Choosing the right tile thickness is just as important as selecting the right color, finish, or pattern. Tile thickness affects durability, load-bearing capacity, installation method, and long-term performance. Whether you are planning a residential renovation or a commercial project, understanding the best tile thickness for floors and walls will help you avoid costly mistakes and achieve the best results.
This guide breaks down recommended tile thicknesses by application, explains the key factors that influence your choice, and offers practical tips for different spaces.
Tile thickness is not only about strength. It influences several critical aspects of a project:
Durability & load resistance – Thicker tiles generally handle heavier foot traffic and loads better
Installation method – Thin tiles may require more precise substrates, while thick tiles need stronger adhesives
Height alignment – Floor tile thickness affects transitions between rooms and adjacent materials
Cost & logistics – Thicker tiles often weigh more, impacting shipping and installation costs
Using the wrong thickness can lead to cracking, uneven surfaces, or premature wear.
Floors are exposed to constant foot traffic, furniture weight, and sometimes heavy equipment, so tile thickness is especially critical.
Standard residential floors: 8–10 mm
High-traffic residential & light commercial: 10–12 mm
Heavy commercial or public spaces: 12–20 mm
Outdoor floors (terraces, patios): 18–20 mm (2 cm porcelain slabs)
Better resistance to point loads (heels, furniture legs)
Reduced risk of cracking over time
Improved performance on uneven or demanding substrates
Porcelain floor tiles, due to their high density and low water absorption, can often perform well at slightly thinner profiles than ceramic tiles, while still maintaining strength.
Wall tiles do not bear weight in the same way floors do, allowing for thinner and lighter options.
Standard wall tiles: 5–8 mm
Large-format wall tiles: 6–9 mm
Decorative tiles & mosaics: 4–6 mm
Flexible or lightweight wall materials: 3–5 mm
Reduced load on wall structures
Easier handling and faster installation
Better adhesion, especially on drywall or lightweight substrates
For vertical applications, flatness and consistency are often more important than sheer thickness.
Different materials perform differently at the same thickness.
| Tile Material | Common Thickness | Typical Use |
|---|---|---|
| Ceramic tile | 6–10 mm | Walls & light-duty floors |
| Porcelain tile | 8–12 mm | Floors & walls |
| Large-format porcelain slabs | 6–12 mm | Modern walls & floors |
| 2 cm porcelain pavers | 18–20 mm | Outdoor floors |
| Mosaic tiles | 4–6 mm | Feature walls & accents |
| Flexible stone / soft ceramic | 3–5 mm | Walls & curved surfaces |
There is no single “best” tile thickness for every project. The ideal choice depends on where the tile is used, the material type, traffic level, and installation conditions. Floors typically require thicker, stronger tiles, while walls benefit from thinner, lightweight solutions that are easier to install and maintain.
