Paver Calculator
Estimate how many pavers you need for a patio, walkway or driveway — accounting for the joint gap between pavers, a wastage percentage for cuts and breakage, and an optional price per paver, in metric or imperial units.
Input
Metric enters the project area in metres and the paver/joint in millimetres; imperial uses feet and inches.
Total project length (metres in metric, feet in imperial).
Total project width (metres in metric, feet in imperial).
Single paver length (millimetres in metric, inches in imperial).
Single paver width (millimetres in metric, inches in imperial).
Sand/polymeric-sand gap between pavers (millimetres in metric, inches in imperial). Leave blank for edge-to-edge laying.
Extra pavers for cuts, breakage and pattern trim (5-10% for a running-bond layout, 15%+ for a complex or diagonal pattern).
Leave blank to skip the cost estimate.

The Paver Calculator estimates how many pavers you need for a patio, walkway or driveway. Enter your project dimensions and a single paver's size and it works out the project area, the effective footprint of one paver (including the joint gap between pavers), and how many to order — with and without a wastage allowance. Add a price per paver to see the total material cost. It supports metric (m / mm) and imperial (ft / in) input.
How to use it
- Pick your unit system — metric (project in metres, paver/joint in millimetres) or imperial (project in feet, paver/joint in inches).
- Enter the project length and width.
- Enter the paver's length and width, and the joint gap left between pavers for sand or polymeric sand.
- Set a wastage percentage for cuts, breakage and pattern trim.
- Optionally enter a price per paver to see a total material cost.
Results update instantly. The table shows project area, effective paver footprint, pavers needed (with and without wastage), extra pavers for waste, the estimated coverage your purchase gives you, and the estimated cost. A one-line summary is provided for quick copying.
How is the paver count calculated?
Each paver is treated as occupying an effective footprint of (paver length + joint gap) x (paver width + joint gap) — the same way tile and brick calculators account for a grout or mortar gap. Dividing the project area by this footprint gives the base paver count, then the wastage percentage is applied and the result rounded up.
What joint gap should I use?
Most paver installations leave a 1/8in to 1/4in (3-6mm) gap filled with polymeric sand. Set it to 0 to estimate coverage from the bare paver face alone (a tight, mortared installation).
How much wastage should I add?
5-10% is typical for a straightforward running-bond layout. Add more (15%+) for a herringbone, basket-weave or diagonal pattern, curved borders, or lots of cuts around edges and fixtures.
Does it estimate cost?
Only if you enter a price per paver — it's optional. Leave it blank to see quantities only; the total cost is the wastage-adjusted paver count multiplied by the price you enter.
