Estimate how many tiles, boxes, and how much material you may need for a floor, wall, bathroom, kitchen, backsplash, or remodeling project.
Enter the room size, tile size, waste percentage, tiles per box, and price per box to get a quick planning estimate before buying tile.
Calculator results are estimates only. Confirm final quantities with your installer, supplier, or project documents before purchasing material.
The tile calculator compares the total room area to the size of each tile. It then adds waste for cuts, broken pieces, layout adjustments, and extra material.
The basic formula is:
Tiles needed = room area ÷ tile area
For better planning, most tile projects include extra material for waste, cuts, corners, patterns, and future repairs.
A common planning range is 10% waste for simple layouts. Larger rooms, diagonal layouts, patterned tile, small cuts, or complex edges may require more. Always confirm final quantities before purchasing material.
For a 12 ft by 10 ft room using 12 inch by 12 inch tile, the room area is 120 square feet. Since each tile covers 1 square foot, the base estimate is 120 tiles. With 10% waste, the estimate becomes 132 tiles.
This calculator provides estimates only. Actual tile needs can vary based on layout, pattern, grout spacing, cuts, breakage, tile size variation, room shape, and installation conditions. Always verify final quantities with your installer, supplier, or project plans before purchasing tile.
