CG is a factor with LOx the denser of the two liquids not only Saturn 5 but
the SpaceX Falcon 9 as well. Starship is a completely different beast.

Hi everyone,
Just a question that came to mind when looking at some booster designs;
what determines the positions of the fuel and oxidiser tanks? For example,
the Saturn V features its Lox tank placed above the Kerosene tank, however
on SpaceX’s starship it’s fuel tank is above the oxygen. Is this to do with
density and propellant mass? Maybe the pressure the tanks are held at? And
would this be relevant to small-scale liquid fuelled rockets?
Kind regards, Charlie.
