Complete Guide to Tile Calculator

This guide will help you accurately calculate tile quantities for walls, floors, and other surfaces, including support for diagonal layouts.

Measuring Surface Area

Measure the length and width of the surface to be tiled:

  • Walls: Measure height and width
  • Floors: Measure length and width
  • Irregular surfaces: Break into rectangles and calculate each separately

Understanding Tile Sizes

Common tile sizes:

  • Small tiles: 10×10cm to 20×20cm
  • Medium tiles: 30×30cm to 40×40cm
  • Large tiles: 60×60cm and above

Always verify actual tile dimensions from your supplier.

Waste Factors

Waste factors account for:

  • Cuts and trimming
  • Pattern matching
  • Breakage during installation
Standard waste:
  • Straight layout: 5-10%
  • Diagonal layout: 10-15%
  • Complex patterns: 15-20%

Diagonal Layouts

Diagonal layouts require more waste due to:

  • Increased cutting at edges
  • Pattern alignment challenges
  • More complex installation

The calculator automatically increases waste factor for diagonal layouts.

Best Practices

  • Always measure actual tile dimensions
  • Account for grout lines in calculations
  • Order 10-15% extra for repairs
  • Keep tiles from same batch for color consistency

Common Mistakes

  • Not accounting for diagonal layout waste
  • Using wrong tile dimensions
  • Forgetting grout space
  • Not ordering extra for repairs

Conclusion

Accurate tile calculations prevent shortages and reduce waste. Always verify measurements and tile dimensions before ordering.
