How can you tell the difference between when a complex is going to be either tetrahedral or square planar?

I don't believe we have to differentiate between the two, so either answer would be correct.

Tetrahedral shape is formed when there are four electron densities, which are four bonds with no lone pairs and square planar is formed when there are six electron densities, consisting of four bonds and two lone pairs.

Tetrahedral occurs when the shape is AX4E0. Square planar occurs when the shape is AX4E2. Fyi, in AXnEn, X is the number of bonds, while E is the number of lone pairs in the central atom.
