About Tile Calculator

Our Tile Calculator helps you estimate the number of tiles needed for your flooring, wall, or other tiling projects. By accounting for tile size, area dimensions, gap size, and waste factor, this tool provides accurate calculations to help you purchase the right amount of materials.

How to Use

1. Enter the dimensions of your tiles (length and width)
2. Enter the dimensions of the area to be covered
3. Specify the gap size between tiles (grout lines)
4. Adjust the waste factor based on your project complexity (10-15% is typical)
5. Optionally, add box size and pricing information
6. Click Calculate to get the results

Understanding Gap Size

Gap size (grout line) is important for proper tile installation. It allows for expansion and contraction of tiles and helps with alignment. Typical gap sizes:

• Floor tiles: 1/8 to 1/4 inch (3-6 mm)
• Wall tiles: 1/16 to 1/8 inch (1.5-3 mm)
• Natural stone: 1/8 to 1/4 inch (3-6 mm)

Waste Factor

Waste factor accounts for tiles that may be cut, broken, or otherwise unusable. The recommended waste factor varies by project:

• Simple rectangular room: 5-10%
• Room with angles or curves: 10-15%
• Complex pattern or diagonal layout: 15-20%

Tile Installation Tips

• Always order extra tiles to account for waste and future repairs
• Check all tiles for color and consistency before installation
• Start from the center of the room and work outward
• Use spacers to maintain consistent gap size
• Allow tiles to acclimate to room temperature before installation

Common Tile Sizes

• Mosaic: 1x1 inch, 2x2 inch
• Small: 4x4 inch, 6x6 inch
• Medium: 8x8 inch, 12x12 inch
• Large: 16x16 inch, 18x18 inch, 24x24 inch
• Plank: 6x24 inch, 6x36 inch
