How many tiles for 25 m² using 600×600 mm tiles?
You'll need 77 tiles to cover 25 m² with 600×600 mm tiles, including a 10% cutting waste allowance.
This is a large-format tile — fewer grout lines and a faster-looking finish, but it often takes two people to place each tile without cracking it.

Assumptions
- 10% cutting/wastage allowance, the /site/materials calculator default.
- Straight (grid) lay. Diagonal, herringbone or feature layouts typically need more waste.
Check before you order: Confirm the exact tile size and lay pattern with your tiler — offset, diagonal and herringbone layouts all waste more than a straight lay — and buy a few extra of the same batch for future repairs.
How this is worked out & FAQ
How this is worked out
- Work out the area per tile from its width and length in mm.
- Add the waste allowance to the area you're tiling.
- Divide by the area per tile and round up.
FAQ
Does this allow for a pattern lay?
No — this is a straight lay allowance. Diagonal, herringbone or feature layouts need a higher waste percentage; use the calculator directly to raise it.
Should I buy extra for future repairs?
Yes — tile batches (and even the same range) can vary in shade between production runs, so keep spare tiles from the same batch rather than trying to match one later.
