A space habitat one kilometre in diameter if circular, or long if it were some sort of "barbell" arrangement, would have to rotate at 1.34 RPM to generate a 1g centripetal acceleration. That's well within the estimated human comfort zone. Up to 2RPM is reckoned to be acceptable, however, and halving the diameter to 500m would give you 1g at 1.89 RPM, but with a less massive structure.

Mind you, that's still really big.
Akima:
Sitnspin is a remarkably apposite handle for this discussion. ;)

But it’s still peanuts compared to space.

If we're going with that rationale, a galactic cluster is tiny compared to the universe
