The minimum slab thickness is controlled and reported automatically according to Codes for flat slabs.
The minimum slab thickness is controlled and reported automatically according to Codes for beam-to-slabs.

Symbols in ACI 318-19
h = overall thickness, height, or depth of member, in.
ln = length of clear span measured face-to-face of supports, in.
fy = specified yield strength for nonprestressed reinforcement, psi
αfm = average value of αf for all beams on edges of a panel
Minimum slab thickness
There are two different slab thickness limits according to flat slab and beam-to-slab.
Flat slab thickness limit
Beam-to-slab thickness limit
