How to Cut Tiles with a Glass Cutter?

Draw a straight line for your cut using a square. You can use a specific marble tile marker or a crayon. Set the square about 1⁄4 inch (0.64 cm) below the line, allowing room for your pencil or marker to line up perfectly with your measurement. You can buy a square at a hardware store or from an online retailer. If you don’t have a square, you can use anything that has a straight edge.

Score the tile along the cut line with the glass cutter. Firmly press down on the glass cutter as you drag it along your marked line. The idea is to just cut partially through the glazed rustic tile. You don’t want to push hard enough that you cut all the way to the bottom of your ceramic tile. Scoring should sound like a scratching or crackling noise.

You can buy a glass cutter at a craft store or hardware store for around $10. It’s a small hand tool with a sharp blade that cuts through glass and other hard materials when you press down and drag. Set a square along the cut line during this step to help guide the glass cutter.

Place a wire clothes hanger underneath the scored cut on a flat surface. A sturdy surface like a workbench or thick piece of plywood is best. Line up the long wire part of the hanger with the scored line. If you don’t have a wire hanger, you can use a thick piece of regular wire. It just needs to be thin enough to run along the scored line.

Break the tile along the score line by pressing down on each side. Use your palms to push gently to avoid splintering the wall tile, but use enough pressure to cleanly break the polished tile. The wire hanger elevates the tile slightly off the table so the sides of the tile size have room to snap off.

Wearing safety glasses when you break the tile will protect you from any pieces that might fly off. The spots tile should snap very easily. If it doesn’t, you may need to score it again. If you have a rough cut edge, you can sand it on a slab of concrete or a brick to smooth it out.
