The Chandrasekhar limit is the maximum size of a white-dwarf, not a neutron star. It's usually defined as the minimum size of a neutron star (since it has to overcome electron-degeneracy pressure). The TOV limit[0] is the maximum size of a neutron star.

How much bigger can a neutron star be given the TOV limit vs. the Schwarzschild radius winking the whole thing into a black hole?
Ah yes - you’re right.

I was thinking of neutron stars all along - which, correct me if I’m wrong, look like they have similar density to an atomic nucleus and for which the upper limit is apparently 3 Sols. [0]
