Quick answer
What does the Paving stone quantity calculate?
How many pavers cover the area including cuts and waste? This calculator uses area length, area width, paver length, paver width, cuts and waste, and pavers per pack to estimate pavers to order immediately in your browser.
With the values currently entered, the result is 1320 pavers — quantity to order in full packs. It also shows full packs, calculated pavers, order area, and base area.
How to use the Paving stone quantity
- Replace the example values with your own numbers.
- Review the result and supporting figures as they update automatically.
- Check the formula and assumptions before using the estimate for a decision.

Practical guide
Paving stone quantity example and edge cases
How many pavers cover the area including cuts and waste? Let's use a concrete example, then look at the assumptions that can move the answer.
Example: A practical paving stone quantity scenario
For this example, use area length of 6 m, area width of 4 m, paver length of 20 cm, paver width of 10 cm, cuts and waste of 8 %, and pavers per pack of 40 pavers. These are starting values, so replace them with numbers that match your situation.
- Area length
- 6 m
- Area width
- 4 m
- Paver length
- 20 cm
- Paver width
- 10 cm
- Cuts and waste
- 8 %
- Pavers per pack
- 40 pavers
Calculated result1320 paversquantity to order in full packs
Start with quantity to order in full packs. Then check full packs, calculated pavers, order area, and base area to understand what sits behind the main result.
Example results use the default display profile. The calculator above follows your selected country and units.
How to read the result
- Read the main result first. The supporting figures for full packs, calculated pavers, order area, and base area explain how the estimate is built.
- The method is Area × waste allowance ÷ individual paver area, rounded to full packs. Keep the units consistent and use values from the same time period.
Edge cases worth checking
When area length is unusual
The paved area is rectangular. Double-check this input before relying on the result.
When pavers per pack is uncertain
Joint width and pattern effects are included only through waste. Run a lower and higher value to see a useful range.
What changes the result most
Area length
Measure area length with the same unit shown beside the input. Convert first if your source uses another unit.
Area width
Measure area width with the same unit shown beside the input. Convert first if your source uses another unit.
Paver length
Measure paver length with the same unit shown beside the input. Convert first if your source uses another unit.

Common mistakes
Check area length
The paved area is rectangular. Make sure this matches the number you enter.
Keep pavers per pack consistent
Joint width and pattern effects are included only through waste. Use the same units and time period throughout the calculation.
Do not rely on one paving stone quantity scenario
Run a cautious case and an optimistic case. The range is often more useful than one exact-looking number.
