Tile Pattern Waste Calculator
Compare tile order quantities for common installation patterns using the same project area and tile size. The tool makes each pattern's planning allowance visible instead of pretending one waste percentage applies universally.

Pattern comparison
Why pattern waste is not one fixed number
Tile waste is determined by how the tile grid meets boundaries. A straight grid can reuse many cuts when dimensions cooperate, while a running bond or herringbone pattern changes the cut rhythm and the ability to reuse offcuts.
How the comparison works
The calculator first determines a mathematical tile minimum from area. It then applies an illustrative allowance to each pattern. These assumptions can be replaced with a common custom allowance when you have project experience or a measured takeoff.
Why herringbone deserves separate treatment
Herringbone introduces repeated angled cuts at boundaries and may generate many small triangular or trapezoidal remnants. Those remnants are sometimes reusable, but not necessarily in the required locations.
Practical takeaway
Use the comparison to screen quantities early. For a final order, use the actual setting-out drawing or a detailed takeoff, especially when the tile is expensive or the pattern is strongly directional.
Frequently Asked Questions
Are the pattern percentages standards?
No. They are transparent planning assumptions.
Can I replace them?
Yes, by selecting the custom allowance option.
Can one pattern use fewer tiles?
Yes under the model, because each pattern uses a different assumed cutting allowance.
Does tile size matter?
Yes, because tile area controls the mathematical minimum and boundary behavior.
