How to use the Tile Quantity Calculator
- Enter the room length and width.
- Enter the tile size and the joint.
- Set wastage and read how many tiles to order.
Questions
Does the joint add area?
Yes. Each tile is counted on a pitch of tile plus joint, so a wider joint means fewer tiles.
What about a patterned layout?
The count is for a straight grid. Cuts and a diagonal layout need the wastage you allow for them.
