FAQ: What thickness should exterior stone have?

Exterior stone thickness depends on the project structure, fixing method, and the level of mechanical stress expected on the facade. Buyers should never choose thickness only by visual preference.

For reliable facade work, the supplier and installer should agree on thickness early so the cut, fixings, and final appearance all work together. That avoids surprise adjustments on site.

The best answer is the thickness that matches both safety and visual design, not just the lowest possible cost.
