Explain this equation
Use this to order tile levelling clips for a floor or wall.
cL and cW are how many clips you set along a long and a short edge. L × W / 1 000 000 is the area of one tile in m². A is the area to tile and w covers cut tiles and breakages.
Every edge is shared by two tiles, so of a tile’s four edges it effectively owns one long and one short. Clips per tile are therefore cL + cW, and dividing by the tile area gives clips per m².
600 × 600 with two clips a side: 4 ÷ 0.36 ≈ 11 per m². 1200 × 600 with four on the long side and two on the short: 6 ÷ 0.72 ≈ 8 per m². These match LevTec’s table.
Watch out: do not count all four sides of every tile; that doubles the order. Cut edges need extra clips.
Counts levelling clips for a floor or wall from the tile size and how many clips go on each edge.

Good to know
Every edge is shared by two tiles, so each tile accounts for one long side and one short side: clips per tile = cL + cW. LevTec’s table follows this: two clips per side on 600 × 600 gives 11 per m², 2 and 4 on 600 × 1200 gives 8, four per side on 1200 × 1200 gives 6. A common rule is roughly one clip every 250–300 mm of edge, at least two per side on tiles 300 mm and over, and one per short end on narrow planks.
Common mistake
Counting clips round all four edges of every tile, which doubles the order.
Limits
Clips are single use; wedges or caps are reusable and counted separately. Cut tiles at the edges need extra clips, so keep the waste allowance.
