Understanding Tile Calculations

Accurate tile calculations are crucial for any tiling project. Here's what you need to know:

Tile Sizes and Coverage

Tiles come in various sizes, from small mosaics (2x2 inches) to large format tiles (24x48 inches or larger). The size you choose affects:

  • Installation complexity
  • Room appearance (larger tiles can make small rooms look bigger)
  • Amount of grout lines
  • Overall cost and waste

Grout Gap Considerations

Proper grout gap sizing is essential for:

  • Wall tiles: typically 2-3mm
  • Floor tiles: usually 3-5mm
  • Natural stone: may require larger gaps (3-6mm)
  • Outdoor applications: often need 4-6mm gaps

Waste Factor Guidelines

Include extra tiles for:

  • Simple layouts (straight pattern): 10%
  • Diagonal patterns: 15-20%
  • Complex patterns/cuts: 20-25%
  • Future repairs: Additional 5%
