What is this calculator for?
Buying too many spacers wastes money. Buying too few stops you in the middle of a job, ruins your mortar batch and forces you to rush. This tool applies professional tilers' rules to give you the right quantity, bag by bag, in seconds.
Area + format
Enter the area to tile and the tile size. The tool computes the number of tiles to install.
Pick a system
Classic cross spacers or leveling clips: the formula adapts automatically.

You get the exact number of bags to buy, ready to copy and paste into a jobsite memo.
How to use it (4 steps)
- Area (m²): the surface to tile, excluding baseboards.
- Tile format: length × width in centimetres (e.g. 60 × 60, 20 × 120).
- Spacer type: leveling (clips + wedges) for large formats, classic (cross) for smaller tiles.
- Options: joint thickness, baseboards, multi-day install, available bag sizes.
The result updates in real time and the visual preview shows how spacers are arranged on 4 tiles.
The 10% safety rule
The result already includes a +10% safety margin. Broken clips, lost spacers in mortar, complex cuts along walls: real-world consumption is always higher than theory. This margin avoids the dreaded last-minute store run.
Save wedges with a multi-day install
Wedges are reusable, unlike clips. By splitting your install over several days, you can free wedges from day 1 and reuse them on day 2. The "multi-day" option divides the wedge count accordingly, with a minimum of 50 wedges so you're never stuck.
FAQ
How do I choose between classic and leveling spacers?
Simple rule: below 30 cm tiles, classic crosses are enough. Between 30 and 60 cm both work (leveling is more comfortable). Above 60 cm — especially for rectangles (20×120, 30×120) — leveling is strongly recommended to avoid lippage.
Which joint thickness should I pick?
For rectified indoor tiles, 2 mm is now standard. For non-rectified tiles, plan 4–5 mm. Outdoors or for very large formats, 6 mm is common. If unsure, let the tool auto-suggest based on tile size.
Why does the calculation add 10%?
On real jobsites, clips break, some are lost in mortar, and edge cuts use more than full tiles. The +10% avoids the dreaded store run mid-install. On very large projects (>100 m²) the margin can feel tight — round up to the next full bag if in doubt.
What about diagonal or herringbone layouts?
The total number of tiles and spacers stays roughly the same — the 10% margin absorbs extra cuts. For herringbone or diagonal patterns, plan 15% extra on the tiles themselves (use our dedicated tile-quantity tool).
Can wedges be reused?
Yes, fully. The clip (white base) stays trapped under the tile and is sacrificed, but the wedge (driven in with the gun) is reusable indefinitely. That's why a multi-day install lets you buy fewer wedges than clips.
