Large Format Tile: 6 Key Things to Know Before You Buy

Large format tiles have taken over Pinterest boards and showroom displays—and for good reason. Their clean lines, minimal grout joints, and expansive look can instantly modernize a space. But before you fall in love with that stunning 24×48 porcelain tile, there are a few key things to consider to make sure it’s the right fit for your project.

1. Understand What Counts as “Large Format”

Any tile with at least one side longer than 15 inches is technically considered large format. Common dimensions include 24×24, 24×48, 32×32, and even massive porcelain panels that come as large as 48×110. The size you choose impacts installation method, subfloor prep, and overall aesthetic.

2. Subfloor Prep Matters More Than Ever

Large format tiles demand a level, properly prepared substrate. Any unevenness in your subfloor can lead to lippage (where one edge of a tile sits higher than the one next to it), which is especially noticeable with bigger tiles. A skilled installer will use leveling systems and may recommend additional prep work to ensure a flat finish.

3. You’ll Use Less Grout—But It Has to Be Done Right

One of the appeals of large format tile is the sleek look of fewer grout joints. While this can make cleaning easier and create a seamless design, it also means grout lines must be precise and level. Selecting the right color grout and spacing (typically 1/16” to 1/8”) is key to achieving the look you want.

4. Consider the Layout Carefully

Large tiles can visually expand a room, but the layout plays a big role in how the final result feels. Vertical stacks on shower walls can elongate the space, while a horizontal layout on floors may make a narrow room feel wider. A designer can help you find the best layout for your room’s shape and lighting.

5. Not All Spaces Are a Fit

While large format tile works beautifully in open spaces like living rooms, bathrooms, and kitchens, it might overwhelm smaller areas like powder rooms or backsplashes. For tight spaces or irregular layouts, a smaller tile or a combination of sizes might offer better flexibility.

6. Choose the Right Installer

Installing large format tiles requires specific tools and experience. Make sure your installer has handled big tiles before—they’ll know how to properly cut, transport, and install these heavier, more delicate pieces.

Final Thoughts

Large format tile can add a high-end, dramatic look to any room, but it’s not a one-size-fits-all solution. With the right preparation, design planning, and installer, these oversized tiles can create a breathtaking backdrop that’s both practical and timeless.
