What Is a Tile Calculator?
A tile calculator is a tool that helps you determine the precise number of tiles needed for a floor, wall, or backsplash project. By entering the area to be tiled and the dimensions of a single tile, it calculates the total material required, including a crucial waste factor for cuts and mistakes. This ensures you buy the right amount of tile for your job.
How to Use This Calculator
- Enter the total square footage of the area you plan to tile.
- Input the width and length of a single tile in inches.
- Specify your desired grout line width.
- Set a waste factor (10% is standard, 15-20% for complex patterns).
- Click "Calculate" to see the total number of tiles needed.
Understanding Your Tile Calculation
- Tiles Needed: This is the total number of individual tiles you should purchase. This number includes the waste factor.
- Total Material Required: This is the total square footage of tile to buy. It's useful for comparing costs if tiles are priced per square foot.
