Paver Calculator

This free paver calculator turns your patio, walkway or driveway dimensions into a paver count, compacted base, bedding sand and a materials cost range — for concrete, clay brick or natural stone pavers.

What this calculator does

This planner converts your patio, walkway or driveway area into a paver count, compacted base gravel and bedding sand quantity, using your chosen paver's coverage and a waste allowance for cuts.

How the math works

  • Pavers: area (length × width), plus waste, divided by one paver's coverage.
  • Base & sand: area × depth (converted to feet), then to tons using each material's density.

Worked example

A 10 ft by 10 ft patio (100 sq ft) with 12x12 in concrete pavers: 110 pavers with a 10% waste allowance, about 2 tons of compacted base at 4 in deep, and about 0.5 tons of bedding sand at 1 in deep.

Frequently asked questions

How many pavers do I need for a patio?

Divide your area by one paver's coverage, then add 10% for cuts and waste. A 100 sq ft patio with 12x12 in pavers needs about 110 pavers.

How deep should the base be under pavers?

4 in compacted base is typical for a patio or walkway; a driveway often needs 6-8 in, plus a 1 in bedding sand layer on top.

Do I need sand under pavers?

Yes — a thin bedding sand layer between the compacted base and the pavers gives a level surface to set each paver into.

How much waste should I allow for pavers?

10% for a simple rectangular layout; complex shapes or patterns with more cuts may need 15% or more.

What is the cheapest paver option?

Concrete pavers are typically least expensive, followed by clay brick; natural stone costs the most.

Limitations

This tool estimates material quantities and typical bulk costs only. It doesn't include edge restraint, polymeric sand for joints, or account for complex cutting patterns.
