Scribing tile is the process of measuring a tile for cutting. It is most commonly used to measure a tile that needs to be cut to fit between an existing tile and a wall. Scribing tile eliminates the need for measuring tapes or rulers. You only need a pencil and a tile cuter to make the final cut. Scribe tile for flooring or for wall installation.
Lay one tile over the tile that is next to the wall. The tile should cover the one on the floor completely, and all four edges need to line up.
Lay a second tile on top of the loose tile you just laid down, but put the top edge of the second tile against the wall. The side edges should line up with the two tiles underneath it.
Trace the bottom edge of the top tile. The line you draw will be on the middle tile.
Remove the top tile. Remove the middle tile. Place the middle tile in your tile cutter and cut along the pencil mark you made. The bottom portion of the tile will now fit between the bottom tile and the wall.
