Common Floor Tile Sizes

  • 12×12 inch: The classic standard. Easy to install.
  • 12×24 inch: Very popular for modern look. Lays in brick pattern.
  • 18×18 or 24×24 inch: Large format. Makes small rooms look bigger. Requires very level subfloor.
  • 6×24 or 6×36 inch: Wood-look planks.

Pre-Installation Checklist

  • Subfloor: Must be rigid (no bounce) and level. Uneven floors cause large tiles to crack.
  • Thinset: Use "Large Format Field Tile" mortar for tiles larger than 15 inches on any side to prevent sinking.
  • Spacers: Use spacers (1/8" or 1/16") for even grout lines. Lippage tuning systems are recommended for large tiles.

Frequently Asked Questions

What waste percentage should I use?

For standard square layouts, 10% is industry standard. If you are laying tiles diagonally (diamond pattern) or using a herringbone pattern, bump it up to 15-20% because every edge requires a cut.

Can I use wall tile on the floor?

Generally, no. Wall tiles are thinner and slicker. They crack under foot traffic and are slippery when wet. Always check the "PEI Rating"—floor tiles should be PEI 3 or higher.
