Material demand
Calculate tile material demand reliably.
Format, joint width, thickness, and reserve feed directly into clear purchasing quantities.

Material planning in the full workflow
Inputs, surface, and output are visible in one workspace, reducing rework and ordering errors.
From your layout to your order quantity
This calculator focuses on your purchase: count full tiles and tiles for cuts, add a reserve and round up to whole packs.
31 + 28 = 59 → × 1.10 → 65 tiles → 17 packs of 4
Example: L-shaped room 4.80 × 3.60 m minus 1.20 × 1.20 m, 60 × 60 cm tiles, 3 mm joints, grid offset 20 cm on both axes. No offcut reuse, 10% reserve. Four tiles per pack is an example assumption; use your product’s actual pack size.
What matters in practice
Result with clear quantity logic
Full tiles, cuts, waste, and total incl. reserve are shown transparently.
Practical input settings
Tile size, joint width, thickness, and reserve directly affect resulting quantities.
What this page is used for in real projects
You derive reliable quantities from concrete inputs and avoid over-ordering or shortages.

Examples from the tool
This is what it looks like planned out
The numbers above do not come from a spreadsheet but from a real layout. You can open these example projects directly – floor plan, laying plan and material list, exactly as the tool outputs them.

Three-room flat, one grid
Six rooms, eleven walls, five doorways – and a single herringbone grid running through every opening. Material is calculated for the whole flat at once.
- 63.79 m² across 6 rooms
- 90 × 30 herringbone, one grid
- 334 planks · 199 cuts

Small bathroom with tub and stud wall
Under 3 m² of floor left, but two cutouts: this room produces more cut tiles than full ones – exactly where the m² rule of thumb fails.
- 2.82 m² · 30 × 60 · 2 mm joint
- 9 full tiles, 22 cuts
- 35 tiles incl. 10% reserve
