About this calculator
Counts pavers by area rather than by row, then adds waste for cuts around edges and curves. Curved layouts waste far more than rectangles — bump the allowance to 15%.

FAQ
How does the paver calculator work?
Counts pavers by area rather than by row, then adds waste for cuts around edges and curves. Curved layouts waste far more than rectangles — bump the allowance to 15%. The underlying maths is: Pavers = Area ÷ (Paver length × width in feet), plus waste.
What do I need to enter?
5 values: patio area, paver length, paver width, price per paver, and waste allowance. Each field starts with a sensible default, so you can change one number at a time and watch the result move.
What does the pavers needed result mean?
It is returned as a whole number and updates live as you edit the inputs, so you can compare two or three versions of a scenario in a few seconds.
Is this calculator free, and do I need an account?
Yes, it's free, and no account is required. Nothing you type is stored on our servers — the maths runs entirely in your browser.
How accurate is the result?
It applies the standard formula exactly, so the arithmetic is precise. Estimates assume standard, average conditions — local rules, pricing, and materials vary.
Who is this tool for?
It's built for anyone doing everyday planning maths — a quick estimate that would otherwise need four browser tabs and a calculator app.
Accuracy and limitations
- Estimates assume standard, average conditions — local rules, pricing, and materials vary.
- Results are rounded for readability; add a buffer before ordering, booking, or committing.
- Double-check anything with a real cost attached against a local quote.
