Understanding Results

The calculator provides several key pieces of information:

Total area to be covered
Number of whole tiles needed
Extra tiles recommended for cuts and waste
Total tiles to purchase

Waste Factor Guidelines

Different layouts require different waste factors:

Simple layout (5-10%): Straight lay pattern, large rooms
Moderate layout (10-15%): Diagonal pattern, medium rooms
Complex layout (15-20%): Herringbone pattern, small rooms with obstacles

Tips for Accurate Measurements

Measure Twice: Double-check all room dimensions
Account for Obstacles: Subtract areas for fixtures and cabinets
Consider Pattern: Different patterns require different waste amounts
Include Grout Lines: Factor in grout spacing between tiles
Plan for Future: Order extra tiles for potential repairs

Frequently Asked Questions

How many extra tiles should I order?

We recommend ordering 10-20% extra depending on the complexity of your layout and your experience level. The calculator includes this in the final count.

Should I include grout lines in measurements?

Yes, the calculator accounts for standard grout line spacing in its calculations. For special patterns or wider grout lines, you may need to adjust accordingly.

What if my room isn’t perfectly rectangular?

For irregular rooms, break the space into rectangular sections and calculate each separately, then add them together. Add a few extra tiles for complex cuts.

How do I calculate for diagonal patterns?

Select a higher waste factor (15-20%) when laying tiles diagonally, as this pattern requires more cuts and generates more waste.
