | 56 |
| 250 ft² | 1238 | 275 | 184 | 155 | 123 | 69 |
| 300 ft² | 1486 | 330 | 221 | 186 | 147 | 83 |
| 400 ft² | 1981 | 441 | 294 | 248 | 196 | 111 |
| 500 ft² | 2475 | 550 | 367 | 310 | 245 | 138 |
Counts include 10% extra. Multi-size patterns, borders, curves and manufacturer-specific dimensions can change the takeoff.
Paver formula
Pavers needed = project area ÷ paver face area. When working in feet and inches, convert the paver face area to square feet first: length in inches × width in inches ÷ 144. Multiply the resulting paver count by 1.10 for a 10% allowance, then round up.
Circular paver calculator formula
For a circular patio, calculate the area first: circle area = π × radius². If you measured diameter, divide it by 2 to get the radius. Then divide the circle area by the face area of one paver and add a cutting allowance.
Example: a 12 ft diameter circle has a 6 ft radius and an area of about 113.1 ft². With 12 × 12 in pavers, that is about 114 pavers before extra material, or about 125 pavers with 10% extra. Curved edges can create more waste than a rectangular layout, so the actual allowance may need to be higher.
Common patio examples
| Project | Area | Paver size | Exact field count | With 10% extra |
|---|---|---|---|---|
| 10 × 10 patio | 100 ft² | 12×12 in | 100 | 111 |
| 12 × 12 patio | 144 ft² | 12×12 in | 144 | 159 |
| 10 × 20 patio | 200 ft² | 12×12 in | 200 | 221 |
| 15 × 20 patio | 300 ft² | 12×12 in | 300 | 330 |
Don't stop at the paver count
A paver project also needs a prepared aggregate base and a bedding layer. The appropriate depths depend on the application, site conditions, product system and local practices. Instead of estimating each material independently, use the Paver Calculator for the complete takeoff.
Calculate paver base gravel
If you already know your compacted base depth, the Paver Base Calculator converts project area and depth into cubic yards, approximate tons and bag equivalents.
Calculate bedding sand
Use the Paver Sand Calculator when you need bedding-sand volume from area and planned depth.
Frequently asked questions
How do I calculate how many pavers I need?
Multiply the project length by width to get square feet, divide by the face area of one paver, then round up and add an allowance for cuts, breakage and layout. The table on this page uses 10% extra.
How do I calculate pavers for a circular patio?
Find the circle area with π times radius squared, divide that square footage by the face area of one paver, then add extra for cuts. Circular layouts usually create more edge cuts than a simple rectangle.
How many 12 × 12 pavers do I need for a 12 × 12 patio?
A 12 × 12 ft patio is 144 square feet. One 12 × 12 in paver covers 1 square foot, so the exact field count is 144. With 10% extra, plan for about 159 pavers.
How much paver base and sand do I need?
Base and bedding-sand quantities depend on project area and the compacted depths you plan to use. Use the PlanDIYBuild Paver Calculator to calculate pavers, base gravel and bedding sand together.
