Paver Calculator

Estimate pavers, whole boxes and separate base and bedding volumes.

Units

Example shown — use your own measurements.

Use the product’s installed coverage including its stated joint basis.

Enter the project-specified depth. Zero omits this layer.

Extra options & cost (optional)

Applied once. Choose an allowance for your project; zero adds no extra material.

Fractions and number formats

Use decimals (12.5), fractions (12 1/2 or 12-1/2), or explicit lengths (12ft 6in, 12′ 6″, 25 mm). A comma followed by one or two digits is a decimal comma: 12,5 = 12.5. Grouped commas mean thousands: 1,200 = 1200. Use a decimal point for ambiguous values. Scientific notation is not accepted.

About this calculator

Estimate pavers, whole boxes and separate base and bedding volumes. Enter your measurements and check the worked example below. Product quantities use the label information you supply.

How to measure

  • Measure the actual usable surface or internal space, using the field labels for the selected mode.
  • Keep openings and excluded areas separate so they are subtracted once.
  • Recheck units and label coverage before ordering.
1. Length2. Width
Measurement guide, not to scale. Follow the field labels for the selected mode.

How to use this calculator

  1. Enter the patio or path area and subtract any exclusions once.
  2. Enter installed coverage per paver and pavers per box from the selected product.
  3. Enter the project-specified base and bedding depths separately; zero omits a layer.
  4. Apply any extra paver allowance once, then read whole boxes and the separate geometric layer volumes.

Formula

Pavers = ceiling(net area × allowance factor / installed coverage per paver)

Boxes = ceiling(pavers / pavers per box)

Base and bedding volume = net area × each selected depth; no compaction factor

Assumptions

  • Installed coverage includes the selected product’s stated joint basis.
  • Base and bedding quantities use net area times each entered depth and do not apply a loose-to-compacted conversion.
  • Extra allowance applies once to paver purchasing; whole pavers and boxes round up.

Common mistakes

  • Applying the same allowance in both measurements and the extra-material field.
  • Entering coverage or yield from a different product or measurement basis.
  • Treating a quantity estimate as an installation or structural approval.

Worked example

Try it: press “Load example” above the form.

100 ft² at 1 ft² per paver needs 100 pavers. At 10 per box, buy 10 boxes before extra. A 4 in base is 33⅓ ft³.

Limitations

This does not specify base depth or design pavement for traffic, soil, frost, drainage or loads. Installed coverage must match the product and joint basis. Base/bedding are geometric volumes, not loose-material delivery quantities.

Frequently asked questions

Does paver coverage include the joints?

Enter the installed coverage per paver on the product’s stated joint basis. Do not add another joint allowance to coverage that already includes it. The form rounds to whole pavers and then whole boxes.

What does the worked example show?

100 ft² at 1 ft² per paver needs 100 pavers. At 10 per box, buy 10 boxes before extra. A 4 in base is 33⅓ ft³.

Does the base volume include compaction?

No. Each layer volume is net area times the depth you enter. Obtain a suitable loose-to-compacted conversion separately if a delivery quantity must fill a specified finished layer.

Does this design base depth or pavement strength?

This does not specify base depth or design pavement for traffic, soil, frost, drainage or loads. Installed coverage must match the product and joint basis. Base/bedding are geometric volumes, not loose-material delivery quantities.
