Transistor density scaling decoupled from "node size" (however you want to describe it) years (decade??) ago. Also, scaling also really depends on what you're building (logic vs cache for example). That being said, looking at like a 10-30% increase in density per node step will probably get you a rough estimate - though you'll certainly need to dig into whatever specific claims each foundry advertises for each new node.
