Formula
Pavers needed = (area × (1 + wastage%)) ÷ paver area, rounded upWorked example
6m × 4m patio, 40cm × 40cm pavers, 10% wastage
| Field | Value |
|---|---|
| Area length (m) | 6 |
| Area width (m) | 4 |
| Paver length (cm) | 40 |
| Paver width (cm) | 40 |
| Wastage allowance (%) | 10 |
| Pavers needed | 165 |
| Area | 24 |
Assumptions
- Rounds up to a whole number of pavers, since partial pavers can't be purchased.
- Does not account for jointing sand gaps between pavers, which are usually small enough to be covered by the wastage allowance.
Frequently asked questions
What paver size should I use?
400×400mm is a common size for patios and walkways, but enter your specific product's dimensions for an accurate count.
Is this the same as the Tile Calculator?
Yes — same underlying calculation, framed here for outdoor paving with larger default unit sizes.
Does this include base material (sand/gravel bedding) quantities?
No — this only calculates the number of pavers. See the Gravel Calculator for base material quantities.
