Paver Block Quantity Calculator

Work out paver block quantity instantly with clear inputs, formula shown and shareable results.

About Paver Block Quantity Calculator

Pavers per square metre is a million divided by the face area of one paver in square millimetres, so a 200 by 100 mm block gives 50 per square metre. A cutting allowance is essential because edges and radii waste whole units. Bedding sand is laid 50 mm thick and jointing sand runs about 3 kg per square metre.

Formulas

Pavers per m²

Count = 1,000,000 / (length mm x width mm)

Quantity

Pavers = area x pavers per m² x (1 + wastage)

Worked example

With the default values below, Paver Block Quantity Calculator returns Pavers required of 5,250. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 4 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 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the Paver Block Quantity figure worked out?

Count = 1,000,000 / (length mm x width mm). Pavers per square metre is a million divided by the face area of one paver in square millimetres, so a 200 by 100 mm block gives 50 per square metre.

Why 50 mm of bedding sand?

It is enough to accommodate paver thickness tolerance and let each unit be vibrated to level, but thin enough that it does not rut under load. Thicker beds settle unevenly.

What values do I need to enter?

This calculator takes 4 inputs: Area to pave, Paver length, Paver width, Cutting and breakage allowance. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
