Tile Calculator
Calculate exactly how many tiles you need for floors, walls, and backsplashes. Includes waste factor for cuts, breakage, and complex layouts.
About the Tile Calculator
The Tile Calculator is a precise tool for determining the number of tiles required for any tiling project. Whether you are installing ceramic tiles on a bathroom floor, subway tiles on a kitchen backsplash, or porcelain tiles on a patio, this calculator provides accurate tile counts and material estimates. It accounts for tile size, area dimensions, and a configurable waste factor to ensure you order the right amount.
Ordering too few tiles causes project delays and the risk that replacement tiles may not match the original batch. Ordering too much wastes money. This calculator strikes the perfect balance by calculating the exact coverage needed and adding a sensible waste percentage for cuts, breakage, and future repairs. It supports any tile size, from small mosaic tiles to large-format porcelain slabs.
The tool is perfect for homeowners planning DIY tile installations, contractors estimating material costs for bids, and interior designers specifying materials for client projects. It provides results in both individual tiles and total square footage for easy ordering.
How to Use the Tile Calculator
Calculate your tile needs in these steps:
- Measure the length and width of the area to be tiled in feet.
- Enter the tile dimensions in inches (e.g., 12x12 for standard tiles).
- Set the waste percentage based on your layout complexity (10-15% recommended).
- Click Calculate to see the total number of tiles and total square footage needed.
For diagonal installations or rooms with many obstacles, increase the waste factor to 15-20%. Always purchase all tiles from the same lot to ensure color consistency. Keep a few extra tiles for future repairs.
