When choosing tiles for your home, most people usually focus on the colour, finish, or pattern, but the tile size can have just as much impact on how a space looks. The size you choose will affect everything from how open a room appears to how many grout lines you’ll see across the floor. Many homes across the Gold Coast feature open-plan living areas and indoor-outdoor flow, so tile size also influences how continuous and balanced those larger spaces feel.
In this guide, we’ll look at the standard sizes commonly used in homes, which sizes tend to work best in different rooms, and the key factors to consider before making a final decision.
Standard Tile Sizes
Small Tiles
Small tiles are often used in areas where you want a bit more detail or pattern. They’re mostly seen on splashbacks, shower floors, or feature sections of walls where larger tiles wouldn’t look as balanced. Common small tile sizes include:
- 120 x 120mm
- 200 x 200mm
- 300 x 300mm
- Mosaic sheets like 25 x 25mm or 50 x 50mm
- Subway tiles such as 75 x 10mm, 100 x 200mm, or 75 x 300mm
Medium Tiles
Medium tiles are some of the most commonly used sizes in homes because they work well in many different spaces. They’re large enough to give walls and floors a cleaner look than smaller tiles, but still manageable to install around fixtures, corners, and tighter layouts.
Common medium tile sizes include:
- 300 x 300mm
- 300 x 600mm
- 450 x 450mm
- 500 x 500mm
- 600 x 600mm
Large Format Tiles
Large format tiles have become more popular in modern homes because they create a more seamless look. With fewer grout lines breaking up the surface, rooms feel more open and visually cleaner. These larger sizes are also commonly used in commercial tiling projects where wide, open floors benefit from larger tile formats.
Common large format tile sizes are:
- 600 x 1200mmm
- 800 x 800mm
- 1200 x 1200mm
Recommended Tile Sizes for Each Room
Different rooms tend to suit different tile sizes. Here’s how tile sizes are commonly used throughout the home:
Bathrooms
Bathrooms often use a mix of tile sizes depending on the area. Walls, floors, and shower zones all have slightly different requirements, so it’s common to combine two or three tile formats.
- Walls: Bathroom walls give you plenty of flexibility when it comes to tile size. Some homeowners go for classic subway tiles for a timeless look, while others choose mosaics or smaller tiles to add a bit of texture or pattern. Larger tiles are also popular in modern bathrooms because they create a cleaner look with fewer grout lines.
- Floors: Bathroom floors work best with medium-sized tiles like 300 x 300mm or 600 x 600mm. These sizes cover the space well without making installation around fixtures too difficult. When tiling in a shower, smaller mosaic tiles are often used on floors because the extra grout lines provide better grip and help with drainage.
Kitchens
Kitchens tend to be high-traffic spaces, so tile choices usually lean toward practical sizes that are easy to clean and maintain.
- Floors: Medium to large tiles such as 300 x 600mm or 600 x 600mm are commonly used for kitchen floors. They create a balanced look across the space while keeping grout lines to a manageable level.
- Splashbacks: When it comes to tiling a kitchen splashback, usually smaller tiles are used because they fit neatly between the benchtop and overhead cupboards. Subway tiles remain one of the most popular options, but mosaics and other small-format tiles can also be used.
Living Areas
Living rooms and open-plan spaces are where larger tiles really stand out. With fewer grout lines across the floor, bigger tiles can help the space feel more open and continuous, especially in modern homes with wide layouts.
- Floors: Large format tiles such as 600 x 600mm, 600 x 1200mm, or 800 x 800mm are commonly used when tiling a living room floor. These sizes help create a more seamless surface across larger open-plan spaces, where the living space flows into dining or outdoor areas.
- Walls: Tiles are less common on living room walls, but they’re sometimes used as feature areas for fireplace surrounds or statement walls. Larger tiles are also often chosen here because they create the same clean, modern look.
Outdoor Areas
Outdoor tiles work best when they visually connect with the flooring inside the home. Using a similar tile size helps create a smoother transition between indoor and outdoor areas, especially when the spaces flow directly into each other through large doors or open-plan living areas.
- Floors: Medium to large format tiles such as 600 x 600mm or 600 x 1200mm are commonly used in patios and outdoor entertaining areas. These sizes work well in larger spaces and give the area a more open look. Just make sure the tiles you choose have the right slip rating, especially if the area gets wet. This is particularly important when tiling around swimming pool areas where water exposure is constant.
Factors to Consider When Choosing Tile Size
While some tile sizes naturally suit certain rooms, there are a few practical factors that can help guide your decision.
Room Size and Layout
Start by looking at the overall size and shape of the room. Larger tiles suit wide, open areas because they cover more floor space and create a more continuous surface. In smaller rooms with lots of fixtures or corners, medium tiles can sometimes be easier to work with because they require fewer awkward cuts. This is where experienced professional tilers can help plan the layout so the tiles fit the room properly and tricky cuts are kept to a minimum.
Grout Lines and Maintenance
Tile size directly affects how many grout lines will appear across the surface. Smaller tiles naturally create more grout joints, which can add texture but will require a little more cleaning over time. Larger tiles reduce the number of grout lines, which many homeowners prefer for a simpler look and less upkeep.
Visual Style
Tile size can change the overall character of a room. Larger tiles are often used when homeowners want the floor to feel more open and less visually broken up. Smaller tiles, mosaics, or patterned layouts are used when it’s part of the design, such as feature sections or decorative layouts. Design choices like tile size are often considered alongside colour, texture, and the type of tile used, such as using natural stone or porcelain for the space.
Slip Resistance
Wet areas need tiles that provide a reliable grip underfoot. Shower floors are a good example. Mosaic tiles are commonly used here because the extra grout lines provide better grip and make it easier to create the slope toward the drain. Larger tiles can still be used on bathroom floors or outdoor areas, but they rely more on the tile’s surface texture for slip resistance.
Final Thoughts
Tile size is one of the choices that can quietly shape how a space looks once everything is installed. From small mosaics and subway tiles to medium formats and large format tiles, each size tends to suit different parts of the home. By thinking about the room layout, how the space will be used, and the overall style of the home, it becomes much easier to narrow down the tile size that will work best.
