How this is calculated
pavers = area ÷ (paver width × paver length ÷ 144), plus waste; sand = area × (depth ÷ 12) ÷ 27
- 10% waste suits a running bond; allow 15% or more for herringbone or a curved edge, which produces far more cuts.
- Edge restraint is the full perimeter — subtract any side that meets an existing wall.
- A 1 in bedding sand layer is standard over a compacted gravel base.
Frequently Asked Questions
How does the Paver Calculator work?
It applies the formula pavers = area ÷ (paver width × paver length ÷ 144), plus waste; sand = area × (depth ÷ 12) ÷ 27. Enter your measurements and the result updates instantly in your browser — nothing is uploaded and no sign-up is needed.
Why should I include a waste allowance?
Offcuts, spillage, breakage and an uneven sub-base all consume material that the raw geometry does not account for. The default allowance is deliberately modest; increase it for complex layouts, and remember that running short usually costs more in a second delivery than the surplus did.
Are the results exact?
They are a close estimate, not a guarantee. 10% waste suits a running bond; allow 15% or more for herringbone or a curved edge, which produces far more cuts. Real materials vary by supplier, moisture content and compaction, so confirm the rate with your supplier before placing a large order.
Is this tool free?
Yes, completely free with no registration. All calculations happen client-side in your browser.
Does it work on mobile?
Yes. The calculator is fully responsive and works on phones and tablets in any modern browser — useful when you are measuring on site.

About the Paver Calculator
The Paver Calculator divides your patio area by the size of a single paver, adds a waste allowance for cuts, and works out the bedding sand and edge restraint alongside it. Enter your measurements and the result updates as you type — there is nothing to submit and nothing to wait for.
Everything runs in your browser. Nothing you enter is sent to a server, there is no sign-up, and there is no usage limit.
Who it's for
Anyone laying a patio, path or driveway in pavers.
How the calculation works
pavers = area ÷ (paver width × paver length ÷ 144), plus waste; sand = area × (depth ÷ 12) ÷ 27
The result depends on a few standard constants, which are stated on the page rather than hidden:
- 10% waste suits a running bond; allow 15% or more for herringbone or a curved edge, which produces far more cuts.
- Edge restraint is the full perimeter — subtract any side that meets an existing wall.
- A 1 in bedding sand layer is standard over a compacted gravel base.
Getting an accurate estimate
Measure twice. Small errors in a linear dimension compound, because material volume scales with two or three of them at once — a 6-inch error across a 20-foot run is over a cubic foot of material on a 4-inch pour.
Keep the waste allowance. The default is deliberately conservative: offcuts, spillage, uneven sub-base and breakage are all real, and running short mid-job usually costs more in a second delivery than the surplus did.
Round up when you order. Suppliers sell in fixed increments — quarter yards, whole bags, full boxes — so treat the figure here as the minimum you need rather than the exact amount to buy.
