90x90 vs 120x120 tiles: key differences

Feature	90x90 tiles	120x120 tiles
Installation ease	Easy	Medium to difficult
Visual impact	Balanced modern look	High-end, dramatic
Versatility	Very high	More limited
Ideal spaces	Medium to large	Large / open spaces
Subfloor tolerance	Good	Low

When to choose 90x90 tiles

Choose 90x90 porcelain tiles if:

• you want a modern look without technical complications
• the room is not perfectly regular
• you are renovating and the subfloor is not perfect
• you need a flexible and reliable solution

👉 It’s the “safe choice” that works in most situations.

When to choose 120x120 tiles

Choose 120x120 tiles if:

• you have large, open and well-lit spaces
• you want a seamless, minimal design
• you are working on a new build or perfectly prepared subfloor
• you are aiming for a high-end architectural result

👉 It’s the “premium choice” with maximum visual impact.

The most common mistake to avoid

Choosing tile size based on looks only.

Many people go for 120x120 tiles because they look more modern, without considering:

• subfloor quality
• actual room size
• installation complexity

👉 The result can be poor installation or a disappointing final effect.

Conclusion: which tile size is better?

There is no universally better option.

• 90x90 tiles → versatile, safe and well-balanced
• 120x120 tiles → bold, premium and more demanding

The right choice depends on the balance between:
👉 design
👉 space
👉 technical conditions

If you’re planning a project, the best approach is to understand all available tile sizes first, then choose based on your specific space.
