Area-based estimate, not a laying plan. Grout joints, patterns, edge cuts, adhesive and labor are not modelled. Enter net area after subtracting openings.

How this was calculated

Tile area = length in cm × width in cm ÷ 10,000.

Required tiles = surface area × (1 + waste/100) ÷ tile area, rounded up.

Round tiles ÷ tiles per box up, then multiply by box price.

Formula and method

Divide surface area including allowance by one tile’s face area and round up. Divide by tiles per box and round up again.

Worked example

For 20 m² with 10% extra and 30 × 30 cm tiles, 245 tiles are required. Boxes of 10 mean 25 boxes; at 25 currency units each, material costs 625.

Frequently asked questions

Does this plan the tile layout?

No. It is an area estimate. Patterns, grout joints and narrow edge cuts can change waste, so verify the laying plan before ordering.
