Lumora Tiles

Tile Calculator

Not sure how many tiles you need? Enter your room dimensions, choose a wastage allowance for cuts and breakages, and we'll work out exactly how many full boxes to order.

  • Tiles are sold in full boxes only, so we always round up to the nearest whole box.
  • Add a wastage allowance of 10% for simple layouts, or 15% for diagonal or herringbone patterns with more cutting.
  • Box coverage (m² per box) and box price are printed on every Lumora Tiles product page if you're shopping with us.
