A manual tile cutter suits most ceramic tiles and softer porcelain, while an electric tile cutter is needed for denser, thicker or textured porcelain. Scribes and nippers cover the smaller, more awkward cuts neither tool handles well, such as around a plug socket or door frame. This guide compares all three, includes a scoring-wheel size chart, a step-by-step process for manual and electric cutting, and a dedicated comparison of porcelain tile cutters versus ceramic tile cutters.

Tile Cutter Types Compared
Three tools cover most tile cutting jobs: a manual cutter, an electric cutter, and a scribe or set of nippers. The table below sets out which suits which job.
| Tool | Best For | Typical Tile | Cut Type |
| Manual tile cutter | Straight cuts, brick bond effects, resizing to fit a corner | Ceramic, and softer or thinner porcelain | Straight lines |
| Electric tile cutter | Denser, thicker or textured tiles; bevelled or unusual shapes | Porcelain, natural stone | Straight or bevelled |
| Scribe | Smaller ceramic tiles such as metros | Ceramic | Straight lines |
| Nippers | Awkward or irregular edges | Ceramic and porcelain | Irregular, nibbled edges |
Scoring Wheel Size Guide
Common scoring wheel sizes include 6mm, 8mm, 10mm, 18mm and 22mm, though the correct wheel for a specific job depends on the cutter, the wheel’s own design, and the tile’s thickness and surface texture. The table below gives a general starting point; always follow the cutter and scoring wheel manufacturer’s own recommendation for a specific product rather than treating these figures as a universal rule.
| Wheel Size | Suited To |
| 6mm | Ceramic wall tiles |
| 8mm | Ceramic wall tiles, ceramic floor tiles, and smooth porcelain |
| 10mm | Ceramic floor tiles |
| 18mm | Textured and structured porcelain |
| 22mm (extreme) | Hard, textured and structured porcelain, and 20mm porcelain |
How to Use a Manual Tile Cutter
A manual tile cutter scores the tile’s glaze, then snaps it cleanly along that score line. Many manual cutters can handle a range of tile types by fitting the appropriate scoring wheel, provided the tile stays within the cutter’s own maximum cutting length and thickness; the wheel is matched to the material and surface, not a way of extending what size of tile the cutter can physically handle.
- Measure and mark the cut line. Measure twice before marking, since a cut tile cannot be uncut; keep a few spare tiles in case of a mistake.
- Fit the correct scoring wheel for the tile’s material and thickness, using the size guide above.
- Place the tile face up in the cutter and align it against the guides so the cut runs perfectly straight.
- Score the tile in one pass, running the wheel from the bottom of the tile to the top with enough pressure to score through the glaze.
- Snap the tile by pulling the handle down firmly and evenly along the score line.
For the best cosmetic result, position the cut edge toward the wall, corner or trim, and keep the factory edge facing outward next to the neighbouring tile.
How to Use an Electric Tile Cutter
An electric tile cutter, often called a wet tile saw, uses a water-cooled diamond blade to cut denser, thicker tiles that a manual cutter cannot manage cleanly. These are most commonly used for porcelain, since porcelain is denser and stronger than ceramic, and they can produce cuts a manual cutter categorically cannot, such as a bevelled edge, an L-shaped cutout, or a mitred corner. For a curved or irregular cut, such as fitting a tile around a basin pedestal or toilet, a wet saw typically makes the straight sections of the cut, with nippers or another suitable diamond cutting tool used to refine the curved part afterward.
- Measure and mark the tile as with a manual cutter.
- Check the blade guard is fitted and the water reservoir is filled before starting; the blade needs a constant flow of water to stop it overheating.
- Line the marked tile up with the blade and feed it slowly and securely along the cut line.
- Keep the tile pressed down throughout the cut, since the blade’s movement can cause it to lift.
- Work outdoors or in a well-ventilated space, since the process is wet and can get messy.
Scribes and Nippers
A tile scribe works in a similar way to a manual cutter but uses a secure metal ruler and a handheld scoring tool instead of a fixed cutting rail. Measure and mark the tile, score along the line against the ruler, then snap the tile across the back edge of the scribe. This method suits smaller ceramic tiles, such as metro tiles, better than larger formats.
Nippers work like a pair of pliers and are designed for nipping small sections from a tile’s edge, rather than making a full straight cut. They suit awkward or irregular shapes, such as fitting a tile around a door frame or a plug socket, where a straight cutter cannot follow the shape needed.
Porcelain Tile Cutter vs Ceramic Tile Cutter
The right cutter depends on the tile’s material, thickness and surface texture together, not on ceramic versus porcelain as a simple either/or rule. A ceramic tile cutter is usually a manual cutter or scribe, while a porcelain tile cutter is more often an electric cutter, but that pattern is a starting point rather than a fixed rule. Ceramic is softer and less dense than porcelain, so a manual cutter’s scoring wheel scores through the glaze easily and the tile snaps cleanly along that line.
Porcelain is fired at a higher temperature and is significantly denser, which makes it more resistant to a simple score-and-snap cut, particularly once it is thicker than around 10mm or has a textured, structured surface. A smooth, thinner porcelain tile can often still be cut with a manual cutter fitted with the correct scoring wheel and within the cutter’s rated capacity, but a thicker or heavily textured porcelain tile generally needs an electric wet saw to produce a clean edge without cracking or chipping.
Buying a Tile Cutter: What to Look For
The right tile cutter to buy depends on the size of the project, the tile material, and how often it is likely to be used again. For a single room using ceramic tiles, a manual cutter with an interchangeable scoring wheel covers most cuts at a lower cost than an electric model. For a project using porcelain, natural stone, or a mix of tile formats and shapes, an electric wet saw is a better investment, since it handles denser material and unusual cuts a manual cutter cannot.
Check the cutter’s maximum tile size and thickness rating against the tiles being used, and where a project is a one-off, hiring an electric cutter is often more cost-effective than buying one outright. Cut quality is worth weighing alongside price too: a cheap cutter that chips or cracks a high proportion of tiles can end up costing more in wasted material than a better-quality tool would have in the first place.
Safety When Cutting Tiles
Cutting tiles carries a real risk of sharp shards and flying debris, so basic protective equipment is worth using regardless of which cutter is chosen. Wear protective gloves and safety goggles when cutting any tile, since shards can travel further than expected, and handle a freshly cut piece carefully afterward, since the cut edge itself can be extremely sharp. When using an electric wet saw, add appropriate hearing protection, always keep the manufacturer’s blade guard fitted, keep hands well clear of the blade rather than guiding the tile from close range, and keep the electrical connection protected from the water used to cool the blade. Use the cutter exactly as the manufacturer specifies, and keep the work area controlled and clear of anyone not involved in the cut.
Cutting porcelain and natural stone can release fine, silica-containing dust, which is a genuine respiratory hazard if inhaled over time. Wet cutting, where the blade runs cooled and lubricated by water, controls this dust far better than cutting dry, which is one of the main reasons an electric wet saw is generally preferred over a dry cutting method for porcelain and stone. Where dry cutting cannot be avoided, appropriate respiratory protection and good ventilation both help reduce exposure.
Choosing the Right Tile Cutter
Match the cutter to the tile rather than assuming one tool handles every job. A manual cutter with the right scoring wheel covers most ceramic and many porcelain tiles for a straightforward straight cut, an electric cutter takes over for denser porcelain, natural stone and bevelled or unusual shapes, and a scribe or nippers finish off the smaller and more awkward cuts neither tool manages well.

Frequently Asked Questions
What is the best tile cutter for porcelain?
An electric tile cutter with a water-cooled diamond blade is generally the best choice for porcelain, particularly for thicker or textured tiles. A smooth, thinner porcelain tile can sometimes still be cut with a manual cutter fitted with a suitable scoring wheel.
Can I use a manual tile cutter on ceramic tiles?
Yes, a manual tile cutter is the standard tool for ceramic tiles, since ceramic scores and snaps cleanly with the right scoring wheel. Manual cutters are also generally more affordable than electric cutters for a straightforward ceramic tiling project.
Do I need an electric tile cutter for every project?
No, an electric tile cutter is only needed for denser, thicker or textured tiles that a manual cutter cannot cut cleanly. A standard ceramic tiling project can usually be completed with a manual cutter alone.
What scoring wheel size do I need for my tiles?
As a general guide, 6–8mm suits most ceramic wall tiles, 8–10mm suits ceramic floor tiles and smooth porcelain, and 18–22mm suits textured or structured porcelain, though the exact wheel depends on the specific cutter and wheel design. Checking the cutter and scoring wheel manufacturer’s own recommendation is more reliable than treating any general chart as a fixed rule.
How do I cut a tile around a toilet or basin?
For a curved or irregular cut around a toilet or basin pedestal, an electric wet saw can make the straight sections of the cut, with tile nippers or another suitable diamond cutting tool used to refine the curve. A straight manual cutter or scribe cannot follow a curved or irregular line on its own.
