Tile format — the size and shape of a tile — is one of the most important decisions in any tiling project. It can influence how spacious a room feels, how the finished surface looks, and how much time, material and labour are required for installation. Rather than choosing tile size after deciding on colour and finish, it is better to consider the format at the beginning of your project.
Small Tiles for Small Spaces
It is a common misconception that small rooms always need small tiles. In fact, using too many small tiles can create more grout lines, making a compact space appear visually busy.
Large-format tiles can often make a small bathroom or room feel more open, particularly when they are used across large areas or from floor to ceiling. Fewer grout lines create a cleaner, more continuous surface and can help the space appear larger.
Choosing the Right Tile Format for the Application
Different tile formats work better for different areas of the home. Mosaic tiles are well suited to curved surfaces, shower floors and feature areas where detailed patterns are desired.
Subway tiles are a popular choice for kitchen splashbacks and bathroom walls, offering a classic and versatile look.
Large-format tiles, generally 600mm and above, are particularly effective in open-plan living areas, spacious bathrooms and larger floors where a seamless, contemporary appearance is preferred.
How Tile Layout Patterns Change a Room
The way tiles are installed can significantly influence how a room looks and feels. A brick-bond or offset pattern can emphasise the horizontal direction of a room, helping it appear wider.
A straight stack layout creates a clean, structured and contemporary appearance, while herringbone and chevron patterns introduce movement and visual interest.
A diagonal layout can also make a room appear more spacious by directing the eye towards the corners rather than the walls.
Consider Tile Waste and Installation Costs
Tile size and layout can also affect material waste and installation costs. Larger tiles may result in more offcuts when working around corners, recesses, drains and other awkward areas.
Diagonal layouts generally require additional material, so it is worth allowing approximately 15–20% extra tiles depending on the room and installation pattern.
More detailed layouts, such as herringbone, chevron and fan patterns, typically require greater installation skill and can take longer to complete. This may increase labour costs.
By considering tile format, layout, waste and installation requirements from the beginning, you can choose a tile solution that works both aesthetically and practically for your space.
