Are you interested in only high mass stars?... i.e., stars with ZAMS mass $\gtrsim 30$ M$_{\odot}$?

@DaddyKropotkin Not necessarily. Are there medium-mass stars that can get bigger than high-mass stars?

Bigger in terms of radius? Yes, since the stellar radius also depends on the metallicity and the stage of nuclear evolution that the star is on.

How big could a regular star in supergiant/hypergiant phase theoretically get, not counting quasi-stars?
