Tile Calculator

Estimate how many mosaic sheets you need for a wall or floor. Enter one or more rectangular areas, choose a wastage allowance, and use the sheet dimensions shown on your chosen product.

Calculate your tiled area

You can add separate walls or floors. For irregular spaces, divide the area into rectangles. Only include the surfaces you intend to tile.

Area 1

The selected unit applies to both dimensions in that area. If you change units, enter the dimensions in the new unit.

Wastage allowance

10% is an editable starting point, not a universal requirement. Wastage varies with cuts, pattern, layout and installation. Ask your installer if you are unsure.

Mosaic sheet size

300 × 300 mm is an editable example. ExoTiles sheets vary in size. Use the full sheet dimensions, not the size of an individual mosaic piece. Changing the unit does not convert the entered numbers.

How the tile quantity calculator works

The calculator adds the areas of your rectangles, applies your chosen wastage percentage, then divides by the rectangular coverage of one sheet. For example, 2 × 3 m with 10% wastage gives 6.6 m². With 300 × 300 mm sheets (0.09 m² each), the estimate is 74 sheets.

For interlocking or irregular sheets, check the product's stated coverage rather than assuming its outer dimensions represent coverage. This first version estimates whole sheets, not boxes, grout or adhesive.
