Free Paver Quantity calculator with clear step-by-step results.
About Paver Quantity
The repeating unit of a paved surface is the paver plus its joint, so a 200 × 100 mm block on a 3 mm joint occupies 203 × 103 mm and about 48 units fill a square metre. Cutting waste is higher than for brickwork because borders, radii and herringbone edges all need part units, and a cut paver rarely yields two usable pieces.
Formulas
Pavers per square metre
Pavers/m² = 1 ÷ ((length + joint) × (width + joint))
Order quantity
Pavers to order = ceil(area × pavers/m² × (1 + waste))
Worked example
With the default values below, Paver Quantity returns Pavers to Order of 1,550. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 5 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
- This is a surface take-off only. Sub-base depth, bedding, edge restraint and drainage falls must follow the paving design and local standards, particularly for vehicle loading.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions
Why does the joint change the count?
Joints add up. On a small 200 × 100 paver a 3 mm joint removes roughly 3% of the units per square metre, which is a meaningful number of pavers across a driveway.
How much waste should I allow for a pattern?
5% for a straight stretcher bond, 8-10% for herringbone or basketweave, and up to 15% where there are curves, circles or many obstacles.
Should I order extra beyond the waste allowance?
Yes — keep a small stock of spares from the same batch. Later production runs differ in colour, so a repair made years later will show.
