実例

Example: With Area (m²) = 10, Paver length (m) = 0.4, Paver width (m) = 0.4, Waste (%) = 5, the Paver Calculator gives Pavers Needed: 66, Paver Area M2: 0.16.

よくある質問

How much waste allowance should I use for pavers?

10% is typical for a running-bond pattern; herringbone or diagonal layouts often need 12-15% due to more edge cuts.

Does this account for the base and joint sand?

No, this calculates paver units only — plan separately for gravel base and polymeric joint sand.

What inputs does the Paver Calculator need?

You'll need to provide: Area (m²), Paver length (m), Paver width (m), Waste (%). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.

How accurate is the Paver Calculator?

The Paver Calculator applies the formula exactly as calculated — Pavers needed = (area ÷ paver area) × (1 + waste%), rounded up, where paver area = paver length × paver width. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.

Is the Paver Calculator free to use?

Yes, the Paver Calculator is completely free, requires no signup, and runs instantly in your browser.
