Paver blocks for a driveway, path or yard are just the area divided by one block's area, plus a bit for cuts — this calculator does it for the common sizes. Enter the area and pick the paver, and it gives the number of blocks including wastage.

Lay pavers over a compacted base and sand bed, with edge restraints so they don't creep. Keep a few spares from the same lot for repairs. For a concrete driveway instead, see the concrete calculator.

How the calculation works

Blocks = Area × (1 + wastage) ÷ one-block area

A 200 × 100 mm paver covers 0.02 m², so 50 blocks make one square metre. For 100 m² with 5% wastage:

  • Blocks = 100 × 1.05 × 50 = 5,250 blocks

Blocks per square metre by size

Larger pavers mean fewer blocks but each is heavier; interlocking I-shape (zigzag) pavers lock together and suit driveways with vehicle loads.

Laying pavers

Pavers sit on a compacted sub-base, a sand bedding layer and are held by edge restraints so they don't spread. Joints are filled with fine sand. Keep a few spares from the same lot for later repairs. For a poured concrete driveway instead, use the concrete calculator, and estimate any earthwork with the excavation calculator.

Frequently asked questions

How many paver blocks are in 1 square meter? For the common 200 × 100 mm paver, 50 blocks cover one square metre. Larger 300 × 300 mm pavers need about 11 per square metre.

How do I calculate the number of paver blocks? Divide the area by one block's area, then add wastage. For 200 × 100 mm pavers, that is area × 50 × (1 + wastage). For 100 m² with 5% wastage, 5,250 blocks.

How much wastage should I allow for pavers? Allow about 5–10% for edge cuts and breakage — more for curved or complex layouts with many cuts.

What size paver block is best for a driveway? Interlocking I-shape (zigzag) pavers, usually 225 × 112.5 mm and 60–80 mm thick, are preferred for driveways because they lock together and carry vehicle loads well.

What goes under paver blocks? A compacted sub-base, then a sand bedding layer, with edge restraints around the perimeter. Joints are filled with fine sand after laying.
