How to calculate
Estimate the number of tiles for a floor or wall.
Tiles = ceil(area ÷ (tile length × width / 10,000) × (1 + waste ÷ 100))
Worked example
Surface area (m²): 20; Tile length (cm): 60; Tile width (cm): 60; Waste allowance (%): 10.
Tiles needed: 62 .
Assumptions and limits
Area-based estimate. Layout, cuts, and grout spacing affect the final count; round up to full packs when ordering.
Results are rounded for display; calculations use unrounded values. Read our calculation methodology.
Understanding the result
Tile count converts the surface area into individual tile areas, applies your waste allowance, and rounds up to a whole tile.
When this tool is useful
Estimate an initial tile quantity before considering pack sizes and a detailed layout.
Understanding your inputs

| Waste allowance (%) | Enter a number of at least 0 and no more than 100. |
Frequently asked questions
Does the count include grout spacing?
No. Grout joints, edge cuts and layout patterns require a more detailed plan.
Can I order exactly this number?
Suppliers may sell full boxes only. Round the tile count up to a complete pack and confirm the layout allowance.
