Tile Calculator
Our tile calculator makes it simple to calculate how many tiles you need per square meter, including extra for cutting and wastage.
Note: This calculator provides an estimate of tiles needed for your project. Actual requirements may vary based on room shape, pattern layout, tile cuts, and obstructions. Always purchase 10-15% more tiles than calculated to account for cutting waste, breakage, and future repairs.
What Is a Tile Calculator?
A Tile Calculator helps you work out how many tiles you need based on your room size, tile dimensions, and waste allowance. Instead of estimating and hoping you bought enough, the calculator gives accurate results in square meters or square feet.
If your building project also includes driveways or pathways, you can smoothly continue planning using the paving bricks calculator without jumping between unrelated tools.
How a Tile Calculator Works
A tile calculator uses three main inputs:
- Area size – the total length and width of the surface
- Tile size – measured in mm, cm, or m²
- Wastage allowance – usually between 5–15%
- Grout spacing – optional but important for accurate spacing
Once these numbers are entered, the tool automatically works out:
- Total number of tiles needed
- Total number of boxes required
- Square meters covered
- Extra tiles recommended for cuts and breakages
This makes planning easier and ensures your budget is accurate.
Tile Calculator for Different Projects
Every tiling project is different. That’s why people search for things like tile calculator m², tile calculator square meters, or tile calculator South Africa—each project requires a slightly different method of measuring.
Below are the most common use cases.
Floor Tile Calculator
A floor tile calculator helps you determine how many tiles you need to cover indoor or outdoor floors. Floors often require more wastage allowance because of cuts around cupboards, corners, and skirting.
Wall Tile Calculator
Walls normally have fewer obstructions, but height and alignment matter. A wall tile calculator makes sure you get the correct number of tiles for vertical spaces such as bathrooms, splashbacks, and showers.
Roof Tile Calculator
Many homeowners also need a roof tile calculator to estimate tiles for pitched roofs. Roofs require slightly different measurements because pitch, overlap, and spacing affect the number of tiles used.
If you need a dedicated tool for roofing, you can also explore our specialised pages such as:
Tile Calculator in Square Meters (m²)
Along with tile quantity, you need to know how much adhesive and grout to buy. Our calculator also shows:
- Tile adhesive (kg) per m² based on trowel size
- Grout (kg) based on tile joint width
This makes sure you have everything ready before starting your project.
Conclusion
A tile calculator is one of the most reliable tools for planning any tiling project. It ensures accuracy, saves money, and removes the guesswork from measuring your area. Whether you’re working with floors, walls, mosaics, or even roofing materials, the calculator provides quick and precise results.
