How to Cut a Ceramic Tile

Cutting ceramic tiles may sound scary, but it is actually surprisingly easy. The tool you use will depend on what sort of cut you are doing and how many tiles you plan on cutting. If you just have to cut a few tiles, a glass cutter will suffice. If you need to cut more tiles, however, a tiling tool or a wet saw might be more convenient. Knowing how to cut tiles yourself can save you a lot of money, and ensures that your tiles come out precisely the way you want them to.

Use a pencil and a square to measure and mark your tiles. A square is a special ruler shaped like a right angle. Align the horizontal edge of the square with the bottom edge of the tile. Use the vertical edge of the square and a pencil to draw your guideline.
- This method is better suited to small jobs where you just need to cut a few tiles. It is not suitable for cutting corners or curves.
A workbench or plywood would work the best for this. Move the square off to the side so that it is right next to your marked line. This will allow you to cut right along the line without cutting into the square.^{[1]XResearch source}

Score the tile with the glass cutter. Press down on the tile with the glass cutter, then drag it across the line that you drew, using the square as a guide. You may have to score the tile a few times in order to make a shallow cut.^{[2]XResearch source}
- If you can't find a glass cutter, try a carbide tipped pencil instead.^{[3]XResearch source}
4
Snap the tile over a wire hanger. Place the tile on top of a wire hanger. Make sure that the hanger is aligned with the line that you scored. Next, press down on the un-scored edges of the tile until it snaps.^{[4]XResearch source}
- if you scored from left-to-right, press down on the top and bottom edges, and vice versa.
- If you scored the tile close to the edge, snap off the thinner side with tile nippers.^{[5]XResearch source}
You can do this by rubbing the cut edge of the tile back and forth across a brick or some concrete. This will buff away any roughness, much like sandpaper would on a block of wood.^{[6]XResearch source}

Measure and mark your tile with a square and a pencil. A square is a ruler shaped like a right angle. Align one edge of the square with one edge of your tile. Use a pencil and the other edge to draw your guideline.
- This method is great if you have a lot of tiles to cut. It's also suitable if you need to cut a lot of surface area, such as corner-to-corner cuts (as opposed edge-to-edge).
Set the square aside and set the tile into the tile cutter. Push the tile right up against the fence, and make sure there is no debris preventing the tile from touching the fence. Make sure that the line that you drew is right under the scoring wheel.^{[7]XResearch source}
Use smooth, even pressure. Gently press down on the handle of the cutter, then slide the wheel part across the tile. Hearing a scratching noise is nothing to worry about, it just means everything is going as planned and the tile is being cut.^{[8]XResearch source}
Move the handle away from the edge of the tile so that the breaking feet land on top of the tile. Gently press down on the handle again to lower the breaking feet and snap the tile.^{[9]XResearch source}
Set up a jig that’s composed of 2 1-by-4s. Separate the 1-by-4s with a strip of wood that's the same thickness as your tile. Make sure that the scored line is level with the edge of your jig set-up. Press down on the tile to create a clean break.^{[10]XResearch source}
Rub the cut edge of the tile back and forth across a brick until the roughness is gone. If you don’t have a brick handy, concrete will also work.

Using a Wet Saw for Straight and Corner Cuts

1
Measure and mark your tiles where you want to cut them. Use a measuring square to determine how much you need to cut off and make a strong mark with a pencil or where you would like to cut so the water doesn’t erase the mark. Then make the marks in any direction you'd like, such as horizontal, vertical, or even diagonal.
- This method is suitable for bigger jobs that involve a great amount of tile.
- You can also use wet saws to cut tile trimmings with a bullnose or quarter-round shape.^{[11]XResearch source}
2
Set up the wet saw according to the saw's instructions. Each wet saw will be a little different, so be sure to follow the instructions closely. In most cases, you will need to fill the tub with water and turn the saw on.^{[12]XResearch source}
- Make sure the water level doesn’t get too low, and be sure to replace it when it gets dirty so the saw operates properly.
3
Cut the tile according to the saw’s instructions. Each saw will be a little different, so read the instructions carefully. For the cleanest cut, avoid pushing or forcing the tile into the saw. Instead, gently guide the tile towards the saw, and let the saw do the cutting for you.^{[13]XResearch source}
- Make sure that the water is covering the blade when cutting.
4
Smooth down any roughness with a brick. Even if you took extra steps to ensure the cleanest of cuts, there may be some roughness on the cut edges. If this happened to you, simply rub the cut edge of the tile across a brick or a piece of concrete a few times.
- Avoid using a brick or piece of concrete with jagged edges, as this could break the tile.

Using Tile Nippers for Curves

1
Draw a curved line with a pencil where you want to cut the tile. Don’t be afraid to use French curves, cans, lids, and other round objects as a template. If the area you will be cutting is far from the edge of the tile, consider cutting the tile down using one of the above methods first.
- This method will require you to cut the tile away, bit by bit, until you reach the line that you drew.
Place them close to the edge of the tile—even if your curved line is further in. Break off small pieces of tile at a time. If you break off too much at one time, you will risk breaking the tile.
Squeeze down on the handle of the tile nippers to get a good grip on the tile. Snap the piece off of the tile.
Work your way back and forth across the tile in narrow rows. Break off smaller pieces the closer you get to the line for more precision.^{[14]XResearch source}
Rub the cut edge of the tile back and forth across a smooth brick or piece of concrete. Rock the tile while doing so to ensure that the edge gets smoothed evenly.

Ceramic can be kind of tricky to drill into since it tends to be very sensitive. If you're drilling into it, make sure that you're using an abrasive drill bit that's designed specifically for ceramic. Also, keep the drill bit wet a little while you're drilling to keep the ceramic from getting too hot. Finally, make sure that you're working really slowly. If you go too fast, you're more likely to break the ceramic tile.

Tips

If the tile is glazed, make your mark on the glazed side.^{[15]XResearch source} If the mark is not showing up, try a permanent marker. You can wipe it off later with rubbing alcohol.

Wet saws and tile cutters can get expensive and take up a lot of room. If this is a one-time job, consider renting from your local hardware store instead.^{[16]XResearch source}

As an alternative, use a grinder with a diamond tile cutter wheel to cut the tile. Create a pencil line where you want to make the cut, then use the grinder to lightly score the line. Then, pass back and forth over the score mark until the tile is cut.
