Paver calculator
Pavers for a patio, walk, or driveway area — any rectangular unit size, cut waste included.

How it’s computed
Pavers = ceil(area × (1 + waste) ÷ paver face), where face = (length in × width in) ÷ 144 sqft. Defaults: 6×6 paver, 5% waste. For a rectangular area, pass length × width as the area.
Decimal-exact and deterministic: identical inputs always return identical results. This is the same math Ask Donnie’s estimating engine runs — not an approximation, and never a language model doing arithmetic.
Common questions
Herringbone or running bond?
Patterned lays cut more at the borders — raise the waste input above the 5% default, especially on narrow walks where edges dominate.
How much base do I need under them?
Use the gravel calculator with your bedding + base depth for the volume; base depth itself depends on soil and traffic — follow your paver manufacturer's guidance.
Need the whole estimate, not just this number?
Ask Donnie turns a description or a plan into a full itemized estimate — deterministic math, real cited pricing, an AACE accuracy class. Free to start, watermarked deliverables included.
