For a conventional slab, 3 1/2". If you go 3 1/2" on a post tension slab (and some builders do...) the tops of the cables will be just below the top of the surface and surface cracks will form above the cables. I have even seen where the power screed will cut into the black cable cover.

What is the minimum thickness for flat slab?
The minimum thickness for a flat slab typically ranges from 4 to 6 inches (about 100 to 150 mm), depending on factors such as structural load, span length, and the type of concrete used. However, local building codes and design requirements may dictate specific minimum thicknesses. It's essential to consult structural engineering guidelines and regulations for precise specifications tailored to the project.

What is the minimum of flate slab design?
Since most flat slabs contain reinforcing steel, the minimum would be the thickness required to cover the steel, generally 2" top and bottom. But the real answer depends on what the slab is supporting and the level of safety required. For a very general situation where the slab is supported on all sides and not significantly longer in one direction, a slab can be 6" wide and support light loading if properly reinforced.
