Structure
Structure of Black Hole Formation & Mass Classes
Stellar black holes contain a few to many tens of solar masses in ordinary examples, intermediate-mass candidates span roughly hundreds to hundreds of thousands of solar masses, and supermassive black holes contain millions to billions of solar masses. These categories describe mass scale, not fundamentally different objects.

Stellar black holes form when no stable neutron-star configuration can support a collapsing core or compact-object merger remnant.
