We know the matter that goes in is a certain size. Maybe we can deduce the total size it is compressed to? And the size the blackhole gains.

It’s impossible to know based on the current understanding of physics. A black hole is formed when the inward gravitational force exceeds the neutron degeneracy pressure of a sufficiently massive object, which is what keeps neutrons from occupying the same space (not really, it’s complicated). Beyond that, only conjecture exists with no evidence.
