Tile Cutting Waste Calculator

Cutting creates waste; know it early always. Choose tile size, layout, and complexity factors easily. Get tiles, boxes, and waste totals in seconds here.

Enter Project Details

Choose how you will enter dimensions.
Leave blank if using total area.
Rectangular estimate for garden surfaces.
Use when the shape is not rectangular.
Common sizes: 200, 300, 600.
For square tiles, use the same value.
Included in module coverage estimation.
Pattern changes typical cut waste.
Corners and borders increase offcuts.
Adds 0.5% waste each, capped at 5%.
Use for fragile tiles or tricky cuts.
Spare tiles for future repairs.
Used for estimating boxes to buy.
Leave blank if you price by box.
Boxes calculated using tiles-per-box.

Tip: For irregular garden patios, fill “Total area override”.

Example Data Table

Surface (m²) Tile (mm) Pattern Complexity Obstacles Waste % Tiles to Order Boxes (10/box)
20.000 300 × 300 Straight Simple 0 10.0% 245 25
20.000 300 × 300 Diagonal Medium 2 19.0% 266 27
35.000 600 × 600 Herringbone Complex 5 32.5% 131 14
Examples are illustrative. Real waste varies with cutting strategy.

Formula Used

  • Surface area: A = L × W, or use your area override.
  • Unit conversion: ft² × 0.092903 = m².
  • Tile module: (tile length + grout) × (tile width + grout).
  • Tiles without waste: N = ceil(A ÷ module area).
  • Total waste %: pattern + shape + obstacles + extra allowance.
  • Tiles to order: T = ceil(N × (1 + waste%)) + extra tiles.
  • Boxes: B = ceil(T ÷ tiles per box).

  3. Enter tile dimensions and the expected grout gap.
  4. Pick the layout pattern that matches your design.
  5. Set shape complexity and obstacle count for cut losses.
  6. Add extra waste or spare tiles for future repairs.
  7. Enter tiles per box and optional pricing information.
  8. Press Calculate to see results above the form.
  9. Use Download CSV or Download PDF for records.
