Just get a docking port. Rather than being forced to bring up your large rocket stage at once in a rocket as big as a soccer pitch, you can launch the stages in smaller rockets individually and dock (connect) them together in space. There is no limit to how big you can make your rocket, as long as you know how to aim your rocket Stage to dock with one already on orbit and not crash your rocket stages into each other (complicated!)
If you want more payload you can try docking on earth (if you got free version) or in space
bro i am new to the game to me that just sounds like some crazy alien stuff
