Tile calculator
Calculate how many tiles you need for a floor or wall based on dimensions, tile size and waste.

Check packaging — typically 4–12 pcs/pack

Materials
14.04 m² for 12 m² (incl. waste)
10 × 4 = 40 pcs (surplus: 1 pcs)
ℹThe result is an estimate based on your dimensions, tile size, joint width and waste.
ℹFor diagonal patterns or many cutouts the actual waste may be higher than 10 %.
Example: 12 m² floor
If you lay 60×60 cm tiles on a 12 m² floor (4 × 3 metres) with 3 mm joints and 10 % waste, you need about 39 tiles or 10 packs.
The calculation looks like this:
The calculator always rounds up so you won't run short. Consider buying a few extra for future replacements.
How to calculate tiles
Why waste matters
Tiles must be cut along walls, corners and around pipes. Some also break during cutting. 10 % extra is a good starting point, but for diagonal patterns or many cutouts you should allow 15 %. The calculator automatically adds your chosen waste percentage.
Joint width affects tile count
The grout joint between tiles takes up space. With a 3 mm joint on a 600 mm tile the effective tile width becomes 603 mm. Across a whole floor this means you use fewer tiles than without joints — the calculator accounts for this so you get the precise count.
Larger tiles mean fewer joints
A 60×60 cm tile covers 0.36 m² each, while a 30×30 cm tile only covers 0.09 m². That means 4 times as many tiles and joints for the same area. Larger tiles give a cleaner look and fewer joints to maintain, but require a more level substrate.
