Tile Calculator
Tile count is calculated by dividing floor area by tile area. This calculator estimates the number of tiles needed for a given area and tile size, with options to round up for waste.
What Is Tile?
Tile count is the number of tiles required to cover a floor or wall, calculated by dividing total area by tile area. Rounding up ensures enough tiles for cuts and breakage. Tile sizes vary, so accurate tile area is essential for precise counts.
Example
Formula: Floor area / Tile area = 20 m² / (0.5 m x 0.5 m) = 80 tiles
Select floor area and tile size units, then choose result type (rounded or exact).
Tip: Choose result type (rounded or exact) on the right before calculating.
Rounded up is typical for breakage and cuts.
Step-by-step calculation
- Enter floor area and tile size with units.
- Select result type (rounded or exact).
- Calculate to see tile count and steps for that mode.
How this is calculated
Tile count = floor or wall area divided by tile face area, plus 10% wastage (15% for diagonal or patterned layouts). Openings are subtracted first; round up to whole tiles.

FAQ
- How do I calculate tiles by hand?
- Divide floor area by tile area. Example: 20 m² / (0.5 x 0.5 m) = 80 tiles.
- What is the formula for tile count?
- Tiles = Floor area / Tile area. Use rounded up for purchasing.
- Square vs rectangular tiles
- Square tiles are easy; rectangular tiles need length x width for tile area.
- What units should I use?
- Use m² for floor area and meters for tile dimensions.
- Can I use this for a backsplash?
- Yes. Enter wall area instead of floor area for backsplash tile estimates.
