Enter the room and tile size. The layout sets the waste, so a herringbone floor doesn't get quoted like a straight grid.
How it works
Area ÷ the area of one tile, plus 10% for grid or brick, 15% for diagonal and 20% for herringbone. Boxes round up.
Before you order
- Dry lay a row to avoid a sliver of tile along the most visible wall.
- Keep spare tile from the same lot for future repairs.
- Mix tiles between boxes so shade differences spread out.
Common questions
How much extra tile should I order?
About 10% for simple layouts, more for diagonal and herringbone. Very large tile can need more because one bad cut costs a whole piece.
Do grout joints change the count?
Slightly, but not enough to matter on most floors. The nominal size is close enough to plan with.
