Large Format Tile: Pros, Cons, and Installation Considerations

Large-format tile is any tile that is 15” or longer on any side. However, many tiles are even larger, measuring 48” or more across. Large format tiles are popular because they have fewer grout lines, which creates a sleek and modern look. Not only that, but their larger size can make spaces feel larger than they are.

It’s easy to assume that large tiles are easier to install because you don’t need to lay out hundreds of pieces to cover an area. However, large-format tile installation can be more challenging than many homeowners realize. Let’s take a closer look at what to consider when designing a space with large tiles and what to expect from installation.

Large Format Tile Sizes

Despite the name, large-format tile isn’t a separate category of flooring. Rather, it is a design category defined purely by scale. It uses the same manufacturing processes as standard tiles. However, it produces larger tiles to create a different look and reduce the number of grout lines. Common sizes include:

• 12″ × 24″: Moderately large rectangular tiles commonly used for floors, shower walls, and kitchen backsplashes.
• 24″ × 24″: Large square tiles used most often for flooring in residential and commercial spaces.
• 24″ × 48″: Large rectangular tiles used for feature walls and flooring in larger spaces.
• 12″ × 48″: Elongated rectangular tiles used most often for flooring, with a number of wood-look options that mimic wood floors.
• 48″ × 48″: Very large square tiles used most often in large, open spaces and statement installations.

Materials: Why Large Format Porcelain Tile is So Popular

Although large-format tile is available in different materials, porcelain is the standard for most residential and commercial projects. Because porcelain is dense and strong, manufacturers can produce larger tiles that stay flat. Traditional ceramic is less dense and prone to warping in the kiln when made in larger sizes.

While large-format ceramic is available, it is generally used for walls rather than flooring. Natural stone can also be found in larger sizes, but porcelain remains the most common choice for large-format floor tile. This is because it offers an excellent balance of durability, low maintenance, and design versatility.

Challenges of Large-Format Tile

Large tiles are popular because they create a spacious, modern aesthetic and are versatile for everything from floors to backsplashes to shower surrounds. However, there are a few factors to consider before choosing large-format options.

• The surface must be properly prepared. Large tiles can’t be used to hide imperfections. Even minor variations in the substrate can result in uneven tiles, poor adhesion, or lippage.
• Installation is more demanding. Because of their size and weight, large tiles are more difficult to handle and require more precision with alignment and placement to get a professional-looking result.
• Labor can cost more. Because installation requires additional surface preparation, specialized equipment, and extra time, you may pay more for installation even when the tile itself is priced similarly to smaller tiles.
• Repairs can be challenging. Replacing a cracked tile is significantly harder with large-format options because removing such a large piece increases the risk of damaging surrounding tiles. You also have to completely remove the old mortar to create a flat surface for the new tile.

Large Format Tile Installation Considerations

When it comes to tiling, large format tiles require a different approach than smaller tiles. Fortunately, the challenges of tiling with large tiles can be addressed with planning and preparation.

1. Planning the layout. Before any work begins, it’s important to map out where each tile will be placed. Checking the layout of the tile before installation ensures that you don’t need to cut slivers of tile to fill edges after you get halfway done with the space. Likewise, it ensures that grout lines end up where you want them, which is something you have less control over with large tile.
2. Establishing a flat surface. Because each tile spans a large area, dips and high spots in the floor must be repaired or leveled before installation to provide a flat surface. This can include sanding or grinding down high areas or filling in low spots with a patch or a self-leveling underlayment compound.
3. Mortar coverage. While smaller tiles can use thinset mortar, you usually need to use large-and-heavy-tile (LHT) mortar or medium-bed mortar to provide an adequate base. This mortar is formulated to support the tile during curing rather than flatten under its weight, as thinset mortar would.
4. Minimizing lippage. With their larger size, even the smallest height difference can create a lip along one edge of the tile. Tile clips or wedges are used to hold adjoining tiles in place while the mortar cures to create a flat finished surface.

Is Large Format Tile Right for Your Space?

Every project has different priorities, from room size and layout to design and budget considerations. When choosing a tile size, keep in mind that it can look very different in a showroom than on a screen. Seeing large-format tile in person makes it much easier to compare sizes, finishes, and patterns to evaluate how each option will look in your space.
