About This Tool
Tile Calculator estimates how many tiles are needed to cover a floor or wall area, accounting for tile size, pattern direction, and a waste percentage for cuts and breakages. It prevents costly shortfalls during a tiling project.
When to Use It
Use this before buying tiles for a bathroom, kitchen, or floor project to ensure you purchase the right quantity, when planning a herringbone or diagonal pattern that increases waste, or when budgeting material costs.
How to Use
- Enter the area dimensions in metres.
- Enter the tile size.
- Select the tile pattern.
- Set the waste percentage, typically 10 to 15 percent.
- Click Calculate to see the number of tiles needed.
Frequently Asked Questions
How much extra should I buy for waste?
Add 10 percent for straight patterns, 15 percent for diagonal or herringbone layouts, and 20 percent for very small or irregularly shaped areas.
Should I include grout joints in the calculation?
Yes. The calculator accounts for the grout joint width when computing tile coverage, which slightly reduces the number of tiles needed compared to a tile-only calculation.
What if I need to match an existing tile pattern?
Purchase an additional 5 to 10 percent above the calculated amount to ensure you have matching tiles for repairs or replacements in the future.
