pcb design four layers pcb

I have some two layer boards, but I want to design more layers pcb now. Can you suggest any pitfalls to be aware of for my first attempt, the price of four layers is more expensive than 2 layers,so I'm hoping to not waste the 2 layers pcb.

For combining the 2 layer boards to 4 layer boards, you need to consider the stack-up carefully.

If the pcb you need are running very large currents, tracks on the inner layers have higher thermal resistance to the ambient air, so the pcb need to be designed wider for the same ampacity.
