Hi Chris, everyone.
Yes, I read that, but as a single planet gets bigger, its gravity goes up, even if you use progressively less and less dense materials. You soon hit the point where it has to be some super science engineered device. Let us say that it is a hollow world. (Gravity on outside, free fall inside.) That could work, you could make a 'planet' arbitrarily large that way.

But then you need a super strong material, to support it. If people dig down 75 meters on Cidri, do they hit some sort of grey metal that nothing can go thru? Volcanoes are right out, right? No real geology, just stuff that mimic's geology, right? Huge world have to spin, really, really fast to make the sun go around every 24 hours right. But on a gigantic world that would reduce the force of gravity. OK, well, we can increase the mass of Cidri to make up for that, but then gravity changes as you move north and south, right? Maybe we don't have one sun, but two small ones, close in? No, that does not make sense, because you couldn't get seasons to work.

Anyway, I decided that in my campaign, Cidri was multiple worlds connected by huge gates, hundreds or thousands of km long.

It just seemed easier than working out the physics of an arbitrarily huge world.

Warm regards, Rick.
